Air conditioning should be check at least twice a year.  When we check it we are looking for performance, we make sure it isn’t leaking and that the refrigerant and oil located in the system is full.  It’s recommended that the system should be flushed every other year. With Air Conditioning preventive work is highly recommended because a failure is the third most expensive cost of repairs on a car. We are your Simi Valley Air Conditioning Repair Shop.
