Beat the Heat: How to Keep Your Garage Cool During the Summer


A garage is where we store our vehicles, tools, mechanical appliances, and even just extra items and clutter. It’s also where some people have their laundry machines, and work on their cars. It’s a multi-purpose room that’s often used and visited.

Despite this, garages aren’t always properly ventilated or cooled, resulting in a suffocating, humid, and warm room that’s difficult to stay in. This worsens during the summer and can even damage the garage doors and everything within it.

Extreme heat, such as that during summers in Provo, can affect and damage the sensors and wirings of your garage. If left unchecked, you would end up needing garage door repair services just to have a functional garage door, and the heat could also mess up with any other electrical appliance or item stored within.

Here are some ways to avoid turning your garage into an oven in the middle of the summer heat:

Leave it Open

Opening the garage door in the morning until the afternoon would greatly help with the ventilation and prevent hot air from being trapped within the garage. Just make sure your vehicle and all items inside the garage are safe even if you leave it open.

Park Your Vehicle Outside Temporarily

Instead of parking your recently-used vehicle (which would still be radiating heat) inside the garage right away, you can consider parking it just outside first and let it rest. This would help avoid the heat from your car dissipating into the garage after parking inside and closing the garage door. Once it cools down, turn it on and then park it inside.

Fans and Ventilation

You can use portable fans or even permanent ones installed to help with the air flow in the garage. This works best if the garage has an exhaust vent or is fully or slightly open. Installing a garage ventilation system can also assist with cooling the garage. You can choose between passive ventilation that uses no energy and a spinning turbine on the roof or active ventilation that uses fans to facilitate airflow and remove hot air from the garage.

Adding or Connecting Air Conditioning

If you’re not comfortable with having an open garage door while you work inside the garage, you can use a portable AC unit, a window AC unit, or have a vent connect from your home to your garage to allow air conditioning in your garage as well.


Lack of insulation is one of the most likely causes of overheating garages. Adding insulation to your walls and the garage door could be a costly but worthwhile investment to have a cozy and cool garage throughout the year.

Less Clutter

A garage with a lot of storage boxes and other items can obstruct air flow, as well as retain heat (especially with metallic items and boxes).

Whenever summer comes or if you live somewhere with constant high temperatures, it’s best to keep these garage cooling tips in mind. Not only would you have a garage with an optimal temperature that you can work in, but also avoid damage to your car and anything else stored inside.
