How to Cool a Garage with No Windows: 9 Tips to Beat the Heat

If you have a garage, you know it can get super hot. But what do you do if the garage has no windows? With some smarter strategies, there are plenty of ways to keep your garage a comfortable temperature on hot days. Check out these top strategies for cooling a garage without windows.

1. Shade Trees or Awnings

One of the simplest and most effective ways to cool your garage is to use a shaded tree. This can help keeping the direct sun off your garage and reducing the heat inside. If this isn’t possible, you can add awnings to provide some shade around the garage. Even an umbrella over the door can provide welcome relief.

2. Ventilation Fan & Attic Vent

Having adequate circulation inside your garage is key. An attic vent will help keep air moving, drawing hot air out of the garage and replenishing it with cooler outside air. An electric fan is another great option – when used in combination with the attic vent, it can help draw out the hot air even faster.

3. Coolers & Air Coolers

An easy way to cool a garage without windows is to use a portable cooler or air cooler. These can both be used to help keep the air temperature down in the garage, and are relatively inexpensive. While air coolers are more effective, coolers can help with long-term cooling by freezing ice packs and placing them in the garage.

4. Window Film & Plastic Wrap

If you garage is constantly exposed to the sun, window film can help reduce the heat and UV rays it absorbs. It reflects the sun’s rays off the surfaces of the garage and can make the entire space significantly cooler. Another option is to use plastic sheeting to cover up windows. While it doesn’t keep air out, it can deflect some of the heat away from the garage.

5. Opening and Closing Doors

By opening and closing the door of your garage, you can create a vacuum effect that reduces the heat inside. Simply opening the door briefly and then closing it again will **** out some of the hot air and replace it with cooler air from outside. This isn’t the most permanent solution, but it can be handy in a pinch.

6. Cold Water Sprays

Cold water sprays can provide a unique way to cool the air inside your garage. Hang a wet towel over an open window, or use a misting fan to spray cold water into the room. The water evaporates, taking the heat with it and cooling the air naturally.

7. Paint & Insulate

Making sure your garage is insulated is key for keeping the temperature down. Light-colored paint can also help reduce heat absorption. Both can make a big difference in keeping the garage cool and comfortable.

8. Portable AC or PAC

If your garage has electricity, you could consider using a portable air conditioner or personal air conditioner (PAC). These can be used to cool down smaller spaces, like garages without windows, without taking up too much energy. They are not incredibly cheap, but they can provide a great solution to cooling your garage.

9. Refrigerator & Freezer

The last strategy for cooling a garage with no windows is to use a refrigerator or freezer. If you have the space, placing these appliances in the garage can help reduce the temperature. They should be used in moderation, however, as they can draw a lot of power and can add to your electric bill.

Personal Experience

How do you cool an open garage?

Cooling a garage with no windows can be a challenging task as the insulation from outside elements is significantly reduced. However, understanding some cool features and tricks can help to significantly lower the temperature in such a space. One of the most effective ways for temperature control is to use a reflective coating on the walls and ceiling. This sort of material reflects sunlight and absorbs less natural heat, reducing the ambient temperature. It’s also important to install transparent window films on the inside of the garage to trap some of the cooler air inside the structure. Additionally, adding insulation to the walls and ceiling can take the edge off the ambient temperature as insulation helps to trap the heat within the walls, or prevent it from entering. Installing vent fans are another effective way to cool the temperature in a garage with no windows as they can keep air circulating in the central portion of the room. Outdoor fans and exhaust systems can also help to reduce the temperature considerably depending on the type of fan and the space available for installation.
