During a heating maintenance visit, our certified technicians perform a comprehensive 20+ point inspection and tune-up that includes: cleaning burners and heat exchangers, checking electrical connections and components, lubricating moving parts, testing safety controls, inspecting gas/oil connections, calibrating thermostat settings, examining ductwork connections, checking blower components, replacing standard filters, and testing system operation through a complete cycle. This thorough approach ensures every aspect of your heating system is operating safely and efficiently before Houston’s cooler weather arrives.
