Air conditioning does more than just cool your car in the hot summer months. It pulls moisture from the air inside your car during humid, rainy weather and helps your car’s heater defrost your windows in the frosty winter months. The air conditioning system in your car loses about 5% of its efficiency every year, so even in normal conditions; it will slowly become less effective. For knowledgeable, reliable auto air conditioning repairs in the Inland Empire, trust your car to the experienced staff of George’s Sierra Shell.
