We'll evaluate your existing electric panel's capacity, wiring, and circuit breakers to ensure it can safely support the new system's power demands.

Our preventative HVAC maintenance in Maryville includes cleaning critical components, checking electrical connections, lubricating moving parts, testing system controls, and inspecting the blower assembly. For the blower motor specifically, we check for proper operation, listen for unusual noises indicating bearing wear, and ensure it's clean and receiving correct voltage. This regular care can identify small issues—like a worn belt or dirty motor—before they lead to a complete blower motor failure, saving you from an unexpected breakdown during extreme weather.
