If you use your garage only as a place to store your car and lawn mower, you may be perfectly satisfied leaving that area without air conditioning. However, if you spend more than a little time in the garage or use it as a workshop, play area or place to store items that could potentially be damaged by heat, it’s a good idea to add an air conditioner to keep things cool. As you consider the question, “How do I air condition a garage?,” keep the following points in mind.


The air conditioner you choose needs to be correctly sized—that is, it must be able to produce enough cooling to keep your garage at the temperature level you prefer. In general, your A/C should have a capacity of 25 BTU per square foot of garage floor space. If your garage is 400 square feet, for example, an air conditioner with a capacity of 10,000 BTU should be sufficient.

Air Conditioner Options

  • Window units: Standard window-sized air conditioners may be the best option for your garage. They fit inside an existing window or can be mounted in an opening made in the garage wall. They require little preparation besides being placed in the window, plugged in and turned on.
  • Ductless mini-splits: Your garage is unlikely to need ductwork for air distribution, so a ductless mini-split may be a good choice. Ductless systems are heat pumps consisting of a large outdoor unit containing the main system components and several smaller indoor units that control temperatures and distribute cooled. air. The indoor units operate under independent thermostats and can be placed anywhere you want them, limited only by the length of the connections between indoor and outdoor units. One or more indoor units placed in your garage will provide plenty of even, consistent cooling for that space.
