If your vehicle creates an unusual amount of noise during heat or cooling, produces an abnormal odor, or blows stale, unconditioned, air you should see a technician. During your AC diagnostic, we will inspect your entire heating and cooling system. This includes checking belts for cracks, the compressor for leaks, the cooler system, the blower fan/motor as well as electrical components (such as thermostat) for connectivity. We will also test the entire system for low pressure and if needed we may evacuate and recharge your system with refrigerant according to your vehicle’s manufacturer’s specifications.
