What Happens When You Call Us at 2 AM
We'll ask you a few quick questions: what the system is doing, what it's not doing, and whether there are any error codes on the thermostat or control board. That conversation usually takes three minutes and helps us show up with the right parts. We send you a confirmation, and when the technician is on the way, you get a text with their photo and live tracking. No guessing whether someone is actually coming. The technician confirms an arrival window when you call, typically within two hours depending on what's already on the schedule. For true emergencies, including no-heat situations during cold weather, we prioritize response as fast as conditions allow.

What an Emergency Furnace Repair Actually Costs
During the 2025-2026 heating season, Full Time completed 71 no-heat and low-heat furnace repair jobs, averaging $403.77 per repair including diagnostics, parts, and labor. Calls that came in after 5pm, on a weekend, or on a holiday averaged $523.77, reflecting the after-hours service fee that covers dispatching a technician outside normal business hours. These are real averages from completed jobs, not a sales estimate: a flame sensor or ignitor repair typically lands below that number, while a control board or inducer motor replacement runs above it. You'll get your exact price after the technician diagnoses your specific system, before any work starts.
Signs Your HVAC System Needs Emergency Attention
Details below
Not every HVAC problem is an emergency, but some are. Here's what warrants a call right now rather than waiting until Monday:
Gas Smell Near the Furnace
System Runs but Produces No Heat or Cooling
Burning Smell or Visible Smoke
Frozen Evaporator Coil or Outdoor Unit Ice
Carbon Monoxide Alarm with HVAC Running
Technician servicing a commercial packaged HVAC unit in the rain
How We Handle Emergency Diagnostics
When we arrive, we don't start the conversation by asking whether you've thought about a new system. We start with the equipment. A proper diagnostic means checking voltage at the board, confirming ignition sequence, testing the pressure switches, reading the fault codes, and inspecting the heat exchanger. It takes longer than a quick look-and-guess, but it's the only way to find the actual problem instead of throwing parts at it. We explain what we found in plain language before anything is approved. If the repair makes sense economically and gets you a reliable fix, that's what we recommend. If the system is genuinely at the end of its useful life, we'll tell you that too, and we'll show you why. Check out our why choose us page for more on how we approach every service call.

Furnace repair · Watertown
Our furnace started making a funny noise yesterday and needed to get checked out by a professional. Jason was here within the hour of my request for help. He had the furnace taken apart, part ordered and picked up, and the furnace put back together/up and running in less than 24 hours! Very knowledgeable, honest, and helpful too! We really appreciate the quick and kind assistance! Full Time Heating & Cooling will be our "go to" and our recommendation to others! GREAT job!

Furnace repair
Full time heating and cooling was great, and I will definitely use them again. I had an issue with my furnace, Jason made time for me the same day I called, diagnosed the issue and would have fixed it on the spot if he had the correct part. He fixed it early the next day, and it is running great. He also has very transparent and reasonable prices.

FAQ Common questions
Frequently Asked Questions
Answers below
What should I do while waiting for an emergency HVAC technician to arrive? +
For a no-heat situation, close off rooms you're not using to concentrate warmth and check that your thermostat is set to heat mode with the fan on auto. Don't try to bypass safety switches. If you smell gas, leave the house and call your utility before calling us. For a no-cooling situation, close blinds on sun-facing windows and avoid running heat-producing appliances. Don't run the AC if the outdoor unit is iced over.
How fast can you respond to an emergency HVAC call? +
Response time depends on how many calls are ahead of yours and how far you are from our service area in the Twin Cities west metro. The technician confirms an arrival window when you call, typically within two hours. For no-heat emergencies during extreme cold weather, we prioritize response. We won't give you a vague 'sometime today' answer. You'll know what to expect before we hang up.
Why does my furnace keep tripping off during cold snaps specifically? +
High-efficiency furnaces have a secondary heat exchanger that extracts additional heat from flue gases. In very cold weather, the condensate that exchanger produces can freeze in the drain line or the PVC flue pipe if it exits on the north or shaded side of the home. When the drain backs up, the float switch shuts the furnace off. It's a common winter pattern and usually a straightforward fix, though the underlying drain routing sometimes needs to be corrected to prevent recurrence.
Will an emergency HVAC call cost significantly more than a regular service call? +
After-hours and weekend emergency calls typically carry a higher service fee than standard daytime appointments. We're transparent about that before we dispatch. For reference, during the 2025-2026 heating season, Full Time's average furnace repair cost was $403.77 across 71 completed no-heat and low-heat jobs; emergency calls after 5pm, on a weekend, or on a holiday averaged $523.77. What we won't do is use emergency pricing as cover to inflate the repair itself. The part costs what it costs. The labor is what it is. You'll know the full estimate before work starts, and you're not obligated to proceed. We'd rather you make an informed decision than feel cornered.
Can a dirty air filter actually cause an emergency furnace failure? +
Yes, and it does more often than people expect. A heavily restricted filter forces the blower to work harder while reducing actual airflow across the heat exchanger. The heat exchanger overheats, the high-limit switch trips, and the furnace shuts off. If the limit switch fails from repeated tripping, you're looking at a repair that could have been avoided with a $10 filter change. We check filter condition on every call, emergency or otherwise.
What does HVAC stand for, and what systems are covered under emergency service? +
HVAC stands for Heating, Ventilation, and Air Conditioning. Our emergency service covers gas furnaces, central air conditioners, heat pumps, and the thermostats and controls that connect them. We also handle urgent gas fireplace services when a fireplace used for supplemental heat stops working. Boilers, ductless mini splits, and indoor air quality equipment are also within scope. If it moves air or controls temperature in your home, we can diagnose it.
