The most common cause of a malfunctioning air conditioning unit is a low level of refrigerant. This could be caused by a leak somewhere in the system. Since modern air conditioning systems are complicated, it's best to have a trained Automotive Technician at Pete's Auto Repair in Ferndale check out the problem. The air conditioning maintenance industry has changed a lot since 1994, when the Federal government outlawed the use of a refrigerant called R-12, known by its brand name Freon. In the past, if your air conditioner wasn't blowing cool air, you'd head down to the service shop, they'd top your car off with a little Freon and you'd be on your way.
Fantastic service every time. Thanks for all that you do!
