Car Care - About Climate Control

Your 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.


What to Watch For

Your air conditioning system has components that require internal lubrication (provided by periodic A/C system operation) to avoid drying out and cracking, which can lead to system leaks. Running your air conditioner regularly — even during winter months — helps lubricate these components and is recommended for many vehicles. However, some newer models eliminate the need for this. We recommend that you consult your owner's manual or visit our technician to get the right information for your vehicle.
