How to Ventilate a Garage With No Windows | 8 Tips to Cool Your Garage

A garage isn’t only used for placing your car but it’s also an area of your house to hang out and store some of your belongings. The problem with this part of your home is that it can get pretty heated up at times when there’s no windows and ventilation to let the hot air out.

Rather than avoiding this area during the summer heat, it’s a good idea to make it a place for you and your family to relax. 

In order to do this, you need to increase the ventilation of the place to let the hot air out so it can cool down.

Here, we’re going to show you a few tips on cooling down your garage.

Opening the Door

Opening your garage door is the easiest and cheapest method to cool down your garage. It’s able to let the hot air leave from the room and it with the cool air coming from outside.

This won’t cost you anything and all you have to do is open up your garage which stops the place from being insulated. If your garage also has another door installed on it, it’s a good idea to open it up to allow airflow in your garage and speed up the cooling process.

Although there are limitations to this method as when the temperature is too hot outside that there’s no way to find cool air for you to let in.

Let the Car Cool Outside

Letting your car sit outside the garage after using it is a good way to prevent more heat from entering the room. It’s able to cool down from all the heat it’s managed to gather up and slowly go back to a normal temperature.

Driving around the place while your car is being hit by the sun can cause the top part of it to get really hot.

Whenever you’re placing it back to your garage, the heat that it’s managed to collect will start to spread around the room and increase the overall temperature of the place.

Add Insulation to your Garage

It’s a common misconception for people to think that insulation can actually cause your garage to heat up more. In truth, insulating your garage can prevent the place from gathering too much heat inside. It can also help you have a warmer interior during the winter season.

Insulators act as a barrier to prevent most of the heat outside to get inside an area. This, in turn, lets your garage be in a cooler temperature compared to the heat from outside.

Investing on an Air Conditioner

Although this tip can cost you a bit, getting an air-conditioner is one of the best options to let your garage cool down. Even with just this alone, you can put your garage at an optimum temperature that’s able to let you hang around the place any time of the year.

You can get a wall air conditioner where you can set it up by just making a hole in your garage to mount it on. Another good option is to use a mini-split air conditioner which can work exceptionally well and can easily cool down your garage in a matter of minutes.

Add Ventilators

Adding a ventilator to your garage is a good alternative if there isn’t any room to place an air conditioner.

Placing vents at the roof of your garage is able to let most of the hot air out of the area. This allows more of the cooler air to enter and lower the temperature of the garage to make the place comfortable to hang around.

You can also install attic ventilators that can be mounted on the wall of your garage. They do the same work as roof ventilators but cost less and are easier to install. It also ensures that there’s always a continued airflow which is necessary to keep the warm air out.

Add Airflow with a Fan

Using a ceiling fan is an effective and energy-saving method to keep your garage cooled down.

Cold air usually stays at the top while hot air is heavier and stays at the bottom. By using a ceiling fan, it’s able to push down the cold air and circulate it around the room which lowers the temperature of the place.

A good option is to get an industrial-grade ceiling fan that works better and stronger. It’s also a good option if you’re planning to make your garage into a workplace as it can withstand dust and debris.

Use a Dehumidifier

A humidifier is able to lower the humidity of the area which is important to make your garage feel comfortable when you’re doing work. High humidity can make an area feel sweaty and uncomfortable to be in. 

It’s necessary to reduce the humidity as much as possible in order to have a cooler and better environment to stay in. 

Make sure that you’ve closed your garage to make the place more insulated so the humidifier can actually do its work.

Use Lighter Colors on the Exterior

If the exterior of your garage is currently painted in a darker shade then it’s a good idea to change it to something lighter. The color of your garage will make a huge difference when it comes to the amount of heat that it’s able to absorb.

If the roof and walls are currently painted in dark colors or even black, then it means it’s absorbing a lot of heat which can go inside your garage. 

Painting your garage with lighter colors will reflect the heat from the sun and prevent your garage from becoming a giant oven.


Cooling your garage to a more comfortable temperature is really easy as long as you can decide which would be the best solution. Though it’s always important to find one that is able to stick to your budget and what your future plans are for your garage.
