Why You Should Choose A Garage Air Conditioner

People use their garages for a number of purposes besides simply storing their vehicles. A garage can be used as a gym, games room, or a workshop. If you plan on being in your garage for some time, the last thing you need is for the space to be uncomfortably hot. Even opening the windows is not a guarantee that you will be able to cool down your garage. If you decide on installing a garage air conditioner, it should be noted that there are a few drawbacks.


paint and chemicals in garage

If you already have a central air conditioning unit in your home, you should not utilize it to cool your garage. The reason being is that some of the chemical agents that you keep in the garage like pesticides and gasoline, as well as an engine that is running, can emit toxic fumes that will get into the ductwork. Consequently, these fumes can be spread through the rest of your home.

You may believe that adding a ductwork extension to the garage will solve the problem of excess heat easily. Yet, this is a bad idea and will cause you to violate the housing inspection code. Furthermore, when the extension is in use, it will put a great deal of pressure on the central air conditioning system because it will need to cool a huge amount of air.


Another issue that needs to be considered is volume. Firstly, your garage is probably the biggest space in your house relative to the other rooms in the house. In addition, few garages have ceilings that are complete. This means that the space from the rafters up to the roof is included in the air volume. Therefore, the air volume in the garage could be up to fifty percent higher than other rooms that are the exact same size and have complete ceilings.

Lower Insulation

Typically, garages are not insulated. So, it is very hard to keep them cool. This happens even if you are using a state-of-the-art air conditioning system. Before you try using your central AC system in the garage, it is crucial to insulate the walls, ceiling, and door. This helps by decreasing the volume of air that needs to be cooled. Indoor air quality is another thing you should consider.

Indoor Air Quality

If you connect your central HVAC system from your house to the garage, it could result in bad indoor air quality. It is essential for your AC unit to have airflow that is balanced. The fundamental rule for airflow is that for every cubic foot per minute (cfm) that enters, there must be a cfm that exits. Thus, if an AC unit draws in 1200 cfm from your house and returns 800, the remaining 400 cfm has to come from somewhere else. That 400 cfm could be taken from under the walls, the gas water heater flue, or from the garage.

The gas water heater flue could be fatal. If the air conditioner draws air down the flue when the water heater is firing, the fumes will not be able to move up the flue. This situation is called back-drafting. It can result in carbon monoxide being released in your home, and that can be lethal if you breathe it into your lungs. Even when the gas water heater is not back-drafted, you can increase the pressure on your garage and decrease pressure in the other parts of the house. This could cause those toxic air particles to make their way to your home from the garage.

The Proper Way To Air Condition Your Garage

If you use your garage often and an AC unit is absolutely essential, be sure to choose a system that is not connected to the central AC unit. It should be just for the garage. In this case, your best option would be a ductless heat pump or a ductless air conditioning unit. This is the ideal choice because it is small, conserves energy, can be turned off with ease. Also, it does not require ducts. Another cheap option is to use a window unit. However, be aware that window ACs are less effective and noisier. This is why many people do not prefer this option.


Options For Cooling Your Garage

Window Air Conditioning Unit

Even though this is the least workable method of air conditioning, it is the most economical initially. This is why many homeowners opt for it. If your goal is to cool your garage down by just a few degrees, then this option will do the trick. However, although they come with a low initial price tag, they have high operating costs. Therefore,  if you want your air conditioner to be more efficient, this is not the best choice.

For all intents and purposes, using a window or wall unit is not the best way to make your garage cooler because you will need to cut a large hole in the wall of your garage. It will definitely look unappealing to cut the hole, especially when you consider that most garage walls are situated in the front of the home. However, your most important concern should be security. If a thief wanted to enter your home, they could just push the air conditioner through the hole.

Window AC units are also known to be noisy and very inefficient. If they develop a problem, it is not easy to find repair parts or a technician. Basically, you will not get the results you desire.

