When the furnace quits at 20 below, you need someone who answers, arrives, and has the part on the truck. We publish our prices, we show you the failed component, and nobody here earns a commission for selling you a new system.
Takes about 20 seconds. We call you back fast — and if it is urgent, calling us is quicker.
Nine times out of ten your problem is on this list — and several of them are things you can check yourself in two minutes before spending a dollar.
The thermostat calls for heat and the furnace does not respond. No fan, no click, no ignition sequence.
Usually: Tripped breaker, the furnace service switch bumped off, a blown low-voltage fuse on the control board, or a failed transformer.
You hear it light, it runs briefly, then the flame cuts out. Often repeats three times, then locks out entirely.
Usually: A dirty flame sensor. This is the single most common furnace repair in Sioux Falls and it is inexpensive.
The blower runs but the air coming out of the vents is room temperature or colder.
Usually: Thermostat fan set to ON rather than AUTO, a flame sensor fault, or the high-limit switch tripping from restricted airflow.
The furnace runs for a few minutes, shuts down, and restarts. Never completes a full heating cycle.
Usually: A plugged filter, restricted return air, an oversized furnace, or a failing limit switch. Left alone, this destroys heat exchangers.
Works fine most of the time, quits during a cold snap or a windstorm, sometimes resets itself.
Usually: Blocked or drifted sidewall vent on a high-efficiency unit, a wind-affected pressure switch, or on propane, a supply pressure problem at the tank.
A distinct boom or bang a few seconds after the furnace tries to light.
Usually: Delayed ignition — gas accumulating before it lights. This one needs attention promptly; it is hard on the heat exchanger and it is a genuine safety concern.
A high-pitched squeal, a metallic grinding, or a rumble that was not there last winter.
Usually: Worn blower motor bearings, a failing inducer motor, or a loose blower wheel. Grinding usually means the bearings are already gone.
A hot, dusty smell on the first fire of the season, or an acrid electrical smell any time.
Usually: Dust burn-off on the first run of the year is normal and fades in an hour. An electrical or plastic smell is not — shut it off and call us.
The burner flame is lazy, yellow or orange rather than a crisp blue.
Usually: Incomplete combustion — dirty burners, inadequate combustion air, or a cracked heat exchanger. This is a carbon monoxide concern. Get it inspected.
Smell gas, or your CO detector is going off? Do not troubleshoot. Get everyone out of the house, call 911 or MidAmerican Energy's emergency line from outside, and then call us at (605) 555-0199.

|---|---|
| Flame sensor clean or replace | $180 – $280 The most common furnace repair we do |
| Hot surface ignitor | $220 – $350 Usually finished in under an hour |
| Pressure switch | $225 – $400 Frequently a symptom of a blocked vent — we check that first |
| Capacitor | $180 – $300 Inexpensive part, quick job |
| Inducer motor | $450 – $850 Common on 2005–2014 high-efficiency units |
| Blower motor | $450 – $800 ECM motors run at the higher end |
| Gas valve | $450 – $750 Varies significantly by brand and model |
| Control board | $450 – $900 We verify it is actually the board before replacing it |
| Heat exchanger | Usually not worth it On most units this is the point to price a replacement — we will show you why |
| Fall tune-up & safety inspection | $129 Cheapest insurance against a January emergency call |
Prices are typical ranges for residential systems in the Sioux Falls metro and include parts and labor. After-hours, weekend and holiday rates differ and are always quoted on the phone before we dispatch. Your written estimate is the binding number.

The second-opinion promise. If another company has quoted you a furnace replacement, we will come out and give you an independent diagnosis. We do not sell or install equipment, so we earn nothing from a replacement. Sometimes the replacement is the right call — and we will tell you that too.
Because the techs we work with stock for this market: the ignitors, flame sensors, pressure switches, inducer motors, capacitors and control boards that actually fail on Sioux Falls equipment — not a generic parts list. In January, a second trip means another night in a cold house, and that is the whole reason it matters.
Call (605) 555-0199 →A real person answers, 24 hours a day. Tell us what the system is doing and we will give you an honest arrival window for your Sioux Falls address — not a vague all-day promise.
Our technician tests the system, finds the actual fault, and hands you a flat price in writing before touching a tool. Approve it, decline it, or think about it. Zero pressure.
Most repairs are finished on the first visit from parts already on the truck. You get a 1-year workmanship warranty from the technician plus full manufacturer coverage on every part installed.
