Your car's air conditioning (A/C) system is divided into two sides, known as the high side and the low side. The compressor, beginning at the high side, functions like a pump, moving refrigerant through the system. The expansion valve, which begins at the low side, restricts refrigerant flow, lowering the pressure and the temperature of the refrigerant.

Car A/C systems have components that require love and attention to avoid drying out and cracking. The car heater also needs regular check-ups to make sure there are no leaky valves or blockages. Let Penners Auto service your car A/C or car heater to keep you comfortable at any temperature.
