What Is A Ductless Heat Pump Controller?

A controller is a ductless accessory meant for communicating with your cooling and heating system. Most controllers are a simple, handheld remote control. But, there are also newer, sophisticated ones that allow you to control your system from your smartphone.

Your indoor air handler has sensors on it that control the dehumidification, heating, and cooling of your system. You use your controller to signal these sensors to reach your desired settings. Consequently, ductless technology will work to maintain that comfort level.

Mini-splits are an energy-efficient way to solve your heating and cooling issues. Furthermore, with the right controller, you’ll reach your mini-splits full potential and easily be able to fully customize your comfort.

This article discusses the different types of ductless heat pump controls and their capabilities. It’s important to learn about each one before you decide which to purchase.

Ductless Remote Control Functions

Each controller has different features depending on the brand, make, and model. But, there are a few standard features that are on all controllers. They are listed below:

On/Off Display

This feature indicated if the unit is currently operating.

Mode Setting

The mode setting lets you choose between four modes. They are typically AUTO, DRY, COOL, and HEAT. AUTO mode allows the system to automatically change between COOL and HEAT modes. Your system will switch to HEAT when the temperature is low and COOL when the temperature is high.

DRY mode cycles the compressor on and off for a couple of minutes, depending on the temperature of the room. COOL mode is used to cool the room, usually in the hot season. Lastly, HEAT mode is used to warm up the room, typically in the cold season.

Economical Mode

This mode activates the sleep or economy function. When in use, your mini-split raises the set temperature in increments. For example, the temperature increases by one degree after an hour, two degrees after two hours, and so on. This mode is usually used when at night when the occupants of the room are sleeping. The economy mode also helps save energy.

Fan Speed

The fan speed can be changed to Low, Medium, High, or Auto. The Auto speed automatically changes based on the temperature of the room.

Timer

The timer allows you to set a specific number of hours until your system turns on or off.

Air Louver

The air louver allows you to direct the airflow where you want it. Some units have a left and right control, others have an up or down control.

 

Basic Controls

Indoor units come with a handheld controller. However, many homeowners are surprised when their indoor units do not come with a smart thermostat.

Similar to a TV remote, the handheld controller lets you communicate with the indoor unit. It allows you to turn the indoor unit on or off. You can set a specific temperature, and change whether your system is in heating mode or cooling mode. Lastly, it allows you to change the airspeed and the vane direction. Some controllers also have sensors and timers that make for convenience and comfort.

This type of basic controller may work for you if you just have a single-zone unit for an infrequently used room. On the other hand, if you have a multi-zone ductless setup, you will likely want a controller that will allow you to easily manage them from a single source.

Programmable Controls

If you are considering a multi-zone mini-split system, then you will want a device to control all the indoor units with one controller. You’ll soon realize that it’s quite a hassle to go to each zone and control each individual unit.

Programmable thermostats have the standard functionality of a controller. But, they also have an added feature called automated daily settings. This feature lets you pre-program your choice in temperature ranges for any day. Its technology allows it to work through walls. This lets all your connected units receive the settings and work based on what you set, like the fan speed, temperature, airflow direction, and operation mode. You can also decide when the units will turn on or off and how long they will operate.

The programmable controller should be the same brand as your mini-split system. Otherwise, you’ll have an incompatible controller that won’t be able to communicate with your indoor units properly.

Smart Controls

Smart thermostats have lots of capabilities including scheduling set parameters. They also have features that show current weather notifications and predict how to adjust the settings. The smart controls remember your comfort preferences and learn what settings you like based on the time of the day.

Some smart thermostats come with multi-zone sensors. These sensors help with home security and safety. They can detect the humidity and occupancy of the home. It’s able to ensure that each occupied room receives air at the preferred temperature. It can also control your humidifier, dehumidifier, and ventilator.

Smart thermostats are able to connect with security devices like carbon monoxide detectors, smoke detectors, and cameras. You can receive notifications to your phone that alert you if your home’s temperature is at a dangerous level. This is very helpful in situations where a pipe might burst due to the cold or your pet might get sick due to the heat.

One downside to smart controllers is that they can be quite expensive and more complicated to install. Each indoor air handler requires a smart thermostat and a thermostat adapter to be installed by a professional. This is called dry contact and allows the systems to communicate with each other. Some smart thermostats might not even work with certain mini-split heat pumps.  However, if it does, you might experience problems with functionality like controlling humidity or adjusting the fan speed.

