A modern furnace runs a strict startup sequence, and knowing where the sequence breaks is most of the diagnosis. The thermostat calls, the inducer motor spins up to prove draft through a pressure switch, the hot surface igniter glows, the gas valve opens, the burners light, the flame sensor confirms fire, and only then does the blower deliver heat to the house. In Draper, UT, the failures cluster at predictable points: a flame sensor coated in oxide that can no longer prove the flame, a hot surface igniter cracked from years of thermal cycling, a pressure switch that will not close because the inducer is weak or the condensate trap on a high-efficiency model has clogged, or a control board with a burned relay. Each one stops the sequence cold, and each one mimics the others from the hallway.
Draper HVAC repairs furnaces by testing the sequence, not guessing at it. Our experienced technicians watch the startup step by step and measure at each stage: igniter resistance, flame signal in microamps, pressure switch operation against actual inducer draft, gas valve voltage, and blower and capacitor health. Every visit includes the safety fundamentals on a fuel-burning appliance: heat exchanger inspection, leak-testing of gas connections, and flue draft verification, because the difference between a furnace problem and a furnace hazard is not visible from the thermostat. We measure temperature rise against the data plate before we leave so the fire and the airflow are matched the way the manufacturer intended.
Conventional or condensing, gas, propane, or electric, we repair them all, across every major brand, including the traps, drains, and dual pressure switches that come with high-efficiency models. The parts most likely to fail are already stocked on the truck: igniters, flame sensors, pressure switches, capacitors, inducer assemblies, and blower motors. That is why the majority of no-heat calls end the same visit. If your furnace is down anywhere in Draper, call (385) 206-5938 and we will get the burners lit today.

How Much Does Furnace Repair Cost in Draper?
Most furnace repairs in Draper cost between $150 and $600. Cleaning a flame sensor is a small job; replacing a blower motor or control board is a bigger one. Draper HVAC tests the system, finds the actual fault, and quotes the repair before any work begins.
| Repair | Typical cost | What it usually means |
|---|---|---|
| Flame sensor cleaning or replacementBurners light but cut out almost immediately | $80–$250 | Burners light but cut out almost immediately |
| Hot surface igniter replacementFurnace clicks and tries to start but never lights | $150–$400 | Furnace clicks and tries to start but never lights |
| Draft inducer motorStartup fan fails, furnace won't fire | $400–$1,000 | Startup fan fails, furnace won't fire |
| Blower motorNo airflow, or the blower runs nonstop | $400–$1,500 | Burners run but little or no air comes out of the vents |
| Control boardFurnace won't respond to the thermostat | $300–$700 | Furnace won't respond to the thermostat |
| Gas valve replacementIgniter glows but gas never flows to the burners | $250–$700 | Valve fails to open, so the furnace never lights |
Ranges are typical for these repairs; you get an exact quote before any work starts.
Factors That Change the Price
- Furnace age and type, because 90%+ efficiency models have more specialized parts
- A cracked heat exchanger, which is a safety issue and usually points to replacement
- Same-day or after-hours service versus a planned visit
- How easy the furnace is to reach
When a repair gets expensive on an aging furnace, you'll see both options before deciding. Call (385) 206-5938 for a quote.
Signs You Need Furnace Repair in Draper
Recognizing the warning signs early can save you time, money, and prevent significant damage to your property. Watch for these telltale signs that professional help is needed:
- Short cycling every few minutes without reaching the setpoint
- Squealing or grinding from the blower compartment
- A bang or boom when the burners ignite late
- Soot, rust, or moisture near the furnace cabinet or vent pipe
- A flame that burns soft and yellow rather than steady blue
- The igniter glows and clicks, yet no flame ever appears
- The blower runs constantly but the air never warms
- Flames that start, last a few seconds, and go out again and again
Early Action Saves Money
Most HVAC failures start small, a weak capacitor, a squealing blower, a system that runs a little longer each week. At the first hint of a problem, reach out to Draper HVAC at (385) 206-5938 for a fast inspection.

Why Hire a Professional for Furnace Repair?
Gas, open flame, high voltage, and a flue all share one cabinet in a furnace, and the most dangerous failure is the one you cannot see: a damaged heat exchanger that lets combustion gases into the air the blower circulates. Every morning that delayed ignition keeps booming at startup, that exchanger takes more stress. The diagnostic side has its own pitfalls. When a furnace trips its high limit, the switch itself may be bad, or the furnace may be protecting itself from a clogged filter or a failing blower. Replacing the switch when the real issue is airflow removes a safety device and leaves the actual problem in place.
At Draper HVAC, no symptom gets treated in isolation. A meter tells us the flame signal, so we never condemn a good sensor while the real culprit, a cracked igniter or a weak gas valve, keeps causing trouble. We confirm draft at both the pressure switch and the flue, measure temperature rise against the data plate to flag airflow problems early, and leak-test every gas connection with instruments, not a guess. When we are done, the furnace has proven itself safe and correct through a full cycle, and if it is nearing the end of its useful life, you will get an honest assessment.
What to Expect From Our Furnace Repair
We work through a clear, repeatable process so nothing gets overlooked on your property. Here's a look at each step our Draper HVAC team takes:
Step-by-Step Diagnosis
The furnace is run through its startup while we measure inducer draft, pressure switch response, igniter resistance, flame signal, and gas valve operation. The goal is to pinpoint the exact step that fails.
Combustion Safety Check
Safety is part of every repair: heat exchanger inspection, instrument leak testing on the gas side, and flue draft verification, because a furnace that runs is not the same as a furnace that runs safely.
Expert Repair
Most furnace repairs finish in one trip. The common failure parts, from igniters and flame sensors to pressure switches, capacitors, and motors, are stocked on the truck and ready to go.
Final Cycle Testing
Before we leave, the furnace runs full cycles while we check temperature rise against the data plate, listen for clean, quiet ignition, and test each limit and safety control.
How to Prevent Furnace Repair Problems
A little routine maintenance goes a long way toward avoiding a mid-season breakdown. Put these technician-approved steps to work around your property:
- Pay attention when the burners light, since a boom instead of a soft whoosh calls for service
- Put a carbon monoxide detector on every level and test them monthly
- Replace the filter every month while the furnace is working hard, since it costs less than any other part
- Store laundry supplies, especially chlorine products, well away from the furnace closet
- Schedule service each fall to catch worn igniters and dirty sensors before cold weather arrives
- If you have a high-efficiency furnace, check that the condensate drain is flowing freely
- Avoid packing the utility room, because burners need open space for combustion air
Should You DIY or Call a Pro?
Online tutorials may help in a pinch, yet lasting repairs and code-compliant installations usually depend on professional methods and trained technicians. Here's a comparison:
| Factor | DIY Attempt | Professional Service |
|---|---|---|
| Exchanger Cracks | Damage hidden inside the cabinet | Inspected on every repair visit |
| Ignition Faults | Parts swapped against a code list | Igniter, sensor, and valve each metered |
| Gas Connections | A loose union goes unnoticed | Every fitting checked with a detector |
| High-Limit Trips | A safety device jumpered out | Filter, blower, and ducts checked for the cause |
| Blower Setup | Fan speed never checked | Rise measured and blower adjusted |
| Final Check | It lit once, call it fixed | Clean, safe operation verified over full cycles |
