When a Furnace Problem Is a Real Emergency
In Sioux Falls, an unheated home can drop below freezing overnight during a cold snap, putting plumbing at risk and making the house genuinely unsafe for small children, older adults, and pets. That is why we treat complete loss of heat as an emergency rather than a next-available appointment.
Some symptoms mean you should shut the system down and call immediately rather than waiting for morning.
- You smell gas — leave the house first, then call your gas utility, then call us.
- A carbon monoxide alarm has sounded: get everyone outside and call 911 before service.
- There is no heat at all and the outdoor temperature is below freezing.
- The furnace makes a loud boom on start-up, which can indicate delayed ignition.
- You see scorching, soot, or smell a persistent burning odor around the furnace cabinet.
What to Do While You Wait for the Technician
- Set the thermostat to heat and raise the setpoint a few degrees so the system attempts a call for heat when power is restored.
- Check that the furnace power switch is on and the breaker has not tripped.
- Open cabinet doors under sinks on exterior walls to slow pipe freezing.
- Close off unused rooms and keep exterior doors shut to hold heat in living areas.
- Never run a gas range, grill, or unvented fuel heater indoors for warmth.
Common After-Hours Failures in Sioux Falls Homes
- Flame sensor lockout after the burner lights and shuts down within seconds.
- Cracked hot surface ignitor that will not glow, so the gas valve never opens.
- Pressure switch fault from a snow-blocked intake or exhaust pipe.
- Frozen or plugged condensate drain on a high-efficiency furnace.
- Failed draft inducer or blower motor after heavy continuous runtime.
- Tripped high-limit switch caused by a clogged filter restricting airflow.
Emergency Repair Costs
After-hours labor rates are higher than business-hours rates. That is standard across the industry, and we tell you before dispatch rather than at the door. What does not change is the approach: diagnose first, quote second, repair after you approve.
If you want a planning range before you call, our furnace repair cost calculator lets you set the problem type, furnace age, and after-hours timing to see a realistic estimate.

Frequently Asked Questions
Do you really answer calls at night?+
Yes. Residential no-heat calls are taken 24/7, including nights, weekends, and holidays. Have your 5-digit ZIP code ready so we can confirm service availability for your address.
What should I do if my furnace stops working at night?+
Check the furnace switch, breaker, thermostat batteries, and filter first. If the furnace still will not run, call 605-800-7431. Keep interior doors open, avoid unvented heaters, and protect plumbing on exterior walls while you wait.
Is emergency furnace repair more expensive?+
After-hours labor rates are higher than daytime rates. The diagnostic approach and parts pricing stay the same, and you approve the total before the repair is performed.
Can you help if the problem is a gas leak?+
If you smell gas, leave the home immediately and call your gas utility from outside. We can repair the furnace after the gas emergency is cleared — safety comes before any service call.
Do you take emergency calls outside Sioux Falls?+
Yes, for residential homes in nearby communities including Brandon, Harrisburg, Tea, Hartford, Dell Rapids, Baltic, Crooks, Lennox, Canton, and Worthing.