 

Wi-fi Adapters

A smart thermostat is a great option. But, if you want home comfort without the extra cost and confusion, a wi-fi adapter might be a better choice. A wi-fi adapter has the same settings as a programmable controller with the convenience of a smart thermostat. It is easy to use and the price won’t go over your budget.

Before purchasing a wi-fi adapter, make sure it is compatible with your specific mini-split. The device has to be installed in each indoor unit. It is controlled with an app that can be downloaded on your smartphone, tablet, or computer. After it’s set up, you’ll have complete control of your unit at your fingertips. With this, you’ll be able to control the temperature settings, airflow, dehumidification, fan speed, and more.

Integrated Controls

If you already have a heating and cooling system but are thinking about supplementing it with a mini-split, consider purchasing a RedLink controller. It allows you to control all your mini-split units with integrated control.

With RedLink Technology, you can connect up to 16 devices with your heating and cooling system. Also, you can manually operate devices from your smart device or a central controller. It won’t interfere with any other wireless devices in your home. This is a great way to supplement your current HVAC system and save on energy costs.

 

Conclusion

Knowing the differences between each type of controller is important so you can create the best home comfort strategy to suit your home’s needs. If you want more information on how controllers allow you to personalize your heating and cooling system, contact a qualified HVAC technician. An HVAC expert has lots of knowledge and experience to help you choose and install the best controller for your heating and cooling needs.

Ductless Mini-Split Wiring

 

Mini-splits are a popular and energy-efficient choice when it comes to cooling and heating your home or business. The indoor unit and the outdoor unit make up the mini-split. The outdoor unit includes the condenser and the compressor. The indoor unit provides warm or cold air in different zones of the house. However, there are also cables that connect the units which are vital for the system’s performance.

A mini-split is typically easier and quicker to install than central heating and cooling systems. But, they are a bit more complicated than window AC units, which you just need to plugin. Mini-splits require their own electrical line that is connected to the electrical panel in the house.

Contact a ductless HVAC expert if you are considering a mini-split system for your home. A skilled and experienced professional will be able to help you find a system that works well with your heating and cooling requirements. Likewise, they can install it, using the wiring needed, and guarantee that your mini-split will work correctly.

Ductless Heat Pump Wiring: Things You Should Know

In this article, you’ll learn everything you need to know regarding ductless mini-split wiring to ensure your system works as expected.

Electrical Service

The outdoor unit uses power from the electrical service panel with a disconnect box and a surge protector. These are connected with electrical wires that are protected by a weather-proof wire called a whip.

Depending on the size and model, mini-splits have different power needs. Most of the systems require 220 volts or higher, although some of the 9k to 12k systems may only need a 110-volt service. It’s essential that the breaker panel is sized correctly and can handle extra voltage because these systems are permanently connected in the electrical service panel.

To be sure the system is wired correctly, contact a professional HVAC technician to help you. This is the only way you can make sure your system is up to code and that the warranty remains intact.

Call Today: (908) 707-1776

Wire Gauges

Mini-split systems require a specific wire gauge. The connecting wire needs to be quality and the right size. If not, it can be hazardous. They should also be UL-listed for sun exposure. UL-listed wires have passed the safety tests of the Underwriters Laboratories. An expert technician can make sure your electrical wiring meets these requirements.

The standard sizes are 2, 6, 8, 10, 14, and 16-gauge wire. The thickness of the wire determines how much current can pass safely through it. Lower wire gauges are thicker and can handle more current. A higher wire gauge is thinner and can handle less current. For example, a #14 wire can handle 15 amps and a #6 cable can run 60 amps.

Connecting Cable

A connecting cable, also known as a four-conductor cable, is a wire that goes between the outdoor and indoor units. It carries information and supplies power between these two parts of the mini-split. Typically, systems use a 14 AWG 4-conductor stranded cable. It is also commonly run through a conduit to abide by local codes.

Disconnect Box: Non-Fused Versus Fused

A disconnect box, also known as a fuse or switch box, has the controls to supply the energy to your mini-split. An HVAC professional can turn off the power to your mini-split system when they are repairing or performing maintenance on it. It is mandated to install one near the condenser.

Most homeowners commonly prefer a non-fused disconnect box rather than a fused box. The breaker in the service panel has the protection a fuse would provide. Homeowners can reset circuit breakers themselves, but a fuse has to be replaced. Fuses can be hard to find and replace by yourself. Fuses can also be damaged by the elements and make the system unsafe.

