Furnace Repair in Northglenn

Northglenn sits at roughly 5,364 feet. Gas furnaces at this elevation must be set up for altitude, with proper orifices and gas pressure. An incorrectly set furnace runs rich, soots, and can produce carbon monoxide. We measure gas pressure and check the flame on every furnace call.

The city's record low is minus 24 degrees, set in December 1990, and the area averages around 45 inches of snow a year. Those deep cold periods are when a marginal furnace fails, usually from a weak igniter, a tired inducer motor or a blower capacitor that can no longer start the motor. Snow can also bury side-wall vents on high-efficiency units, so keep the intake and exhaust pipes clear after a storm.

Our technician checks the fault code, then works through the sequence: thermostat call, inducer, pressure switch, ignition, flame proving and blower. We test each part with a meter instead of swapping parts on a guess. We also measure temperature rise and duct static pressure, because in older homes here an airflow restriction is often the root cause behind a failed part.

A carbon monoxide and combustion safety test is part of every furnace visit. The diagnostic is free when you go ahead with the repair, we quote a flat price before starting, and there is no overtime charge for after-hours calls. Our trucks are stocked for Trane, Lennox, Carrier, Goodman, Bryant and Rheem.

If your furnace is under 15 years old and the problem is a single part, repair it. If it is 20 years or older, has a cracked heat exchanger, or fails repeatedly because the ductwork cannot move enough air, replacement deserves a look. In a 1960s house, a replacement quote should include a duct and return evaluation and a plan for venting the water heater properly. Without those, a new furnace inherits the old problems.

Northglenn's Building Division, located at City Hall with building services provided by SAFEbuilt, issues permits and schedules inspections. The city requires any hired contractor to be licensed with the city and to obtain all required permits and inspections. Furnace repairs do not need a permit; ask the Building Division about specific replacement work.

Northglenn's resident guide lists Xcel Energy for electricity and heat. If you are considering a heat pump instead of another gas furnace, check Xcel's current rebates and the regional Power Ahead Colorado heat pump program before you decide.
