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.

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.

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.

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.

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.

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.