Electrical Whip

The electrical whip can be found outdoors. It is made up of high-voltage wires that are hidden in a case to protect it from the rain, sun, and other elements. They are primarily used to connect the 120v/220v power from the disconnect box to the condenser.

 

How An HVAC Contractor Wires A Ductless Mini-Split

Next, we need to find out how mini-split systems are wired. Installing a mini-split can be quite challenging. It is recommended that you hire a licensed HVAC contractor to install the system. If you attempt it yourself, you might harm the unit or even yourself.

The steps below are how a professional will go about installing a mini-split.

Step 1: Install A Disconnect Box

To comply with the code, it is required to install a disconnect box. A professional will run a 230/208-volt or 155-volt line from the house’s primary break box to where the disconnect box will be installed typically next to your unit. An expert technician will be able to make sure the required voltage is met.

The two hot leads are wired together to the fused connections in the box. Then, the faceplate and on/off switch will be attached.

Step 2: Attach The Electrical Wire Whip

A technician can run an electrical whip from the disconnect box to the unit. An electrical whip is an outdoor grade wire that meets the code while keeping the process easy.

Step 3: Connect The Ductless Wires

Next, the electrical wires will be connected to your mini-split according to your unit’s specifications. The exact specifications of the connection will depend on the model of the mini-split. A professional technician has the knowledge and experience to connect the electrical wires properly.

Step 4: Connect The Wires From The Indoor Unit To The Outdoor Unit

The number of connections you have determines if you have a single-zone or a multi-zone unit. A multi-zone unit is numbered by a professional for cross-referencing to make it easier to connect the wire colors with their number. They will also ensure each indoor unit in a multi-zone system is connected to the correct input of the required line set. This is important because your mini-split will not function correctly if this is not properly executed.

Step 5: Connect The Wires In The Indoor Air Handling Unit

Similar to the outdoor unit, the indoor unit’s connections need to be made in the right order. The ground wire and the three main wires need to be connected to the proper terminals. Some units require round crimp-style terminals to make the connection more secure. A professional will know if this is necessary for your installation.

The electrical part of the installation is completed once all the above steps are finished. Contact a trusted HVAC professional if you have any questions or concerns about the electrical wiring of your mini-split system.

Protecting Your Ductless HVAC System Investment

All HVAC systems are considerably expensive. Although manufacturers offer warranties to cover any unfortunate circumstances, they may not protect damages done by electrical surges.

Surges can occur from a lightning strike or a power surge. A surge or an irregularity in the power supply damage the electrical components of your mini-split system or possibly a complete system failure. This could happen even if your mini-split system is just a couple of years old.

Install a surge protector to avoid these damages. They are easy and quick to install, and a licensed HVAC technician one in just over 10 minutes. Installing a surge protector is simple and it will protect your system.

 

Conclusion

Contact a licensed and knowledgeable professional for an easy mini-split installation. They have the experience and training to make sure it is wired properly. Rest easy knowing your mini-split will work effectively and at its optimal efficiency.

Ductless Condensate Pumps: What You Need To Know

To put it in simple terms, condensation is when vapor is converted to liquid. The air condenses into water droplets on a cold surface when hot air comes in contact with it. An example of this is when you go out with a cold can of soda on a hot day. The droplets you see on the can are formed as the humid air is cooled beyond its dew point.

A mini-split system is one of the top cooling solutions on the market. It can capture humidity from inside your home and properly let it go outside. As a result, you have drier indoor air for an extra cooling effect. Your skin’s moisture also evaporates, which, in turn, cools your body down, and the cooling sensation is felt. In this article, we discuss what you need to know about the ductless condensate pump.

Learn More About Mitsubishi Ductless Systems Call To Schedule A Free, In-Home Estimate

Is Condensate Harmful?

If condensation is not correctly eliminated from the air inside your home, it can create multiple problems. These water droplets will pool as time passes, causing damage to your ceiling, floors, walls, and other possessions. It can also cause mold to grow around your home. This will affect not only your home and your health as well. Molds can trigger skin allergies or respiratory illnesses like asthma.

Without proper drainage, condensate will not only cause damage to your property but also affect your family’s overall health. It greatly impacts your indoor air quality. Repairing these damages can cost you a few thousand dollars. Therefore, the condensation must properly drain away from your home.

Call Today: (908) 707-1776

How Do Mini-Splits Remove Condensate?

