How to Install Garage Vents
Walking into a garage in the summer is often like stepping into an oven. A garage without vents traps the heat, which is hard on cars and other machinery that may be stored. Adding a few vents to allow airflow not only lowers the garage temperature, it also keeps nasty or even deadly fumes from building up when the doors are closed. Does this Spark an idea?

Purchase plastic or metal vents at your local hardware supply store. The more vents the better, but if you choose to only put in a few make them as large as possible.
-
2
Place vents on at least two exterior walls. Higher is better for the exhaust vent but intake vents can be placed lower on a wall if necessary. In order for the heat to move out, cooler air must enter the garage. Even when the wind is not blowing a natural flow will circulate the air slowly.

Cut a hole the size of the manufacturer's recommendation. Use a circular saw or saws-all to rough out the hole and make any adjustments necessary. Insert the vent from the outside to test the fit.

4
Run a bead of caulk around the edge of the vent and mount it using the screws provided. Ensure the caulk creates a good seal to keep water out during heavy storms.

Consider a powered fan for a large garage or when it isn't possible to vent from multiple walls to release the heat. Contact an electrician to run any new power lines to ensure the project meets local codes.
