How Can I Cool My Garage Without AC?


Before you go out to find a solution on how to cool a garage, you’ll need to determine the usage scenarios of your garage. Are you going to use it for a few hours every day? Or will you be using it for prolonged periods  throughout the week? Will you be getting in the garage on the weekends or mornings?

Furthermore, where is your garage situated? Is it located in a shady location? Or does it face the sun the entire day? How many devices or tools do you have in your garage?

These questions are especially crucial as large electrical devices give off heat. If your garage doesn’t have ventilation or windows, this heat can make the interior space hotter and stuffy. Write down all these questions, and then determine the cooling mechanism you want.

If you mostly store goods in your garage and seldom ever have a prolonged sitting, it’s not worth investing in something more costly and permanent because the benefits won’t be as great as the cost.

However, if you frequently use your garage as an avocation station or workplace, and relish having prolonged sessions in this area, and possibly even have a gaming station, searching for a long-lasting solution that has a much higher cooling output makes sense.

The other crucial point is that it’s important to maintain ideal temperatures and dampness levels when storing worthy goods in your garage. Sensitive items such as wooden furniture, paintings, electrical appliances, and many more can be damaged in extreme dampness and heat.

With your needs now written down, we’ll discuss the options for cooling your garage without AC.

Insulate the Wall of the Garage

Within the house, garages are among the most poorly insulated spaces. This room may become unbearably sultry during summer. If you have a garage that isn’t insulated and would like to spend significant time there, then wall insulation is among the best methods of cooling a garage and should be a priority on your to-do list.

Besides insulating walls, garage door insulation also does a great job in keeping your inner space chilly and cozy.

Furthermore, there are no recurrent costs of energy associated with this type of work. Just set up the insulation, and then you can unwind for many years without spending a dime on utility bills per month.