A mini-split system has different ways to get rid of condensate. Depending on the make and model, some units employ a gravity-drain tube while some need pumps. Here are a few of the common ways mini-splits remove condensate:

Pipe Runs

Floor and wall-mounted units usually do not feature condensate pumps. Instead, they depend on gravity-draining to eliminate the water. The drain line must, therefore, be sloped downward.

You should ensure that the drain line runs through a hole and that it is at least one-fourth to one-half inches higher inside than it is outside. This way, the line is angled down so that it can remove the accumulated moisture correctly.

Drain Tubes

Almost all types of floor-mounted and wall-mounted units use drain tubes to get rid of condensation. It is the most common way and it makes use of a 5/8″ inner diameter vinyl tubing.

One of the things to ensure when you are using this flexible vinyl drain tube is that it does not get kinked. Otherwise, water will not be properly drained. The condensate might even overflow and damage the indoor air handler. Use a braided tubing instead of the basic clear tube as it has lesser chances of becoming kinked.

Pumps

There are some cases where gravity-reliant drainage is not feasible. This is when a condensate pump comes in. It is made up of a 1” or 1 to 1/4″ PVC instead of the usual tubing. This allows the pump to maintain enough slope over a long horizontal run.

It is possible to connect several indoor air handlers to a single drain line. Ensure that you check the manufacturer’s guidelines during such applications. Moreover, refer to a professional technician’s recommendations to make sure that the line can manage the amount of water that all connected indoor units will create.

Concealed ducted, ceiling suspended, and ceiling cassette units usually feature built-in lift pumps. Whereas, floor and wall-mounted models are meant to be mounted high up a wall that they can drain the condensate without the help of a pump. However, if the unit is installed on the ground level, then you need a condensate pump to remove the water to a more suitable location.

 

What Are The Basic Components Of A Pump?

Condensate pumps are generally comprised of two essential parts, namely, the reservoir and the float switch. The reservoir is linked to the indoor unit’s drain pan. It is where the collected water goes during your mini-split unit’s cooling operation.

It is only when the condensate reaches a specific level that the built-in float switch turns on the condensate pump. The float switch functions as a warning bell as well. When the condensate pump does not operate properly, the float switch turns off the indoor air handler to keep the condensate from overflowing.

 

Types Of Condensate Pumps

All condensate pumps are made for the same function, which is to eliminate condensate. However, there are several types you can choose from. It is recommended to know the options you have and the benefits each has. This information, along with your preferences, will help you determine the type of condensate pump that will best serve your needs.

The various types of condensate pumps include the following:

Standard

This style of condensate pump is discreet and compact. The reservoir is installed inside the indoor air handler. This way, you are sure that it is hidden out of sight behind a wall or a ceiling. It also operates quietly. It works well with most applications as standard condensate pumps are typically the plug and play type.

Call To Learn More About Ductless Heat Pumps

Low Profile

If you are searching for a condensate pump that is less intrusive, then go for a low profile one. It is meant to be fitted inside the condensate pump so that it is entirely away from view. This type of unit is also one of the slimmest of its kind, as it is designed to be the most inconspicuous pump in the market.

High Suction

A high suction condensate pump is installed much like a standard one. The difference is that a high suction pump comes with extra suction power. Therefore, it can lift condensate higher and further. It is ideal for when the indoor unit is installed below ground level. When this is the case, the water needs to be pumped to a higher level before draining it outside. It is also perfect for when you are looking to minimize noise as a high suction condensate pump can be installed further away from your living space.

Surface Mounted

A surface mounted condensate pump is installed directly below your mini-split system. The reservoir and pump are placed in a compact box outside of the unit. Due to its location, a surface mounted pump is easy to access when you need to clean or repair any part of it. A surface mounted condensate pump is, therefore, an excellent choice for applications where easy access to the reservoir is crucial.

Four Common Ductless Condensate Pump Installation Mistakes

Installing mini-split condensate pumps without the proper knowledge, tools, and experience can result in errors that can be detrimental to the equipment’s functionality. Common condensate pump installation mistakes include the following:

Pump Omission

Many mini-split systems are not equipped with a condensate pan because the water is drained with the help of gravity. However, there are situations where gravity draining is not an option. When this is the case, a condensate pump is needed. Failure to determine when a situation calls for a condensate pump can lead to issues as drain pan overflow.

Explore How Ductless Systems Work

Pump Selection

The most common installation mistake is choosing the wrong pump. Installing an incompatible pump to your mini-split system can lead to issues such as poor performance and a high level of noise. It can also affect the ease of installation or maintenance and the aesthetic you are going for.

