Furnace Repair in Brighton

At about 4,987 feet, the air here has noticeably less oxygen than at sea level. Gas furnaces have to be set up for this, using the manufacturer's high-altitude derating or orifice changes. When a unit was never adjusted, or a replacement gas valve was set to factory defaults, it can over-fire, run lean, soot up or trip its rollout switch. We check gas pressure and temperature rise against the nameplate on every repair, not just on installs.

The open, flat terrain also means wind. Wind-driven cold air finds every gap around rim joists and attic hatches, so the furnace runs longer cycles during a cold front. Long run times wear blower motors faster, and high-efficiency furnaces that vent through the side wall can have their intake or exhaust pipes blocked by drifting snow, which locks the unit out on a pressure-switch fault.

We start by reading the error code and confirming the sequence of operation: thermostat call, inducer start, pressure switch close, ignition, flame proof and blower. Most no-heat calls in newer homes trace to one step in that chain, and finding the exact one keeps you from paying for parts you don't need.

Next we measure what matters for safety and efficiency: combustion readings and ambient CO, gas pressure, temperature rise across the heat exchanger, static pressure in the duct system and the condition of the condensate drain on 90%+ units. Frozen or clogged condensate lines are a frequent winter problem in basements and garages here.

You get a flat-rate price before any work begins, with no overtime charges. The diagnostic is free when you go ahead with the repair. Our trucks carry common ignitors, sensors, inducers, switches and boards for Trane, Lennox, Carrier, Goodman, Bryant and Rheem, so many repairs are finished on the first visit.

If your furnace is under about 15 years old and the problem is a single component, repair is usually the right call. Once a builder-grade unit passes 18 to 20 years and needs a major part like an inducer motor or a control board, or shows any sign of a cracked heat exchanger, replacement starts to make more sense. We show you the readings and the part condition so you can decide.

If you replace, it's a good time to correct sizing and return-air problems that were built in from the start. The city requires a building permit for heating system replacements through the city's Community Development department. For a true no-heat emergency, the city allows the furnace to be replaced first, as long as the permit is applied for by the next business day and the work is left uncovered for inspection. The city lists United Power for electricity and Xcel Energy for natural gas, so check Xcel's current rebates before you choose new equipment.
