Furnace Repair in Littleton

Littleton has a real stock of mid-century architecture, including Rangeview, built from 1953 on larger lots off South Windermere, and Arapaho Hills, a modernist neighborhood now listed on the National Register of Historic Places. Homes like these were often designed around compact mechanical spaces and unusual floor plans, and later furnace replacements were squeezed in wherever they fit. We check clearances, venting, and combustion air on every one, because a furnace that fits physically is not always installed safely.

We run a carbon monoxide and combustion safety test before closing up any furnace we touch. Littleton sits around 5,400 feet, high enough that manufacturers require gas input to be derated roughly 4 percent per 1,000 feet of elevation. An unconverted or mis-converted furnace can overfire, and we verify the gas pressure and orifice setup as part of the diagnosis.

We read fault codes, measure temperature rise, test static pressure, and inspect the heat exchanger, flue, and burners. Then we give you an upfront flat-rate price for the fix. The diagnostic is free when you approve the repair, and there are no overtime fees, including for 24/7 emergency calls. Our trucks are stocked for the common failures on Trane, Lennox, Carrier, Goodman, Bryant, Rheem, and other major brands, so most repairs are finished in one visit. If a technician is nearby, same-day service is likely.

Repairs do not need a permit, but replacements do. The city's residential permit guide lists furnaces, air-conditioning equipment, ventilation systems, and ductwork as work that generally requires a permit and inspection, and that includes replacing equipment. Here is the catch: many homes with a Littleton mailing address are not in the city at all. Ken Caryl, Columbine, Highlands Ranch, and Roxborough Park are unincorporated communities, so permits there go through the county rather than the City of Littleton.

Xcel Energy supplies both gas and electricity inside the city. Xcel's rebate for a 95 percent AFUE or higher furnace applies when it replaces a non-condensing furnace and the work is done by a participating contractor.

If the furnace is under about 15 years old and the problem is a part like an igniter, inducer, or control board, repair it. If it is over 20, has a cracked heat exchanger, or keeps tripping limits because the ductwork cannot move enough air, replacing only the furnace may not fix the comfort problem. In those homes we will tell you whether duct changes need to be part of the plan before you spend money on new equipment.
