Furnace Repair in Cherry Hills Village

On furnaces 15 to 25 years old, we most often find cracked hot surface igniters, dirty flame sensors, failing inducer motors, weak blower capacitors and limit switches tripping because of restricted airflow. Big homes with long return runs are especially sensitive to clogged filters and closed registers.

Altitude is a factor too. Manufacturers require gas input to drop about 4 percent per 1,000 feet above sea level once installed above 2,000 feet, which at about 5,423 feet works out to roughly 22 percent. A furnace that was never set up for altitude can overheat its heat exchanger and produce carbon monoxide, so we verify gas pressure and temperature rise on every call.

Every visit begins with a carbon monoxide and combustion safety test. Then we pull fault codes, test ignition, flame sensing, the inducer and pressure switch, measure gas pressure and temperature rise, and inspect venting, the condensate system and the blower. In zoned homes we cycle each zone to confirm dampers respond.

You see the diagnosis and the flat-rate price before we start. The diagnostic is free when you go ahead with the repair, and we don't charge overtime for nights or weekends. Our trucks are stocked for Trane, Lennox, Carrier, Goodman, Bryant and Rheem equipment.

A replacement furnace in Cherry Hills Village needs a permit from the city's Building Division, applied for through its online portal; HVAC work can be included on the main permit when it's part of a larger remodel. The city does not license contractors, but electrical contractors must register with it.

Xcel Energy supplies gas and electricity under the city's franchise. Xcel has offered rebates for furnaces rated 95 percent AFUE or higher that replace a non-condensing furnace when installed by a participating contractor; confirm current terms before buying. We usually recommend repair while the heat exchanger is sound, and replacement when it is cracked, when an older unit needs major parts repeatedly, or when one zone has never kept up.
