Maintaining Your Porsche’s HVAC System: Service Tips
Driving in our sweltering Arizona climate is no fun at all without air conditioning.

Keeping this vital vehicle component in good shape is relatively easy; just follow the Porsche HVAC maintenance guidelines laid out below. And our technicians can fully service your AC once a year to ensure it keeps you cool over the long run.
Maintaining Your Porsche’s HVAC System: 7 Service Tips
Park Out of Direct Sunlight
As with any vehicle component, you’ll preserve your AC for longer if you avoid unnecessary overuse. Parking your car in a garage or at least under shade reduces how warm the cabin gets. This means you won’t need to run your AC as much to get comfortable each time you drive.
Change the Air Filter Frequently
The cabin air filter prevents airborne debris from entering the system as air flows in through the AC. In Arizona, the air can get quite dusty at times, which puts the filter under excess strain. Inspect your cabin filter often and install a replacement whenever it seems clogged or dirty, which might be once or twice a year.
Run Defrost Mode Weekly
Moisture can build up inside any car’s AC, creating a risk of mold and mildew, which sends toxic spores into the air you breathe and might gradually clog up the system. To combat this, you can run the defrost mode once a week to dehumidify the air and reduce moisture. Also, try not to leave your car unused for prolonged periods.
Flush the Refrigerant
Refrigerant is the substance that circulates throughout the AC system, transforming back and forth between gas and liquid form, absorbing heat as it does. This refrigerant is long-lasting but still needs to be flushed occasionally.
Watch Out for Refrigerant Leaks
If the refrigerant leaks, your AC will stop blowing cold air. It’s often difficult to identify the source of a refrigerant leak, as this substance is transparent and evaporates quickly when exposed to air. One of our technicians can inject a special dye into the AC lines which allows us to see and repair any leaks.
Promptly Repair HVAC Faults
If your AC starts making strange sounds or malfunctions in any way, the sooner you have it repaired, the better. When faults are allowed to develop, they only worsen, causing more long-term harm to the HVAC and car.
