Maintenance Service

Our summer checkups include cleaning out AC drains and the outdoor coil as well as checking safeties, refrigerant levels, and electrical components. For winter checkups, we service and clean the burner assemblies, make sure the controls are working, and oil the motors where necessary. Both checkups include a diagnostic check of the equipment and a 15-point seasonal check. We advise you of any parts that are no longer operational or that look like they are on the way out shortly. We carry most parts on the truck, so we can replace nearly anything that you approve.

Routine Maintenance Service Policies

Our maintenance service policies are a great investment to prevent a system breakdown at the worst possible time, like in the middle of summer or winter. For a fixed price, we come out once in the spring and again in the fall to check out your unit (AC in the spring and furnace in the fall), make sure everything is operating properly, and clean it. If you need to have any parts replaced, you get a 10% discount on them. We call these policies Peak Performance Service Contracts.
