A furnace tune-up covers the combustion process, heat exchanger inspection, venting and gas-pressure checks, burner and ignition service, filter replacement, and safety-control testing. For oil systems we also service the nozzle, filter and pump.
Annual service keeps your warranty valid, your bills lower, and — most importantly — catches cracked heat exchangers and venting problems before they become carbon-monoxide risks. Thinking about replacing an aging furnace? Ask us for the heat pump comparison — that's where the rebate money is now.
