A furnace repair call in Concord is usually a no-heat call. Older downtown wood-frame and brick buildings still include steam and hot water. Outer streets mix capes, colonials, and oil-fired forced air. A finished attic is often the room that never quite heats. Say whether you smell gas, see soot, or the blower runs with cold air. If you smell gas, leave and use the utility emergency number. Otherwise call (603) 420-0791 with the ZIP. Liberty Utilities lists Concord for natural gas. The main does not enter every road in 03301 or 03303. Off the main, propane and oil are ordinary. Read the electric bill instead of guessing the utility. The fuel decides who is licensed to open the burner. Basements are often low. A high-efficiency furnace that needs a plastic vent and a condensate drain is a different job from a cabinet on the old flue, especially when a water heater shares the chimney. Ask what the quote includes if the heat exchanger or the vent is the problem. Confirm license and insurance before work starts.