Sioux Falls averages somewhere around 7,500 heating degree days a year, and it is not unusual for us to string together a week where the high never climbs above zero. A furnace that would coast through a Kansas City winter runs long, hard duty cycles here — and long duty cycles are exactly what expose a marginal ignitor, a tired inducer motor or a partially blocked flue.
That is also why the failures cluster. When the temperature drops to -20°F, every furnace in the metro runs closer to its limit at the same moment, and the ones with a weak component give out on the same night. It is why you can call four companies during a January cold snap and get voicemail at three of them.
If none of that brings it back, call us at (605) 555-0199. You will have done the free troubleshooting already, and that gets our technician to the real problem faster.
We are new. You can see that, and pretending otherwise would be the fastest way to lose your trust before we have earned it. So here is what you can actually verify today, before anyone touches your equipment.
What we can show you right now is how well we know Sioux Falls — the equipment in these houses, how it fails here, and what it actually costs to fix. That is on every page of this site. Read it, then judge us on it.
Our diagnostic is $89–$129 and it is credited toward the repair when you approve the work. Beyond that, most Sioux Falls furnace repairs fall into a predictable range: an ignitor or flame sensor is $180–$350, a pressure switch $225–$400, a gas valve $450–$750, an inducer motor $450–$850, a blower motor $450–$800, and a control board $450–$900. You see the flat price in writing before we start, and the invoice matches it.
Most Sioux Falls no-heat calls are handled the same day, and emergency calls are dispatched immediately at any hour. You will get a real arrival window when you call rather than a vague all-day promise. Calls with infants, elderly residents, medical needs or pets in the home go to the front of the board. If the house is already below about 50°F, tell us on the phone — that changes how we triage it.
The three most common causes, in order of how often we find them: the flame sensor is dirty and the furnace is shutting the gas off a few seconds after ignition; the fan setting on the thermostat is on ON instead of AUTO, so the blower runs constantly and pushes room-temperature air; or the furnace is overheating and tripping its high-limit switch because of a plugged filter or restricted return air. The first one is a cheap fix. The third one, left alone, cracks heat exchangers.
It is genuinely dangerous — a cracked heat exchanger can allow combustion gases, including carbon monoxide, into your living space. It is also one of the most abused diagnoses in this industry, because it is expensive and hard for a homeowner to verify. Our policy is simple: if we tell you the heat exchanger is cracked, we show you the camera footage of the crack. If a company condemns your furnace without showing you the actual defect, get a second opinion before you spend anything.
Under 12 years old and the repair is less than a third of a replacement — repair it. Between 12 and 15 years, it depends on which component failed and how well the unit has been maintained. Past 15 years, a major failure like a cracked heat exchanger, a failed gas valve on an already-tired unit, or a blower assembly usually is not worth the money. We give you both numbers and let you decide. Nobody here is paid commission on equipment sales.
Yes — they are the majority of what we service in the newer Sioux Falls, Harrisburg, Tea and Brandon subdivisions. Condensing furnaces bring their own failure modes: sidewall PVC vent blockages from snow and ice, condensate drain freeze-ups, corroded secondary heat exchangers, and pressure switch faults. These are all things a technician needs to have actually seen before, and we see them every winter.
Go outside and look at the two white PVC pipes coming through your wall. In a Sioux Falls winter those get drifted over, iced up, or blocked by a bird or wasp nest, and the furnace's pressure switch shuts it down as a safety measure. Clear a two-foot radius around both pipes. This is the single most common no-heat call we run from December through March, and it frequently costs nothing to fix yourself. If it keeps recurring even with clear pipes, the vent termination may need to be relocated out of the prevailing wind.
The technicians we work with back their repairs with a 1-year workmanship warranty, on top of the full manufacturer warranty on any part installed. Get the warranty terms in writing with your estimate — that is standard, and anyone reluctant to put it on paper is telling you something useful.
All major residential brands: Lennox, Carrier, Trane, Bryant, Goodman, Amana, Rheem, Ruud, York, American Standard, Payne, Heil, Armstrong, Daikin and Coleman. The technicians we dispatch stock the ignitors, flame sensors, pressure switches, capacitors and common control boards that fail most often on these units, so the majority of repairs are finished on the first visit.
Yes. Propane is common on the acreages around Renner, Crooks, Hartford and Valley Springs. LP systems need different orifice sizing and manifold pressure, and a furnace that only faults out on the coldest nights is very often a propane supply problem rather than a furnace problem — we test at the tank as well as at the unit. Mention it is propane when you call so we load the right parts.
Same pricing and same response priority in every town. No trip charge inside roughly 25 miles of downtown.
No sales appointment, no pressure, no waiting on hold. If we cannot help, we will tell you who can.
