Garage Ventilation in Summer

Garage Ventilation in Summer Summertime is a good season to make positive changes to garage ventilation that will improve its air quality. If it’s attached to your home, the improvements will extend into your home, since garage air often seeps indoors.

Air Quality in Garages

How you use your garage influences its air quality. If you use it to store your vehicles, hard equipment, chemicals for the yard and home, chances are its air quality is fairly low. These products emit volatile organic compounds (VOCs) that harm health in the short and long terms.

Vehicles and gas-powered yard tools emit carbon monoxide and other noxious gases from fuels. Paints, finishes, and chemicals also emit harmful gases, especially in the summer when temperature inside the garage climb.

Ventilation Techniques

Increasing fresh air in the garage is possible by using open doors and windows or installing exhaust fans that will pull the polluted air out in the summer. If you want year-round ventilation, consider kitchen or bathroom fans. They do an effective job at garage ventilation in a two-car garage. There are also larger kitchen fans that will handle larger garage spaces.

Fans that use motion sensors or timers add convenience. A motion sensor that triggers the fan whenever the garage door opens or closes will keep exhaust gases from building in the garage.

Special Considerations

Installing a garage fan isn’t necessarily a do-it-yourself project, especially if you have a:

  • Gas water heater in the garage, an exhaust fan can pull exhaust gases, including carbon monoxide, out of the vent and into the garage’s air.
  • Air handler in the garage for your HVAC system. An exhaust fan will change the air pressure in the garage that could interfere with the operation of your HVAC system.

Before proceeding with a fan, contact your HVAC professional to find alternatives for ventilating the garage.
