We highly recommend an annual service tune-up and cleaning for your furnace. Typically the optimum time of year to perform the maintenance is the fall, before you fire up your furnace for the cold weather. The purpose of the service tune-up is to keep your system running at top efficiency throughout the season, so you have heat whenever you need it. Our experienced technician will clean and check all the connections, controls, sensors, drains, motors, ducts, valves, and blowers, as well as your ignition assembly, thermostat(s), and smoke and carbon-monoxide detectors.
