Choosing the Right Garage Air Conditioner

You have three choices when it comes to cooling your garage:

  • Portable
  • Ductless Minisplit
  • Window

Finding the right garage air conditioner depends on your needs and your budget. My personal recommendation would be to go with a window unit.

Regardless of which unit you decide to buy, a dehumidifier is suggested to keep energy costs at a minimum. You should also insulate your garage before you even think about putting an air conditioner inside of your garage. You will get better results from insulation alone than air conditioning without insulation.

Window Unit – $

They’re ugly, they can be noisy, but they work. You’re in the garage anyway, you likely won’t mind the noise!

If you are looking for a budget pick, the window unit is the best all-around buy considering cost-effectiveness. While they are cheap, they still push as much air if not more than the portable units while using less electricity to boot.

If you just want a way to cool down the garage without breaking the bank, a window unit is a perfect option. Window units these days can be easily installed by yourself with a little elbow grease.


Portable ACs are the easiest option out of the three. They require little installation and no outside help. They aren’t the cheapest or the best at cooling but they are convenient.

The main benefit of a portable garage air conditioner is that you don’t have to use it just in the garage, you can use it elsewhere.

Portable AC units are the best option if you are looking for a no-hassle way to cool your garage and are willing to pay a little bit extra for the convenience factor.

Ductless Mini-split $$$$

The Ductless Mini-split is the best option although it is costly.

A Ductless Mini-split works like a normal AC unit with an attachment that goes outside. Wall-mounted AC units are incredibly great at keeping rooms cool but do cost a pretty penny when it comes to installation.

Having used a Ductless Mini-split in the past, I can vouch for them keeping the air incredibly cold. Most units can also do heat as well so that is a bonus.

The cost+installation averages to around $4000-5000. If you have no budget. Ductless Mini-split is the best way to cool a garage.

Only one hose is required to set up. This means that there is a drain on the bottom of the air conditioning unit which requires to be emptied after a fair amount of use. Be wary of this before purchasing.

It is on the heavier side at 78 pounds. If weight is an issue for you, look into purchasing another unit that is on the lighter side.

While it is a bit pricy, the overall consensus is that this is the best portable AC unit out there.

Garage Air-Conditioner FAQ

1) How to cool a garage with no windows?

Your only options are using a fan or a Ductless-Minisplit air conditioner.

The Ductless-Minisplit does require professional installation and is pricy. If you are looking to save money, another option would be to get a window installed and purchase a window unit. Altogether it would still be cheaper than a Ductless-Minisplit (around $4000-5000).

You should also think about ventilating your garage with an exhaust fan if you have no other options.

2) What is the best garage air conditioner for me?

Everyone has their own preferences and budget. Personally, I would only buy a window unit. The portable AC units are known to be less energy efficient and cost much more than a standard window unit.

You can spend around 300 dollars with a much better result.

Wanting to up the value of your house is always a good idea. That’s where Ductless Mini-splits fits in. You can eventually turn your garage into a separate bedroom with an AC installed increasing the value of your home when you look to sell in the future.

3) Will a portable AC cool a garage?

Yes, it can. Will it be the most efficient or the best use of your time? Likely not. You will have better results with a window unit or a Ductless Mini-split, both require a bit more know-how but are beneficial in the long run.

4) How big of an air conditioner do I need for my garage?

A two-car garage would require around a 9,000 to 10,000 BTU air conditioner according to Energy Star. I would advise going bigger than you think as the garage is more prone to air leaking due to the nature of the garage door.

5) Should I air condition my garage?

How much time do you spend in the garage?

You can buy a garage fan or garage ceiling instead of an entire unit to save on costs if you don’t spend much time in the garage. Dehumidifying your garage is also another option.

Being hot all the time is bothersome, and spending a lot of time in the garage working on your projects can turn into a nightmare. It’s worth it for me to spend a few more bucks to be more comfortable at the end of the day.

It can also increase the cost of your home, so look at it like an investment rather than sunk money.
