Symptoms
Common Signs Your Furnace Needs Repair
Furnaces rarely fail without warning. These are the patterns Sioux Falls homeowners notice first — and each one links to a page explaining the cause and the fix.
No heat at all
Thermostat is calling, the house keeps dropping, and the burner never fires.
Read more →Cold air from the vents
The blower runs but the air never warms — often a flame sensor or ignitor.
Read more →Turning on and off
Two-to-five-minute cycles in cold weather signal airflow or safety trips.
Read more →Completely unresponsive
No blower, no click, no display response from the furnace at all.
Read more →Three tries then lockout
A cracked hot surface ignitor stops the burner from lighting.
Read more →Thermostat acting up
Blank screens, ignored schedules, and Wi-Fi thermostats without a C-wire.

No Heat? What Homeowners Should Check First
These five checks take about two minutes and resolve a real share of no-heat calls. If heat does not return, call us and we will take it from there.
- Thermostat is set to HEAT, the setpoint is above room temperature, and the batteries are fresh.
- The furnace service switch on the wall beside the unit is switched on.
- The furnace breaker has not tripped — reset it once, but only once.
- The air filter is clean; a packed filter can overheat the furnace and trip a safety.
- The blower door panel is fully seated against its safety switch.

Repair vs. Replace Guidance
An aging furnace does not automatically need replacing, and a big repair bill does not automatically mean a new system is smarter. We use a simple framework with homeowners:
- Under 12 years old: repair is almost always the right call.
- 12 to 20 years: weigh the repair cost against remaining life and failure frequency.
- Over 20 years with a major component failure: replacement deserves a serious look.
- Any cracked heat exchanger or combustion safety issue: stop and address safety first.

Know Your System
Inside Your Furnace: The Parts That Fail
Understanding the basic sequence makes any repair conversation easier. Your thermostat calls for heat, the draft inducer starts and proves the pressure switch, the ignitor glows, the gas valve opens, the flame sensor confirms flame, and the blower sends warm air to your rooms.
- Ignitor: glows to light the burners — brittle and a frequent failure point.
- Flame sensor: proves flame within seconds or the gas valve closes.
- Heat exchanger: transfers heat to your air without mixing combustion gases.
- Draft inducer: pulls exhaust through the exchanger and out the flue.
- Blower motor: circulates heated air through your ductwork.
- Air filter: protects the blower and keeps airflow within safe limits.

Local Context
Why Sioux Falls Homeowners Need Reliable Winter Heating
Sioux Falls winters put more runtime on a furnace than most of the country ever sees. Sub-zero nights, sustained wind chill off open prairie, and a heating season that stretches from October into April mean your furnace may run tens of thousands of cycles in a single year.
That runtime is exactly why ignitors crack, flame sensors foul, capacitors weaken, and inducer bearings wear out here faster than in milder climates. It is also why a small, ignored symptom in November so often becomes a 2 a.m. no-heat call in January.
When the heat fails during a cold snap, an unheated house can approach freezing indoors overnight, putting plumbing and occupants at risk. We treat those calls with the urgency they deserve.

Frequently Asked Questions
Straight answers to what Sioux Falls homeowners ask most about residential furnace repair.
How much does furnace repair cost in Sioux Falls?+
Most residential furnace repairs in the Sioux Falls area fall within a wide range depending on the failed part, the age of the system, and whether the visit is after hours. Small ignition repairs such as a flame sensor sit at the low end, while blower motors, gas valves, and inducer assemblies sit at the high end. Use our furnace repair cost calculator for a planning range, then call 605-800-7431 for a free quote.
Do you offer 24/7 furnace repair?+
Yes. We take residential no-heat calls around the clock, including nights, weekends, and holidays. Have your 5-digit ZIP code ready when you call so we can confirm service availability for your address.
What should I do if my furnace stops working at night?+
Check the thermostat mode and batteries, the furnace power switch, the breaker, and the air filter. If the furnace still will not run, call 605-800-7431. While you wait, keep exterior doors closed, open cabinet doors under sinks on exterior walls to protect plumbing, and never use a gas range or unvented heater for warmth.
Why is my furnace blowing cold air?+
The most common causes are a dirty flame sensor shutting the burner down seconds after ignition, a failed hot surface ignitor, a thermostat fan setting left on ON instead of AUTO, or a clogged filter causing the high-limit switch to trip.
How do I know if I should repair or replace my furnace?+
Consider age, the cost of the repair relative to replacement, how many times it has failed recently, and how long you plan to stay in the home. Any safety issue such as a cracked heat exchanger overrides the cost comparison. We give you the diagnosis and options with no pressure either way.
Can you repair older residential furnaces?+
Yes, as long as replacement parts are available and the system can operate safely. We regularly repair older gas and electric furnaces in Sioux Falls homes and will tell you honestly when a system has reached the end of practical repair.
Do you service gas furnaces?+
Yes. We service residential natural gas, propane, and electric furnaces, including standard-efficiency, high-efficiency condensing, and modulating variable-speed systems.
What furnace brands do you work on?+
We work on most common residential brands, including Carrier, Trane, Lennox, Goodman, Rheem, York, and Amana. We are not affiliated with or endorsed by any manufacturer; brand names describe the equipment we service.
Do you serve Brandon, Harrisburg, Tea, and other nearby towns?+
Yes. In addition to Sioux Falls, we serve homeowners in Brandon, Harrisburg, Tea, Hartford, Dell Rapids, Baltic, Crooks, Lennox, Canton, and Worthing.
What should I check before calling for furnace repair?+
Thermostat mode and setpoint, thermostat batteries, the furnace service switch, the breaker, the air filter, and whether the blower door panel is fully closed. These five checks resolve a meaningful share of no-heat calls.
Why is my thermostat on but there is no heat?+
The furnace may have locked out on a safety switch, lost low-voltage power through a blown control board fuse, or failed to prove flame. If a single breaker reset and a clean filter do not restore heat, the system needs diagnostics.
How long does a typical repair visit take?+
Most residential repair visits run 60 to 120 minutes including diagnostics and a common part replacement. Special-order parts can extend that, and we tell you up front when that is likely.
What if my furnace keeps turning on and off?+
That is short cycling, usually caused by restricted airflow, a dirty flame sensor, thermostat placement, or a partially blocked vent. It wears out components quickly and should be diagnosed rather than ignored.
