Air Conditioning Preventive Maintenance Checklist

You wouldn’t drive your car 100,000 miles without changing the oil. The same logic holds true for your home comfort system. Regular A/C preventive maintenance is the best way to ensure trouble-free operation and peak performance. Annual maintenance is also important, and should be done in the spring. It can help to avoid a system failure in severe hot weather when you need it most, and it can also keep your energy bill from getting out of control.
