Sure, it was just a few weeks ago that we were worried about driving in the rain and how the wet weather was affecting our vehicles. Check out this customer’s leak dilemma to see what the rain can do to a car’s interior. But now we’re heading fast into the weather that makes California so great: warm and sunny! So it’s time to shift your focus from your wiper blades to your air conditioning. So, the master SLO mechanics at Certified Auto Repair in downtown San Luis Obispo have put together a list of tips to keep your AC running cold all summer long.
1. Run your AC on defrost
You should run your air conditioning weekly for 10 minutes on defrost mode on the coolest setting and at the maximum fan speed. This helps maintain gas pressure, keeps your compressor running well, cleans out moisture and prevents mildew.
This includes running your air conditioning in the winter, which helps remove humidity and works well to defog the windshield.
2. Clean or change the air filter
Dirty cabin air filters prevent proper airflow. Check your filter often and clean or replace it.
3. Don’t pre-cool your car
Your car’s air conditioning operates at maximum efficiency when you’re driving, so don’t pre-cool your car. On extra hot days, put the fan on high once you start driving and open only the backseat windows for 10 to 20 seconds to force out the hot air.
4. Set AC to the coldest setting
Your car’s air conditioning is most efficient when set to the lowest temperature and adjusting the fan for comfort. Most air conditioning systems cool the air to 3-4 C. A higher temperature forces the system to re-heat the air, burning more fuel.
5. Keep your car clean
Dirt and debris can negatively impact your car’s air conditioning system. Keep it at bay by cleaning, dusting and vacuuming regularly. It also makes that cold air you’re breathing much more hygenic.
6. Don’t use AC on recirculate if you have back seat passengers
The recirculation mode pulls air from the front of the vehicle and re-cools it. It works well for passengers in the front of your vehicle, but can leave air stale and hot in the back.
