Your vehicle's air conditioning system needs to be routinely maintained by trained technicians in order to operate efficiently and keep you cool during our short, but hot, Vermont summers. The function of an air conditioner is to help remove heat and humidity from inside the passenger compartment of the vehicle. Powered by a belt, the air conditioning compressor compresses the refrigerant to pressurize it and pump it through the system. The refrigerant is pushed through a valve where pressure and temperature are reduced.
