Published on: August 30, 2013

You may be one of the many people in the Southeast U.S. who uses their garage as a workshop as much as a place to park your car. Typically, garages are not insulated and can become stifling hot and uncomfortable. Adding an air conditioner may be the perfect solution.

How to Air Condition a Garage:

  • Window units:
    • Very economical choice
    • Great for occasional cooling or smaller spaces
  • Portable air conditioners:
    • Versatile and relatively inexpensive
    • On wheels to enable placement where needed
    • Often very noisy

How to Air Condition a Garage Using a Window Unit:

  • The size of the needed unit is determined by the square footage of the garage. Start with the premise that a 500-square foot garage will require a 12,000 BTU air conditioner.
  • Know the required BTUs and the measurements of the window before purchasing any unit, and be sure electricity is available.
  • Use strips of insulation, wood and/or caulk to seal around the unit.

How to Air Condition a Garage Using a Portable Unit:

  • Portable air conditioners are not typically the best option for cooling a garage.
  • Depending on the garage size and the heat load, portable units may constantly cycle on and off in an attempt to lower the garage temperature. This on/off action may greatly reduce the life of the unit’s compressor.
  • Portable air conditioners should be vented outside to disperse the heated air. This can be accomplished through a window or a hole cut into the side of the garage for the exhaust hose.

How to Air Condition a Garage Using Other Options:

  • Wall mount air conditioners:
    • Good choice for garages without windows
    • Necessary to cut opening through exterior wall
    • Appropriate for larger garages
  • Evaporative “Swamp” coolers:
    • Require a water source
    • Warm air is pulled through damp pads which cool the air
    • Cooled, moist air is blown into the garage
    • Advantage of operating on standard 120-volt electricity
