How Do I Keep My Garage Cool?

If you have found this page, chances are you are struggling with a garage that is simply too hot. Whether you live in the South where it is hot all year, or if you live in the North where you have to deal with unbearably hot summers and strikingly cold winters, you still need to have a cool and comfortable garage.

I highly doubt you have air conditioning in your garage, as this is just not generally a thing that happens. Regardless, your garage still needs to be cool. If you use your garage as a workout area, to work on your vehicles, to do any kind of craft or hobby, or if it is a personal workshop, I guarantee you will have much more fun if your garage is completely cool.

Air Conditioners Reviews

Before we get into how to keep your garage cool, it is important to understand why your garage gets so hot. First, if your garage is facing West, meaning if it is directly in the sun’s most intense heat during the afternoon, it is going to get hot.

Garage doors also play a big part. If you have a dark garage door, or a dark color of paint on the exterior, it is going to maintain more heat. Then you have to consider the ventilation system in your garage. If there is absolutely no ventilation, the air is going to get hot and stuffy very quickly.

Also, if you have your vehicle parked inside the garage after driving it, all the heat from your motor is going to make your garage even more unbearably hot. And finally, how much insulation your garage has will play a big part in how hot it gets.

To improve the coolness of your garage, allowing you to work comfortably all through the hottest afternoons, there are many ways to go about it. Some of the best ways are by using air conditioning units, special fans, air dehumidifiers, and unique insulation.

Here we have a top 10 list of the best garage cooling solutions, and at the end of the page you will find a detailed explanation of the best ways to keep your garage cool all through the year.

How to Keep Your Garage Cool: A Definitive Guide

Now that you know all the best tools for keeping your garage cool, we can look at some more in-depth solutions to cooling your garage. These tips range from incredibly easy to extremely difficult. Depending on how committed you are to having a comfortable garage, you can spend either no money or a lot of money.

But no matter which solution you use to keep your garage cool, everything makes a different. Even if it is just a fan perched on your worktable, it is still worth a small effort to improve your comfort while working on hot days.

Park Outside

Parking outside is one of the easiest solutions I can recommend to you. You probably have not even considered it since your garage is the perfect place to park your car. And while obviously it is fine to park your car inside during the winter or overnight, if you have driven your car on a hot day, then parked it in your garage before getting to work on something, you can expect terrible heat.

Mend the situation by simply parking your used vehicle outside. That way the heat from the motor won’t stifle your garage.

Choose Your Time Wisely

This one may not be completely in your control. However, a completely free way to make sure your garage is not too hot when you are using it is to only work in the garage in the cooler hours of the day. For example, wake up early in the morning and work until midday. This will ensure no matter how hot it is, it never gets too hot in your garage.

You might also try opening the garage door to let in air, then slowly closing the garage door as the air gets hotter. The hottest time to be in your garage is definitely between 3:00 and 6:00 in the afternoon, as by then the heat has basically saturated the small enclosed space.

Fans Are Cheap

The cheapest way to effectively cool your garage even in the hottest hours of the day is to use fans. You don’t even need to use an expensive fan. Pick up a few inexpensive plastic fans and position them smartly around your garage, then set them to oscillate. This will effectively blow about a cooling wind that emulates a nice summer breeze.

I would recommend keeping your door cracked slightly to provide better airflow. While this won’t make your garage actually cooler than the air outside, it is refreshing to have the air blowing across your face. You could try a large box fan, but those can be pretty expensive.

Paint Job

One of the main reasons your garage will retain heat is because either the door or the exterior is too dark. An excellent way to make your garage naturally cooler is by choosing lighter colors for your garage door, the exterior walls, and even the roof. You may even consider buying a garage door that offers better ventilation.

Obviously, this can be a little expensive. But it can also serve as an excuse to revamp your garage in more interesting colors. If you do choose to buy a new garage door, I highly suggest picking one without windows. That way the sun cannot beam directly into the room.

Upgrade the Ventilation

Upgrading your garage’s ventilation is a surefire way to make it cooler. But it also takes a fair bit of work. You need to cut open the roof and install a vent if you don’t already have one. You can easily install a passive ventilation system that consumes zero energy. You have probably seen these before in the form of spinning turbine roof vents.

If you want to get a little more technical, you can get a mechanically powered active ventilation system. This system will require a bit more technical prowess and you may need to hire someone to do it for you. In fact, I recommend hiring a professional, as an active ventilation system requires electricity and you don’t want to mess around with that stuff yourself. This method will definitely make things cooler in your garage.

Air Conditioning

Air conditioning is expensive. You need a professional to install a new air conditioner and that costs money. It also cost money to run the air conditioner. But if budget is no issue, air conditioning is 100% the best way to keep your garage cool.

With air conditioning, you can easily set the temperature and never worry about it getting too hot in your garage. It could be 300 degrees outside and only 80 degrees in your garage. This is definitely the most expensive and most effective method for cooling.

If possible, you can always go with a window-mounted air conditioner (assuming you have a window). This method is more affordable but does require some venting. Similarly, a portable air conditioner will work well but also requires ample venting.

Insulation

Not too many garages have enough insulation, and this causes problems in the summer with heat. Additionally, not having enough insulation for your garage will render your air conditioning less effective.

By installing the proper insulation, you will drastically reduce the heat that is transferred from outside into your garage. Insulation will keep your garage much cooler in the summer and it will help your air conditioner keep the air cool without all that cold air escaping outside.

You can easily add insulation to the walls of your garage, the ceiling of your garage, and even your garage doors. Then there is weather stripping. Be sure to always seal your garage’s windows and door frames to keep the cool air in and the hot air out.
