Choosing the Right Garage Air Conditioner
You have three choices when it comes to cooling your garage:
- Ductless Minisplit
Finding the right garage air conditioners 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 air conditioners inside of your garage. You will get better results from insulation alone than air conditioning without insulation.
Window Unit – $
Window air conditioners are ugly, they can be noisy, but they work well. You’re in the garage anyway, you likely won’t mind the noise!
If you are looking for a budget pick, window air conditioners are the best all-around buy considering cost-effectiveness.
While they are cheap, they still push as much air if not more than the portable air conditioing units while using less electricity to boot.
If you just want a way to cool down the garage without breaking the bank, window air conditioners are a perfect option. Window units these days can be easily installed by yourself with a little elbow grease.
Portable – $$
Portable air conditioners are the easiest option out of the three. They require little installation and no outside help. They aren’t the cheapest or the best at cooling but they are convenient.
The main benefit of a portable garage air conditioner is that you don’t have to use it just in the garage, you can use it elsewhere.
The downside though is that you do need to vent out the hot air somehow, either through a window or the garage door.
Portable AC units are the best option if you are looking for a no-hassle way to cool your garage and are willing to pay a little bit extra for the convenience factor.
Ductless Mini-split – $$$$
Ductless mini split air conditioners are the best option although it is costly.
Ductless mini split air conditioners 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 ductless mini split air conditioners 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, then ductless mini split air conditioners are the best way to cool a garage.
I didn’t include evaporative coolers in the list because not every person will be able to use an evaporative cooler. They’re only effective in hot, dry climates making them useless if you live outside of the southwest and parts of Texas/Colorado.
Best Overall Portable Garage Air Conditioner
For a 400 square foot garage, you’re going to need at least a 14000 BTU air conditioner.
This portable air conditioner is going to be perfect for a two car garage, not to mention that you can take it inside with you wherever you go in the home!
If your garage gets humid as well as hot, you can use the dehumidifier function. That’s going to be great when it’s not too hot in the garage, but the rainy season is starting to take a toll on your garage.

Enjoy from the 3 fan speeds, 24 hour timer and a remote control. You’ll be able to quickly turn off this portable air conditioner anywhere in your garage.
This unit also has thermal overload protection to protect not only the air conditioner, but you and your home.
Sadly, portable air conditioners aren’t the most efficient garage cooling options.
I would recommend a window unit over a portable air conditioner, but you may want to be able to take it inside with you to justify the purchase.

If the power cuts out, don’t worry, the automatic restart function will bring it right back to where you left off.
Enjoy the 24-hour timer, temperature control from 61 to 89F, a full functioning remote and an auto drain function. Reviewers mention that this unit was a great fit in their garage and especially enjoyed the dehumidify options.
Sadly, this unit uses dual hose exhaust which can be a bit tricky to set up as the hot air can get mixed in with the intake which will make the portable AC unit borderline useless.

You’ll be able to enjoy not only the full featured remote, but also the digital touch panel on the front for ease of access.

Humidity can destroy a garage, and with the dehumidify mode, you won’t have to purchase a separate garage dehumidifier.
It comes with a window installation kit so you’ll be able to enjoy from cool air in a matter of minutes.
While it isn’t as efficient as a window air conditioner, you’ll still be able to enjoy from its low power consumption.
I like that the front has an automatic swing mode for the vents so you can get that cool air moving all across your garage. The low noise level motor is a nice touch as well if you want to enjoy some peace and quiet every now and then.
Compared to the other garage air conditioners on this list, it is not the most aesthetic. Still packed with features though!

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?
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 than portable units.
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 better performance-wise.
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?
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.
If you’re after one of the best garage air conditioners while still being portable, then the Honeywell 14000 BTU Air Conditioner is a great option. If you aren’t on a budget and don’t mind an expensive installation, you may want to go with the mini-split PIONEER WYS012GMFI22RL.
Consider insulating your garage before installing air conditioning. You may find that the insulation does enough and you don’t need to spend any more money on your garage.