An example of poor pump selection is choosing a sizeable wall-mounted pump. A large wall-mounted pump is not necessarily designed for mini-split units. Therefore, they are not aesthetically pleasing and have higher sound levels.

Wiring

Condensate pumps need a line-voltage power that is wired to the mini-split unit’s electrical terminal. Different mini-split units have different pump wiring requirements for powering their systems. Therefore, no one diagram can accommodate all mini-split make and models. This is one of the reasons why incorrectly wiring a condensate pump is a typical installation error.

Siphoning

Another common installation error is the incorrect routing of the discharge line that creates a siphon. A siphon can cause an airlock, which can either cause an overflow or damage the pump. It can also restrict correct draining, and the condensate will eventually overflow.

A few condensate pump manufacturers offer anti-siphoning devices at no added cost. An anti-siphoning device is a two-inches long molded plastic fitting that prevents the pump from auto-siphoning. It has an omnidirectional design, which means it can be installed either horizontally or vertically. This design ensures that incorrect installation does not occur.

 

Do I Need Professional Installation?

If you are unsure which condensate pump is the best one for you, or if you have any concerns regarding compatibility, then contact a professional mini-split installer. Conducting a DIY ductless installation when you do not have the proper tools, knowledge, or experience may save you a few dollars. However, you are putting your system at risk of damage from incorrect installation. The same goes for hiring an unlicensed technician.

Professional installation ensures that you get the best out of your mini-split system. This means that all the components of your mini-split, including the condensate pump, will work at optimum capacity for a long time. Not only that, but you also make sure that the unit’s factory warranty remains intact.

Ductless Line Sets

Ductless line sets connect the indoor air handler with the outdoor condenser unit. These line sets are essential components when it comes to the ability of your mini-split system to provide heat and cool air. They help move refrigerant throughout the system. Therefore, it is essential that your HVAC company selects and installs the line sets correctly. Otherwise, the mini-split system will not be able to function as it should.

This article will offer the information you need to learn about the importance of a mini-split system’s line set.

Learn More About Mitsubishi Ductless Systems Call To Schedule A Free, In-Home Estimate

Ductless Line Set: What Is It?

A ductless line set uses two copper tubes in order to connect the indoor air handler to the condenser outside. The copper tubes are different sizes. One tube is larger than the other. The smaller tube is the discharge or liquid line. Its purpose is to transport the liquid refrigerant that the mini-split system uses to the indoor air handler to absorb heat. The larger of the tubes is the suction line. This suction line carries the heated gaseous refrigerant out to the condenser so that the heat can be released.

The refrigerant, liquid and gaseous, will circulate continuously through the two copper lines to provide the conditioned air you desire. The direction the refrigerant travels will depend on whether you want cooling or heating. In other words, when you want heat, the unit will reverse the flow of the refrigerant.

 

Multi-Zone and Single-Zone Ductless HVAC Setups

If you are using a single-zone mini-split system, then you’ll only need to purchase one single line set for your unit. However, if you are using multi-zone systems in your home, you’ll need to buy a line set for each indoor unit. Other things you’ll need to consider are the total length of the line, diameter, and distance. Otherwise, it’s possible your mini-split system won’t function the way it should. An experienced HVAC contractor will be able to determine what you need prior to the installation of your ductless system.

Branch Box

Additionally, there are some multi-zone units that require a branch box to move refrigerant from the outdoor condenser unit to the unit indoors. This branch-box will also require a line set of its own to connect it to the unit outdoors. Branch boxes are manufacturer-specific, meaning that not all combinations of branch boxes are supported. Therefore, careful consideration of the right HVAC company for your mini-split installation is important. An experienced ductless installation company will know which branch box is right for your specific ductless system.

Call Today: (908) 707-1776

Port Adapter

Your HVAC contractor might also recommend the use of a port adapter. When the line has a fitting that doesn’t match the standard fitting on your ductless system, this port adapter will help make the connection possible. Some homeowners think that a port adapter will instead restrict the flow of refrigerant. You can rest assured that these port adapters’ design ensures that it does not impede the flow of refrigerant. When an HVAC contractor uses a port adapter, they won’t need to make modifications to your current line to complete the installation of your ductless system. This type of adapter allows HVAC contractors to use the correct line size without worrying about the size of the fitting.

Of course, the company that you choose for the installation of your ductless system should always adhere to the recommendations put forth by the manufacturer when determining the sizing for a refrigerant piping connection. This is a big reason why you should not consider the installation of a ductless mini-split as a DIY project. It is something that requires the experience and knowledge of a trained and licensed HVAC contractor for the best results.

