Car Air Conditioning Tips for Summer Commuting

It’s summer, so naturally we’re going to cover an A/C related topic. The car interior can become a sweat lodge if the A/C isn’t functioning optimally. Here’s a few car air conditioning tips to ensure you and your passengers don’t feel like they’re sitting in a sauna while driving down the road.

Roll the Windows Down

Keep the windows open an inch or two while parked. When you start the engine, roll every window down all the way for about a minute. This quickly shuttles the warm air out of the cabin. This also means the interior can be cooled more quickly once the air conditioning is turned on.

Raise the A/C to Its Max Setting

Turn the A/C to its highest setting. This moves a greater volume of air into the cabin, thus helping to cycle hot air out of the car and replacing it with cold air. Adjust the volume to the desired setting after about a minute. If you happen to drive a newer car model with automated temperature control, do the opposite. Set it to the lowest setting before raising it to a comfortable setting.

Run the A/C Every Week

Make it a habit to run the AC at least once a week even in the colder seasons. This circulates the refrigerant, which lubricates the A/C by keeping the seals, lines, and valves conditioned.

Use the Defrost Setting

If you notice the smell of dirty socks coming out of the A/C vents, then you likely have a dirty cabin air filter. Run the A/C on the defrost setting for a few minutes, while toggling back and forth between the A/C’s max and normal setting. If that doesn’t work, then it’s time for a tune-up from a professional.
