How to Cool a Garage With No Windows: 5 Best Tips

Home With A Garage And Driveway

No one wants to work in a sweltering workshop or garage and ventilation is one of the cheapest means by which you can keep things cool in the area. Unfortunately, not every garage is conducive toward having windows to easily open up and keep the cool air of the outdoors flowing inside for free. People living within condominiums or row houses are likely to be the most aware of this situation; such places usually wedge the attached garage between buildings, offering no reason for windows.

This article has been penned in order to solve the issue of keeping a garage nice and cool when windows are not, or cannot be, an option. Hopefully, at least one of these suggestions will be just the solution to those unbearable days when the ambient temperature heats the air with nowhere for it to go. Another thing to note is that not all of these solutions are exceptionally costly, making this guide suitable for most situations and budgets.

How Much Cooling Do You Require?

Before considering cooling solutions, it is best to consider the average amount of time spent in the garage and how cold the garage needs to be. If your garage is mostly used as a storage space, you may just need a short-term of portable approach. Conversely, if you’re multi-car garage doubles as a base of operations for your hobbies, DIY tools or work bench, your attention would best be directed toward permanent means of repelling hot air. Lastly, anyone using a garage to store temperature/humidity-sensitive valuables would best be served with a comprehensive HVAC system.

Pro Tip Number 1: Simply Open the Door

Depending on the angle that sunlight is coming from and your garage’s level of insulation, opening the door of your garage may be just the cheap trick you need to keep things cool. If your garage door faces north, you will be bringing shady air into the stuffy interior of your garage, bringing the temperature down with it. When opening the door for ventilating the garage, it is important not to forget to also open the human entrance if one is present.

Pro Tip Number 2: Try Portable Fans

Improving the ventilation within your garage helps to suck in the cool air and expel the hot kind. Because a stiff breeze helps to cool the skin, an industrial floor fan can do a massive service to your cooling needs, especially if positioned near an open door and pointed near the garage. In situations where the garage has a small side door, consider pointing the fan in such a way that it blows outward, sucking the cool air through the garage door. This tip’s effectiveness may vary based on your specific floor plan-some layouts may require multiple fans.

One benefit of a portable fan over an air-conditioning unit is that fans tend to cost less money and require significantly less upkeep. You do not need to worry about chemicals like freon when it comes to a portable fan, you merely need to commit to some seasonal scrubbing around the blades to wipe away the collected dust.

Pro Tip Number 3: Install a Ceiling Fan

A high-powered, ceiling-mounted fan will ensure that you always have a cool breeze to greet you upon entering your garage. Make sure to pick up an industrial fan over a residential version-this will ensure that you will gain the most power and maintaining the fan’s blades will take a minimal amount of work.

Pro Tip Number 4: Install Attic Vents

Anyone who remembers their elementary school science lessons knows that heat rises. Installing some vents in the attic of your garage will expedite the diffusion of heat within your garage. For optimum efficiently, place the vents along the highest points of your residence.

The created flow of air will ventilate the garage and keep it cool through passive convection; cool air is kept near the low portion of the garage while the hot air leaves before it can settle along the ceiling and saturate the garage with smothering humidity.

Pro Tip Number 5: Augment the Room’s Insulation

When addressing the leading cause of excessive heat within a garage, the garage’s inferior insulation tends to be a common suspect. Insulation does more than just keep the heat locked in during cold weather temperatures common to winter, it also does a capable job of trapping heat inside of the room. If you discover that your garage is sorely lacking in insulation, see if you can refit the walls with cellulose insulation, in the case of walls with an interior finish, or batt insulation, in the event that you can see the studs on your walls.

Adding insulation to your attic and even to your garage doors can also leave a noticeable impact on the ambient temperature of your garage during the hot months. Furthermore, the presence of sufficient insulation works wonderfully with the other solutions featured in this guide, amplifying their effectiveness.

Last Words

While no one solution is ideal for every home, a keen understanding of the frequency that you use your garage and how much you are willing to spend on cooling solutions can greatly pare down your options. Regardless of how you go about keeping your garage at a comfortable temperature, reaching that state is an easily accomplished task.