Accessories For Line Sets

The following three accessories are designed to ensure your experience with a mini-split system is as easy as possible.

Rectorseal NoKink

This is an accessory that is simply a flexible connection that is used between the mini-split system’s evaporator and the refrigerant line. The 3-inch copper stub and NoKink technology make installation easier. This accessory prevents kinking in the refrigerant line and, in turn, helps save labor costs and time during installation. It also helps to ensure that your mini-split system is functioning at its peak of efficiency.

Ball Valve

The ball valve has been designed to allow easy suspension of the flow of refrigerant without the need for removal of the seal cap. This item makes the servicing of refrigerant lines fast and easy. Additionally, it allows for fast charging with a Schrader valve. This accessory is a necessity for servicing multi-zone ductless systems because it allows a technician to work on the system without having to make sure lines have had the refrigerant removed.

Line Set Covers

This is an accessory that helps protect and hide the copper lines used by your mini-split system. Without the line set cover, the line set used in your system would be exposed to rain, direct sunlight, and other outdoor elements. It’s important to keep in mind that exposure to UV rays can cause your line sets to deteriorate faster than they should. The line set cover provides a barrier against weather conditions, protecting the line set needed for your system.

Additionally, the line set cover can easily be painted. This allows you to paint the cover to match your wall so that it can blend into your design seamlessly. When you value the aesthetic appeal of your home, this is a great perk.

Sizing Of The Line Set For Your Ductless Mini-Split

There are various sizes of line sets. The size your system needs will depend on things like the make and model of the mini-split system, number of evaporators used, size of the condenser, and distance between units. Each manufacturer has predetermined the line set size needed. Therefore, it is always recommended that the installation company you choose for your ductless system has the experience to know exactly which size your mini-split system will need.

Diameter

Typically, the line set size will correspond with the size of the mini-split system. This means that the higher tonnage or BTU (British Thermal Unit), the larger the line set diameter will need to be. Mini-split line set sizes will be indicated by numbers. The diameter of a system’s liquid line is the first number, and the suction line diameter is the second number. For example, a large line might have a ¾” diameter for the liquid line and a suction line diameter of ¾”. The smaller line set has a liquid line set diameter of ¼” and a suction line diameter of ½”.

Distance

This is simply the maximum length line set that your mini-split system will need. This length is an important factor for your HVAC contractor to calculate as it will impact the location for both the indoor unit as well as the outdoor unit. Furthermore, when the distance is measured, make sure that any bends or corners in your home are also taken into consideration. In order to ensure an accurate measurement, vertical rise and wall thickness must also be considered.

If you hire a ductless installer who is inexperienced, you might find that you have issues with the installation of your mini-split system. You might discover that the indoor unit is placed too far away from the system’s outdoor unit. In a case like this, your ductless system will not be able to operate properly because the distance exceeds the maximum length that is needed.

Refrigerant

The distance between your ductless system’s indoor and outdoor units impacts the refrigerant in a line set. When you buy a ductless system, it will have already been charged with the necessary amount of refrigerant. For most installations, this factory charge will be sufficient. However, if the installation of your mini-split system requires a longer line set, your HVAC contractor will often need to add additional refrigerant in order to ensure your ductless system is able to function at its maximum capacity. Your contractor should have the knowledge and experience to be able to know how much additional refrigerant will be needed for your home installation.

 

Quality

Just like other purchases you make, it’s important to ensure that the line sets your contractor uses are of high quality. This way, they can provide years of service. You can check if annealing was done on the line set. This is a heat-treating process and will ensure the copper tubing is able to flex without kinking or breaking. The product should also include a minimum manufacturer’s warranty of five years.

Line sets that are high quality will have flared ends. This makes installation easier because there is no need for the HVAC contractor to braze it. Additionally, the line set should have a minimum insulation thickness of ½ inch. The insulation should also have a UL listing for water-resistance as well as a rating for smoke and fire. This will all help to ensure that the use of the line set will be safe.

Incorrectly-Sized Line Sets

Problems are common with improperly-sized line sets. Here are some issues that you might encounter if the line sets are too big or too small:

Undersized

A suction-line that is too small can result in too little operating pressure for your system. This can reduce the efficiency and capacity of your ductless system. It can also lead to a reduction in the lifespan of the system.

