How to Improve Airflow in Garages

Shelley Frost

Garages serve as a workshop for many homeowners. Whether you repair furniture, cars or use the garage as a hub for home-improvement projects, the air flow in the space is an important consideration. Good air flow in a garage helps keep the space cool during the warm summer months.

It also helps disperse fumes from projects you complete in the space, while keeping condensation at a minimum. There are several ways to improve garage ventilation depending on the size and layout of your garage.

  1. Assess the current ventilation options in the garage that create air flow. Look for windows, vents and other opportunities to get the air flowing. Determine if these options are in working order or need repairs to be effective.

  2. Take advantage of windows in the garage. Open windows on different sides of the garage to create a flow of air. Even an opening of an inch or two will help get the air moving. If the garage doesn't have any windows, consider having some installed.

  3. Place a fan in front of an open window to help draw in fresh air. If a fan blowing into the garage disrupts items on your work bench, turn the fan around so it draws air from the garage out of the window.

  4. Open up the garage door at least partially to help create air flow in the garage. This works well in combination with an open window either with or without a fan near it.

  5. Install a gable vent if your garage has gables. These vents help improve air flow through the garage space.

  6. Install a sidewall ventilation fan if a simple vent isn't enough for the garage space. Place it opposite the garage door, leaving the door open slightly when running the fan. This creates an air stream in the garage.
