Air Conditioning the Garage

You read that headline right.

garage air conditionersIt might seem like a great idea to air condition the garage but there are a lot of questions you have to ask before you jump on this project.


Most importantly, what are you using your garage for? Is it mainly to store stuff and park your cars? If that’s the case then throwing in an AC unit doesn’t really benefit you. Cars don’t need to be kept cool, and all the stuff you’re storing can most likely take a little heat and humidity anyway.

If you plan on using your garage as a wood working shop, a man cave or a hangout/ recreation room then keeping it cool comes into play. That being said, you don’t want to route your existing air conditioner to your garage. There is too much potential for dirty and dangerous air to be pulled into your home. A separate unit is the only way to go.

There are a few options when it comes to separate AC units!

  • Portable Unit – A portable is a freestanding unit that uses a tube to take in fresh air and expel heat.
  • Window Unit – Can be put in a double hung window or a hole can be made if no window exists.
  • Ductless Mini Split Unit – Works like a heat pump, uses an outdoor compressor/ condenser and indoor evaporator/ air handler. This option requires training so you’d have to consult a professional.

Don’t forget to consider how what type of insulation your garage has/ needs. Installing an air conditioner without proper insulation will certainly make it less efficient. Take a look at your garage doors as well. A high R value door will further energy savings. Here are some helpful tips Selecting the right garage door. Put your time in on research for this project so you don’t end with an inefficient set up.
