A cool and comfortable garage is a desirable benefit to any home, especially in a hot and humid climate like here in Florida. Whether you need to do some maintenance on your car, store items, or just relax in a cool space, air conditioning for a garage can definitely make sense. That’s the short answer. Now, let’s look into it in a bit more detail!

Benefits of air conditioning for a garage

For many people, their garage is more than just a place to park their vehicle. It might actually be considered an extension of their homes; for example, in the context of using it as a:

  • Workshop
  • Storage room
  • Workout area
  • Laundry room
  • Recreational area

In the subtropical climate of Florida, however, the use of the garage for an extended period of time can get problematic. That’s where the option of air conditioning comes in!

Air conditioning for a garage can help you stay cool and comfortable in the warmer months. It can reduce humidity, which can create a better environment for working in the garage, storing items, etc.

Different types of air conditioning systems for garages

Split system: 

A split system is a ducted system with two components: an outdoor unit and an indoor unit. Hot air is drawn into the indoor unit and as it passes the coils it cools the air down. Split systems are generally more efficient than other systems and are a common option for cooling garages. 

Ductless system: 

A ductless system is a non-ducted system where warm air is pulled from the room, and cool air is pushed into the room without ductwork. Ductless systems can be installed in smaller spaces and areas that ducted systems can’t reach. With an outdoor unit connected to the indoor unit with a cable, ductless systems are a good option for smaller garages. 

Window AC: 

A window AC unit is another popular AC option. The unit is installed in a window, the cool air is blown out, and hot air is pulled in through the back of the unit. Window units are generally small and compact, allowing you to install them almost anywhere in the garage. They’re also relatively inexpensive, making them a good option for smaller garages.

What to consider when choosing air conditioning for a garage

  • Cooling capacity: The cooling capacity of a system is the number of BTUs it can produce.
  • EER: EER stands for Energy Efficiency Ratio, and it’s a measure of how energy efficient the system is. The higher the rating, the more efficient the system will be. 
  • SEER: SEER stands for Seasonal Energy Efficiency Ratio, and it’s a measure of how energy efficient the system is over a season. The higher the rating, the more efficient the system will be over a longer period of time. 
  • Installation type: Depending on the type of system you choose, you may need a dedicated circuit, or you can plug into an existing outlet.

Maintenance tips for air conditioning systems

  • Regular inspection: A regular inspection of the system will allow you to identify any potential issues or wear and tear before they become a serious problem.
  • Clean filters: Clean filters will help your system run more efficiently and quietly.
  • Clean coils: Dirt and grime on the coils can cause your system to work harder and run louder.
  • Change the refrigerant: Check the refrigerant levels periodically and replace the refrigerant as needed.

Tips for optimizing the air conditioning performance in your garage

  • Keep the indoor temperature between 75 and 80 degrees. This will help you reduce energy costs and maintain a comfortable temperature in the garage
  • Close the garage door while the AC is running. This will help reduce the amount of air coming into the garage and maintain the temperature inside. However, never let the car motor run while the garage door is closed!


So, as an answer to our initial question: YES, an AC unit for your garage can make a lot of sense, depending on the garage’s intended use. Interested in taking the next step? Contact the Air Conditioning experts at Action Air Conditioning for more information about which system is the best for you!
