Furnace Repair in Aurora

The city sits at about 5,471 feet at its posted elevation, ranging from roughly 5,285 feet along Sand Creek to over 6,200 feet at the Douglas County line. Gas furnaces are typically derated about 4% per 1,000 feet of elevation, so a furnace that was not set up for altitude, or one with the wrong orifices from a previous install, can burn rich, soot up and produce carbon monoxide. Checking gas pressure and burner setup against the manufacturer's high-altitude table is part of how we diagnose short-cycling or sooting units.

Average December and January lows sit in the upper teens, and the city has recorded lows of -32°F. A furnace that limps through October can quit on the first real cold snap, which is why we see many calls for weak igniters and dirty flame sensors in early winter.

We start with the basics that cause a surprising share of calls: thermostat settings, filter condition, the furnace door safety switch and the gas valve. Then we read the control board's fault codes, measure gas pressure, test the igniter, flame sensor and pressure switches, and check temperature rise across the heat exchanger. Every furnace visit includes a carbon monoxide and combustion safety test.

You get a flat-rate price before any work begins, with no overtime fees for nights or weekends. The diagnostic is free when you approve the repair. Our trucks carry common parts for Trane, Lennox, Carrier, Goodman, Bryant and Rheem equipment, so most igniter, sensor, inducer and blower repairs are finished on the first visit. Same-day appointments are available when the schedule allows, and emergency service runs 24/7.

A single failed igniter or capacitor on a 12-year-old furnace in a Saddle Rock basement is a repair. A cracked heat exchanger, repeated control-board failures, or a 25-year-old unit in a 1970s home that already needs an inducer motor usually points toward replacement. In older homes, replacement is also the moment to fix the airflow problems that wore out the last furnace.

Replacing a furnace here requires a permit from the City of Aurora Building Division, applied for through the city's online permit portal, followed by inspection. Xcel Energy provides gas and electric service across the city, so Xcel's current rebate rules for heating equipment and heat pumps are the ones to check before you choose a replacement.
