Signs You Need Emergency Heating Repair

Don't Wait It Out — These Situations Call for Help Tonight

Some heating problems can hold until morning. These can't. If you're experiencing any of the following, call us now at 833-539-9153.

  • Complete Loss of Heat

    If your furnace isn't producing any heat and indoor temps are dropping — especially with children, elderly family members, or pets in the home — this is an emergency. Call immediately.

  • Gas Smell Near Your Furnace

    A rotten-egg smell near your furnace or gas line means a potential gas leak. Leave the house, don't flip any switches, and call your gas provider and us right away.

  • Carbon Monoxide Alarm Triggered

    A CO alarm going off near your furnace is a serious warning. Evacuate, get fresh air, and call for emergency service before returning indoors.

  • Unusual Sounds or Burning Smell

    Banging, screeching, or a burning odor coming from your heating system can signal a failing motor, cracked heat exchanger, or electrical fault — all of which need same-night attention.

What We Fix on Emergency Calls

Comprehensive Emergency Furnace Repair — Any Brand, Any Fuel

Our technicians are trained on gas, electric, and dual-fuel systems from every major manufacturer. Here's what we handle on emergency calls:

  • Igniter and Flame Sensor Failures A faulty igniter or dirty flame sensor is one of the most common reasons a furnace won't light. We carry replacement parts for the most popular models and can usually have your heat restored within the hour.
  • Blower Motor and Capacitor Issues If your furnace runs but no air comes through the vents, the blower motor or start capacitor may have failed. We diagnose and replace these on the spot.
  • Control Board and Thermostat Problems A failed control board or miscommunicating thermostat can shut your entire system down. We test both components and replace as needed to restore normal operation.
  • Heat Exchanger and Limit Switch Faults A tripped high-limit switch often indicates a deeper issue like a cracked heat exchanger or airflow restriction. We identify the root cause — not just reset the switch — so the problem doesn't come back.

4/4/2024 My Carrier furnace was reflecting an error code. I contemplated calling a furnace company that was offering a great deal for first time clients. I contacted Done Plumbing and Heating instead since they have done all my other plumbing needs as well as initially installing my Carrier furnace and air conditioner. I am so thankful I did contact Done. Jay Mitchell came out within hours of my call for service. He diagnosed the problems and then went over and beyond by verifying my warranty with Carrier for the replacement of the necessary part. He took the time to verify the labor warranty reflecting on my paperwork should have reflected 10 years not 1 year and ensure me that the part and labor were all covered. He was knowledgeable enough to catch the error on warranty coverage on the labor on my paperwork which someone with less experience would not have. He was professional, personable, and kind enough to answer all my questions. He returned early the next day with the replacement part, installed the part, and completed a diagnostic check to confirm all was well with my furnace. He made me feel very valued as a Done customer and reflected kindness in answering all my questions. He gets a 5-star rating with me and he is an asset to Done as an employee. He cemented my commitment to use Done for any needs I have for any repairs or replacements that they can provide in the future. Thank you so much Jay. You certainly made my year and saved me a ton of money by verifying my warranty.

Chad was awesome he reconfigured the pipe exiting the house for the sump pump so it didn’t drain on the sidewalk and added a coupling so I could remove the pipe when I mowed. He understood what I said and his people skills were fantastic. Chad was back to repair the outside spigot on 5/11/2022. Once again he provided a 5 star service. 4/27/23 garbage disposal service was awesome. Quick and cheap. Service providers gave me great info to keep my disposal clean and operating smoothly. As usual Done got it done

Prompt service, no hidden commuter charges, prices quoted on site following inspections. Justin snaked a clogged sewer line successfully. Jeremy (and Austin) assessing the cause of the back up were excellent in estimating further repairs.

Ben on the HVAC side of Done Plumbing & Heating did an outstanding job addressing a host of immediate and persistent issues with our furnace. The series of issues took a few days to resolve, such as compensating us for a wrong part being installed in our furnace by a peer, installing the correct parts, and diagnosing a persistent short cycling problem as due to a thick coat of dust and dog hair build up in A/C coil area that tripped the high limit. It was curious that: (a) I don't own pets since at this residence, and; (b) the company I'd employed for 3 years to "maintain and clean" my furnace didn't catch it during "annual service." Yet, Ben caught it and removed what was a sizeable mound caking/choking the furnace and over working the blowers within an hour of one day... Need I say more! And, is the other company in trouble?!

Today, Neil came to troubleshoot the cause of a loud water heater motor and probably solved the issue with a tank flushing. Plus, he provided comprehensive explanations and quotes for replacement/installation.

Nov 2017 - Once again we called Done for help. Thanks so much for the 3 crews that worked on our plumbing and heating problems. They were prompt, courteous, professional and worked hard on all the issues, advising what was going on each step of the way. They were a pleasure to work with. Gavin and Jacob came initially for preventive maintenance on our corroded kitchen pipes and to fix a leaking bathroom faucet. They also assessed a sewer problem and spotted a leak coming from the furnace. Jason and Jacob corrected the sewer line problem the next day. We appreciated Jason’s work attitude and ethic (so sincere) as well as his sense of humor. Thomas fixed the leak in the furnace and prevented a major problem down the road.

We discovered our backed up drain on 12/30/16. Lincoln came the next morning, determined the problem and fixed it so we could get the rest of it cleaned up. He was professional and personable, knew what he was doing. What a way to start a new year, but we were glad Done came to our rescue.

December 2, 2022 - Vincent came out and was done in about an hour to clear out sewer lines for preventive maintenance. He inspected 4 toilets and found the access to the sewer line in the furnace room. He removed and then replaced tables, chairs and other items that were blocking the access. After he was done, he moved everything back into place. He was friendly and helpful. It was a pleasure to work with him.

Frequently Asked Questions

How fast can you get to my home for an emergency heating repair?

Response times vary by demand and your location within the Denver metro, but we prioritize emergency no-heat calls — especially overnight and in extreme cold. When you call 833-539-9153, we’ll give you an honest estimated arrival window right away. We never leave you guessing.

Is the after-hours emergency rate much higher than a daytime call?

There is a service fee for emergency after-hours calls, and we’ll be upfront about it before we dispatch. All repair pricing is quoted before any work starts so you can make an informed decision. Many homeowners find the cost of a same-night fix far preferable to a cold house for another 12 hours.

My furnace keeps shutting off after a few minutes — is that an emergency?

It can be. Short-cycling (turning on and off rapidly) is often caused by a dirty flame sensor, an overheating heat exchanger, or a failing control board. If your home temperature is dropping and you can’t get it to run consistently, treat it as an emergency and call us. Ignoring a cracked heat exchanger in particular can create a carbon monoxide hazard.

Do you work on all furnace brands?

Yes. Our technicians are experienced with all major brands including Carrier, Trane, Lennox, Rheem, Bryant, Goodman, American Standard, and many others. We carry a wide selection of common parts on our trucks and can source less common components quickly to get your system running again.

*Offers cannot be combined with other promotions or applied to dispatch fees. No cash value. Must present offer at time of service. Call for details.