Similarly, an undersized liquid line can result in both the outdoor unit and indoor unit not receiving an adequate amount of refrigerant to operate properly. This can also reduce the operating pressure of the unit. If this happens, your ductless system will not function properly and won’t be able to operate at its maximum capacity.

 

Oversized

When a suction line is too big, the refrigerant pressure can be to low for the required needs of the system. This can result in inefficient transport of liquid to the compressor. This can mean the compressor will not be able to operate properly because there isn’t enough refrigerant for the compressor to be able to release a build-up of heat.

If the liquid line is too big, it will hold too much refrigerant. However, this should not happen. The liquid will easily become diluted. In turn, this can damage the compressor because there isn’t enough refrigerant for proper functioning.

Conclusion

In order for your ductless system to function at maximum efficiency and provide optimal performance, the right supporting components are necessary.

Should My Furnace Smell Like Heating Oil?

Heating oil is one of the primary fuels that help keep homeowners warm during the winter season. It is low in cost but high in efficiency, making it the perfect furnace fuel for many American homes. However, there are some cases wherein the heating oil smell seeps throughout your house. Naturally, homeowners worry when they smell something unusual, especially if it’s the distinct oil smell. If you have an excellent containment system in place, then this shouldn’t be an issue. The odor will most likely disappear quickly. Ask for professional assistance from Skylands Energy Service on the rare occasion that the smell persists. An HVAC expert can help you find the root cause of the problem and achieve high indoor air quality.

Is A Heating Oil Smell In My Home Normal?

It is not normal for the smell of heating oil to permeate throughout your home. However, there can instances where it can happen. Some situations may be minor, while others are severe. Below are some of the most common reasons for the lingering heating oil smell.

A Recent Oil Tank Refill

It is not unusual for you to smell heating oil after a recent tank refill. There will be a faint lingering smell that should go away after a few days. If the scent doesn’t dissipate after a couple of days have passed, then oil might have been spilled by the delivery crew. When this happens, try to use an absorbent cloth to stop any further spread. Remove damaged materials if there are any, then clean the surface with water and soap.

Rest assured that Skylands Energy Service offers safe and reliable heating oil deliveries in Central New Jersey. We make sure that all our fuel delivery services are completed without any problems, including spills. Contact us today to know more about our hassle-free heating oil delivery services.

The Initial Furnace Use

Heating systems are idle during the summer months. Homeowners only turn them back on when the need arises. Therefore, when the temperature drops and you switch your system on again after it has not been in use after a long period, expect to smell oil. This is perfectly normal, and the smell will fade away soon.

A Clogged Furnace Filter

A blocked furnace filter can result in your unit releasing an oil smell throughout your home. Look at your HVAC air filter to determine if this is the problem. Keep in mind that the furnace air filters should be changed regularly. If replacing the air filter doesn’t solve the problem, then there might be another reason for the heating oil smell. Call Skylands Energy Service immediately.

 

An Underlying Furnace Problem

The odor could be a sign that your furnace is experiencing a more pressing problem. The oil might not be able to combust completely. Therefore, the dregs can be what is causing the smell to linger. Another cause is a cracked oil burner. The fumes will escape through these cracks and be circulated throughout your home. It could also be due to a faulty heat exchanger. An experienced HVAC contractor from Skylands Energy Service should be able to pinpoint the issue and help you resolve it quickly.

Is An Oil Smell Dangerous?

How the oil smell can affect our health is the usual concern of many homeowners. This is especially true when the oil tank is located in an enclosed area like their basement. Heating oil is not as dangerous as natural gas. This means that getting exposed to low concentrations of oil fumes is not as toxic. Heating oil will also not explode in case a leak happens. Even if this is the case, it is always better for your health and well-being that fumes are avoided at all costs.
Any repercussions from short-term exposure should be gone as soon as the smell disappears. Make sure that you are not exposed for long as this can result in serious health issues. Seek help from an expert HVAC technician as soon as you notice the lingering oil smell in your home.

What To Do If You Smell Heating Oil?

Perform the recommended actions as mentioned above. Replace the furnace air filter, inspect your furnace’s burner to see if there are any cracks, and check if there are any oil spills on the ground. Make sure that your heating unit is turned off until the issue is resolved. You should also ensure that the area receives proper ventilation. Open the windows so that the fumes are let out. Children and pets shouldn’t be allowed to stay in the contaminated area as well.
All of these are just a few simple steps you can do for minor problems. If the smell of heating oil still lingers after doing these, contact your local trusted technician to provide you with expert assistance. There might be something more going on than what you can smell or see. It is best to leave it in the hands of a professional in this case.

