Furnace & Heating Repair in Denver, CO
Honestly, most furnace & heating repair questions can be answered over the phone. Save yourself the dispatch fee — call first, ask second. If we can't get to you ourselves, we'll tell you who to call. Free consult either way.
What's typical for this job
Heating-side repairs run different than AC. Most furnace calls come down to ignitor failure, flame sensor, control board, or pressure switch. Heat pumps add reversing valve and defrost board.
Gas furnace ignitor failures are the most common winter call — about 40% of no-heat calls. The ignitor is a $35 part and a 20-minute job; total flat-rate runs $185-$340.
Heat pump no-heat in cold weather usually means failed reversing valve solenoid (system stuck in cool mode) or failed defrost board (outdoor coil iced up). Both diagnoseable in under an hour.
Older furnaces (15+ years) develop heat exchanger cracks. We check for them every diagnostic visit because a cracked heat exchanger leaks carbon monoxide and is a replacement-not-repair issue.

From the books — a recent Denver job
Property manager call, Denver-area duplex. Both units had furnace clicking but not igniting. We pulled the system apart and found failed hot surface ignitor. Replaced ignitor, system back online in 30 minutes on the same trip — both tenants happy. $340.
