Picture this: You wake up on a lovely summer day and make your way directly to the garage to get some work done. However, when you pull open the garage door, you instantly feel a wave of humid air. This is not what you want to experience just before doing some work. Maybe you were contemplating doing some woodwork, re-potting a few of your plants, or you just want to give your car a polish. It can be difficult to focus on any type of work when there are high temperatures in an enclosed space. This is true, even if you have a running fan.

Installing a garage air conditioner is the best way to assure that your workspace is cool and provides comfort. However, there are some things to consider beforehand. In this article, we discuss why homeowners should opt for the best ductless for garage Plainville CT. We also cover why central heating and cooling systems and window AC units are not viable options.

Why Air Condition Your Garage?

People utilize their garages for a number of reasons besides just a place to store their vehicles. Garages can be used as gyms, games rooms, or even workshops. If you are going to put in the time in your garage, a space that is uncomfortably hot is the last thing you need. Moreover, cracking open the windows is not entirely a guaranteed way of cooling down your garage. If you do opt for an air conditioner, it should be noted that there are a few challenges that you will have to work through. However, there is one option that we’ll discuss below that can help you create the perfect environment in your garage.

Challenges With Air Conditioning Your Garage

If you happen to have a central HVAC system in your house, do not use it to cool your garage. The reason being is that chemical substances in your garage like pesticides, gasoline, and running engines can emit gases, or toxic fumes. These can get into the ductwork and be distributed throughout the house.

Like many, you might think that you can easily solve the heat issue in the garage by using a ductwork extension. However, this is a bad idea because you will violate the housing inspection code. Also, a ductwork extension can put tremendous strain on the central air conditioning system because you will need to cool a very large volume of air. Most air conditioners are sized to meet the cooling needs of your home, which does not include your garage.

The Problem With Volume

It is important to take into account the issue of air volume. To start, there is a good chance that your garage is the largest space in your home relative to the other rooms in the house. In addition, very few garages have ceilings that are complete. This means that the air volume is included in the space that spans the rafters up to the roof. Therefore, your garage can have nearly 50% more air volume relative to a different room that is the exact same size but has a complete ceiling.

Less Insulation

Garages are not insulated, so it is very hard to maintain a cool temperature. Even if you use a state-of-the-art air conditioner, this is the case. Before you try using your central air conditioning system in your garage, it is critical to insulate the ceiling, door, and walls. This will help lessen the volume of air that needs to be cooled. Another thing you should consider is your indoor air quality.

The Quality Of Your Indoor Air

Connecting the central HVAC system in your home to your garage may seem like a good idea. However, it could result in indoor air quality that is poor. It is crucial that the AC unit has a balanced flow of air. The typical rule for airflow is that for every cfm (cubic foot per minute) that enters, there has to be a cfm that is released. So if the AC unit draws in 1,200 cfm from your house and releases 800 cfm, the extra 400 cfm will have to come from somewhere. It might be drawn in from the gas water heater, under the walls, or the garage.

The gas water heater situation can be fatal. If the water heater is firing and the HVAC system draws air down the flue, the fumes will not rise upwards in the flue. This is called back-drafting and it can cause carbon monoxide to be released in your house. There can be lethal consequences if you breathe the gas into your lungs. Even when there is no back-drafting in the gas water heater, you can also increase the garage pressure while decreasing pressure in the rest of your home. If this happens, all of the air particles that are toxic will be distributed in your house.

The Proper Way To Air Condition Your Garage

If you often use your garage and an air conditioner is definitely required, be sure to choose a system that is not connected to a central HVAC unit. It should only be for the garage. The best decision in this situation would be a ductless air conditioning unit or a ductless heat pump. This is a great choice because it conserves energy, it is small, can be easily switched off. Furthermore, you don’t need ducts. Using window units is the other inexpensive choice. That being said, expect more noise and less effectiveness. Most people do not prefer this choice as they cost less initially but come with a slew of issues.

Different Ways To Cool Down Your Garage

Window AC Units

Despite being the least feasible way to air condition your garage, this is the least expensive. This is why many homeowners decide on a window AC unit. If your goal is to reduce the temperature in your garage by simply a few degrees, this option will do the trick. However, if you want your air conditioner to work more efficiently, then this is not the best approach to choose from.

Basically, using a window or wall unit is not the best method of cooling your garage because you will have to make a large hole in the wall of your garage. Cutting the hole will surely look unattractive, especially when you consider that most garage walls occupy the front of the home. However, your biggest concern should be the problem of security. In the case that a robber wanted to enter your home, they could just shove the AC unit out of the hole.

In addition, it is known that window units are noisy and inefficient. They cost a lot to run. Also, it is difficult to track down a technician or to fix the parts if the unit develops an issue. Basically, window units will not give you the results you are looking for.

Ductless Air Conditioning Units

If you reside in an area that gets weather conditions that are extreme, a ductless AC unit should be your top option when it comes to cooling or heating your garage.

A ductless mini-split AC system is very similar to a central HVAC unit. The smaller size is the only difference. The smaller AC unit has a heat exchanger that you can put on the exterior of your garage. Cold liquid runs along lines in the wall. The cool liquid brings down the temperature of the air found in an output unit that is very small. The lines run across a cut that measures a few inches. You can situate the output unit wherever it is will have the highest efficiency.