The Advantages Of A Window Air Conditioner

  • They are very inexpensive compared to state-of-the-art units and portable systems.
  • It is easy to install the unit on your own.
  • You can plug it into a regular outlet in the wall. However, if you use more than one unit, the circuits might overload.

The Disadvantages Of A Window Air Conditioner

  • You have to create a large hole in the wall.
  • The hole size might be a problem if you want to replace the unit with another one. The hole might be too small or too big for the next unit.
  • You will experience security issues.
  • In honesty, they are unappealing to look at and noisy.
  • You might not get the results you are expecting.
  • They have high operating costs.
  • These types of units can encourage the growth of mold, so you will have poor indoor air quality.

The Advantages Of A Ductless Unit

When it comes to heating or cooling your garage, a ductless air conditioning unit should be your first choice if you live in a region that has extreme weather conditions.

A ductless mini-split AC system is much like a central AC unit except that the size is smaller. The smaller AC system has a heat exchanger that you put on the outside of the garage. Cold liquid is transported via lines in the wall. This cold liquid cools the air in a very small output unit. The lines run across a cut that is just a few inches. You can place the output unit in a place where it is the most effective.

The Benefits Of A Ductless Air Conditioner

  • They are more durable than many central AC systems.
  • They are rated as being one of the most effective ways of air conditioning.
  • They are extremely energy efficient.
  • Ductless systems are whisper quiet.
  • They are small, so they do not take up a great deal of your wall space.
  • You will not need to cut a large hole in your wall, so you will not have security problems.
  • In addition to a cooling system, it can also be a heating system.
  • Optimally designed to provide you with the ideal temperature.

Disadvantages To A Ductless Air Conditioner

  • This is the most costly option compared to various other types of units.
  • Only a professional can manage the installation. Be sure not to buy these devices online thinking that you might save money because you might have regrets.
  • Even though you may have a reason for wanting to remove it, the unit often becomes a permanent fixture.

Common Ductless FAQ’s

How Does A Ductless Air Conditioning Unit Work?

A ductless AC unit has an indoor air handler and an outdoor heat pump. The air handler’s function is to distribute air that has been conditioned directly into your garage or home.

How Easy Is It To Install A Ductless HVAC System?

It is relatively simple to install a mini-split unit. An HVAC contractor will drill a small 3-inch hole in the wall of your garage and connect the cables between the air handler and the outdoor unit. It is a fast and simple process. If the installer is skilled, the process can be done in just one day.

Where Else Can I Use A Ductless Mini-Split System?

Besides the garage, a ductless unit can be used in room additions, sunrooms, rooms with temperature issues, and as an energy-efficient supplement to your central HVAC system.

How Costly Is A Ductless Heating And Cooling System?

The price that you pay for buying and installing a ductless HVAC system varies depending on various factors. These include the price of the indoor and outdoor unit, the unit’s capacity, and the installation. One essential thing to note is that the installation will be more expensive for multi-zone ductless set-ups.

Why Are Ductless Systems So Energy-Efficient?

One of the major benefits of installing these AC systems is that the temperature can be customized. You can turn them on when you are physically in the garage so you don’t have to heat/cool unoccupied space, unlike central HVAC systems. They are also more efficient because there is no ductwork. Experts say that when there are leaks in the ductwork, about 30 percent of energy on average is lost. With a mini-split version, you will not have these types of problems. Also, they come with high SEER and HSPF ratings.

Ductless units are designed to help maintain a constant temperature in the home. This happens whether they are running on low or high speeds.This helps to reduce the issue of energy that is connected to regular cycling.

Can A Ductless Heat Pump Be Efficient Even If I Live In An Area With Extremely Cold Temperatures?

You will discover that every ductless HVAC unit manufacturer creates heat pumps that work in cold climates. These types of pumps are called extended capacity units. There are versions that can provide high-quality performance in the coldest of temperatures.

What Is The Durability Of A Ductless System?

In general, a ductless unit runs for up to 20 years or more, provided it is regularly maintained. You can identify and fix potential problems with the help of a professional.
