8 Best Ways to Cool Down A Garage

As the saying goes, ”summertime is always the best time of what might be.” But if you live in Florida or one of its south-central sister summer hotbeds, it has always been summer for you. When the average temperature hovers around 89°F, the garage is one area in the house that warms up quickly. And getting the space to cool requires a few techniques.

A garage gets warmed up by factors that may or may not depend on the temperature outside. Some factors include the garage ventilation, the color of paint used on walls, and having other warm heat-radiating objects in the area. Record-breaking heat in the United States shows temperatures can vary as much as 20 degrees across parts of a city. 

When planning to make your garage cool down, the first thing to consider is how much time you usually stay in the area. Answering this would guide your decision to provide either a temporary fix for your garage or invest in something much more costly and permanent. 

Here is a list of eight ways to cool down a garage:

Permanent Techniques to Prepare Your Garage for Summer

Suppose you are wondering 3 Steps to Your Dream of an Organized Garage. It is essential to know that long-term techniques to keep your garage cool would cost a few more bucks but are cost-effective and worth it. These techniques are suitable for people that usually spend a lot of time in the garage playing games, doing workouts, or doing other fun stuff.

Wall Insulation

Insulation is a necessity in both summer and winter temperatures. Making the adequate installation of insulation for walls, windows, and door frames lock temperature in by preventing heat transfer. It prevents cool air from the air-conditioner from escaping, and it also prevents warm air from escaping.

It is cost-effective because it is permanent, but it also saves garage owners recurring expenses on heating and cooling or at least reduces the cost drastically.

Change Garage Color

You may use bright paint colors to manage heat transfer and the overall energy consumption of your garage. You can keep the heat from the sun out with a wall colored in bright paint like cream and white, while darker colors like brown and deep blue tend to absorb heat and raise the temperature.

This technique is relatively easy to make as some people can easily find some time to do the painting themselves.

Go for Garage Ventilation

Opening your garage up for proper ventilation is a simple technique to control heat transfer in a garage. Fresh air comes in, and hot air flows out with a foul smell and built-up fumes in the area. For ventilation, it is common to open windows, doors, and even a house roof, where possible. 

You may also install a ventilation system on a wall or your roof. It is advisable to get the help of an electrician or a professional with some experience in managing electric circuit connections, preventing overload, and managing electricity costs.

Get an Air Conditioner

Getting an air conditioner is the easiest solution to cool down a warm garage if you can afford to do so. It is more costly than other techniques described, but it is cost-effective. Ensure the garage is well insulated before the installation of the air conditioner.

Air conditioners vary depending on whether your garage has a window or not. Ductless mini-splits are usually hung on the wall, while a garage without a window uses through-the-wall air conditioners installed by boring a hole through the wall.

Temporary Techniques to Prepare Your Garage for Summer

Quick fixes are ideal for garages that owners don’t stay in often, so it is okay to hold on to your funds and only invest it in temporary techniques.

Exhaust Fans

The fan circulates air in an area to reduce moisture while eliminating hot air in the process. Fans facilitate cooling by increasing the evaporation rate on the body of people present in the garage. An upgrade to the use of a fan is an air-conditioner, which is usually costlier but generally cost-effective. Other cheaper fans may be used, such as box fan, pedestal fan, powered shop fan.


A garage with high humidity increases the fungus growth rate on wood. Humidity also affects metal rust rate and the rate at which other humidity-related issues occur. A dehumidifier can help reduce moisture from the air to make the garage feel cool. A dehumidifier alone does not circulate air in the area. It only reduces the moisture content of the air. Use it in combination with a fan for the best outcome.

Avoid Parking Cars Used on a Hot Day in the Garage

Machines and objects that radiate heat and which you have used on a hot day should be kept outside the garage because parking inside a garage will further raise the temperature. You may take it into the garage after the engine cools down.

Remove Clutter

You may improve air circulation in your garage by decluttering. Consider taking out unused items and machinery that may contribute to airflow obstruction to create more space. Arrange objects that you consider helpful in the garage for better airflow with cabinet or storage racks.


Spending summer in the garage on a summer afternoon is not fun due to the scorching sun. Moreover, the two main reasons your sauna may feel like a sauna are lack of ventilation and the unavailability of proper insulation. These techniques will help you show how to effectively prepare your garage for the summer, whether you have plans for a long-term solution or just a temporary fix.