 

Conclusion

A smell can be a good indicator of the dangers that we cannot immediately see or hear. It allows you to know that there is a problem that needs to be solved right away. When you smell heating oil lingering around your home, then you should not dilly-dally. Instead, find what is causing it as soon as you can. This is not a normal occurrence as your oil system should be able to contain the fumes completely. Consider calling an HVAC professional for help as they have the skills, experience, and knowledge to get to the root of the problem and resolve it quickly.

Line Sets Covers For Ductless Mini-Split Systems

Installing a line set cover gives your mini-split system a professional and clean finish. It also provides you with additional performance benefits, making it a must-have accessory for all your new and current mini-split systems.

In this article, we will discuss what a ductless line set cover is and how it helps your system.

What Is A Ductless Line Set Cover?

The line set is the copper tubing that carries the refrigerant from the outdoor compressor to the evaporator in the indoor air handler and vise versa. It has two lines: one smaller liquid line and a larger suction line. Unfortunately, line sets can be exposed to the elements and can cause them to corrode quicker and easier than they usually would.

A line set cover protects the line sets, the drain tubing, and the cable from exposure of the elements. These include UV rays that can break down the insulation of your line sets as time passes. They are designed to be weather-resistant so that your system can continue operating in tiptop shape even through the harshest of weather.

Parts Of A Line Set Cover For A Ductless Mini-Split

A line set cover is comprised of different parts that work together to ensure the correct installation. These are:

• Split line tube – this hides and protects the line set, drain piping, and connecting wire from the elements.
• End socket – this is used to seal the line set cover to the condenser.
• Vertical elbow – it is used when there is a need to make turns such as go around corners or go through soffits during the ductless installation.
• Horizontal elbow – this is used to make turns on the walls. It is put to use when there are obstacles, such as windows that need to be avoided.
• Coupling/socket – this is for when you need to connect two split line tubes in a straight run.
• Wall cover – it seals any gaps and holes around the wall penetration of the line set.

Features Of A Ductless Line Set Cover

Line set covers offer standard features to help you manage your mini-split system better. These are listed below:

Versatility

A line set is not very stylish and can ruin the aesthetics of a room. A line set cover helps because it conceals the line set from view. Not only that, but you can blend the cover with the wall as these covers are entirely paintable. Some manufacturers even have custom wraps available so you can be sure that they are in line with the aesthetic qualities that you want. Rest assured that line set covers are for residential and commercial use. Therefore, you don’t have to worry as your home or office will look professional and clean at all times.

 

Convenient

Line set covers are built to ensure that they follow the energy code requirements. They are equipped with a protective peel-off film so that it stays clean and is easy to clean as well.

Adjustable

There are also line set covers that can accommodate multiple line sets, which is essential when you have a multi-zone configuration in your home. Some even have quick snap covers to make sure that it won’t pop off.

Durable

Most importantly, line set covers are built to be durable with thick-walled construction. They undergo a process to ensure that they can stand against ultraviolet rays and protect the line set like they are supposed to. They also come with no-rust screws and a glossy finish, ensuring it can last under the elements for a long time.

 

Mitsubishi Line-Hide

Mitsubishi has created the Line-Hide system that is designed to conceal and protect the copper line set and control the wiring needed for the mini-split to operate correctly. UV rays and other elements hasten the breakdown of the insulation used for line sets. The line-hide acts as a barrier around the line set, making sure that it is not exposed to these harmful elements.

Line-Hide is made using superior quality PVC with UV inhibitors, making it perfect for outdoor use in all weather conditions. Line-Hide can also be painted on with most kinds of house paints so you can match it with your exterior décor. They can also be used indoors as it meets the UL94v-0 for interior applications.

Line-Hide comes in several sizes so that you have one that will fit into each cover diameter. Line-Hide is also easy to install as it comes with a modular design and snap-on parts. Screws are also included when they are needed in the installation. Use them anywhere you need to hide any cables, pipes, or wires.

Conclusion

After your mini-split system is installed, covering the line set with a cover will help protect it from the weather or any other damaging elements. It also makes the line set look nice and clean as there won’t be a bunch of wires hanging down your walls.

Have a professional install line set covers for you to ensure that you have the right one that fits not only your line set but also meets the aesthetics you are going for. This also assures you that everything in your mini-split is in perfect working order. Likewise, it ensures that your mini-split system is ready to provide you with comfort and energy-savings all year round.
