Yes. Done offers emergency furnace repair for Front Range homeowners who lose heat when temperatures drop. Colorado winters are unforgiving — a furnace that quits during a cold snap can make a home unsafe within hours, especially for young children, older adults, or anyone with health concerns. Done’s team is available for urgent heating calls because heat is not optional in Denver.

What Qualifies as a Heating Emergency?

Any complete loss of heat during cold weather is a legitimate emergency, but there are specific situations that need immediate attention. If your furnace is producing no heat at all and outdoor temperatures are below freezing, call right away — pipes in exterior walls and crawlspaces can freeze and burst within hours. A furnace that is running but not heating adequately, one that is producing strange burning smells, or one that is tripping your CO detector also warrants an emergency call rather than waiting for a routine appointment slot.

Colorado’s Climate Makes Fast Response Critical

Denver and the surrounding Front Range experience dramatic temperature swings — it is not uncommon for overnight lows to dip into the single digits even in October or April, well outside what most people think of as “winter.” At 5,280 feet, wind chill adds to the exposure risk. The region also sees fast-moving cold fronts that can drop temperatures 40 degrees in a matter of hours. That is not the time to wait several days for a service call. When you call Done for an emergency furnace repair, a dispatcher works to get a technician to your home as quickly as possible with the parts and tools needed to restore heat in a single visit whenever possible.

What to Do While You Wait for the Technician

While you wait, take a few steps to keep your household safe and reduce pipe-freeze risk. Close off rooms you are not using to concentrate warmth. Use electric space heaters in occupied rooms — but never use a gas oven, grill, or generator indoors for heat, as those produce carbon monoxide. Open cabinet doors under sinks on exterior walls to allow warmer air to reach the pipes. If you have a CO detector and it is sounding, leave the house immediately and call 911 before calling for furnace service.

Common Causes of Sudden Furnace Failure

In Done’s experience, sudden no-heat calls most often come down to a handful of causes: a failed ignitor (the part that lights the burner), a tripped high-limit switch triggered by a clogged filter, a failed inducer motor, a faulty pressure switch, or a gas valve issue. Done’s technicians carry common replacement parts on their trucks so that many emergency repairs can be completed the same day. More complex issues — like a cracked heat exchanger — may require a follow-up appointment or a conversation about replacement options if the furnace is older and not worth repairing.

  • Failed ignitor — very common, usually replaceable same visit
  • Clogged filter tripping the high-limit safety switch
  • Faulty pressure switch or inducer motor
  • Gas valve failure
  • Cracked heat exchanger — safety concern requiring honest assessment

Preventing the Next Emergency

The best emergency is the one that never happens. Done’s Care Club maintenance membership includes a professional furnace tune-up each fall that catches worn parts, dirty components, and early warning signs before they become a no-heat call in January. Members also receive priority scheduling, which means shorter waits even during the busiest cold snaps.

If your heat is out right now, visit our emergency heating repair page or call Done directly. For non-urgent issues, you can also schedule through our standard furnace repair service page. When you call, share whatever details you observed — the error code on the LED, any unusual sounds or smells, and how long the system has been unresponsive. That information helps the technician arrive with the right parts and gives you the best chance of having heat restored in a single visit.
