Every time your thermostat calls for heat, the furnace runs a fixed checklist. The inducer motor starts and proves draft by closing a pressure switch, the hot surface igniter heats up, the gas valve opens, the burners light, and the flame sensor confirms there is fire. Only after all of that does the blower begin sending warm air into the house. Finding the step that fails is most of the job. Around Henderson, NV, the usual failure points are a flame sensor fouled with oxide, an igniter cracked by years of heating and cooling, a pressure switch that stays open because of a weak inducer or a clogged condensate trap on a high-efficiency unit, and control boards with burned relays. Each one halts the startup, and from the hallway they all look alike.
Our experienced technicians diagnose a furnace the way it operates, in order, measuring each stage as it happens. That means igniter resistance, microamp flame signal, pressure switch operation under actual inducer draft, gas valve voltage, and blower and capacitor condition. The safety checks come standard on a gas appliance: heat exchanger inspection, leak testing on the gas connections, and flue draft verification, since a hazard is not visible at the thermostat. We finish by checking temperature rise against the data plate, making sure the burner and blower work together the way the manufacturer designed them to.
We work on gas, propane, and electric models from every major brand, both conventional 80 percent units and condensing high-efficiency models with their traps, drains, and dual pressure switches. The truck stock covers the parts that actually fail: igniters, flame sensors, pressure switches, capacitors, inducer assemblies, and blower motors, so most repairs finish in one trip.

How Much Does Furnace Repair Cost in Henderson?
Most furnace repairs in Henderson cost between $150 and $600. The price depends on which part failed and how old the furnace is. Every furnace repair starts with a real diagnosis and a clear price.
| 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 motorBurners run but little or no air comes out of the vents | $400–$1,500 | No airflow, or the blower runs nonstop |
| Control boardFurnace won't respond to the thermostat | $300–$700 | Erratic behavior, error codes, or no response at all |
| 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
- Whether a cracked heat exchanger is found, which usually means replacement rather than repair
- Timing, such as a no-heat call on a cold night versus a scheduled repair
- How easy the furnace is to reach
When a repair gets expensive on an aging furnace, you'll see both options before deciding. Call (725) 567-4132 to get your price.
Warning Signs for Furnace Repair
The sooner you notice these red flags, the easier and cheaper the problem is to resolve. Keep an eye out for the following clues that it's time to bring in an expert:
- Squealing or grinding from the blower compartment
- The furnace clicks and glows but the burners never light
- Loud booms at startup caused by delayed ignition
- Water, rust stains, or black soot around the flue or cabinet
- A fan that keeps running while the registers blow cool air
- A pilot or burner flame that is lazy yellow instead of crisp blue
- Repeated shutdowns just seconds after the burners light
- Short cycling every few minutes without reaching the setpoint
Early Action Saves Money
A failing capacitor, clogged condensate drain, or dirty flame sensor rarely fixes itself and usually gets more expensive to address the longer it runs. Call Henderson HVAC at (725) 567-4132 at the first sign of trouble.

Why Professional Furnace Repair Matters
A furnace combines gas, flame, high voltage, and a flue in one cabinet, and the failure that matters most is the one you cannot see from outside: a compromised heat exchanger passing combustion gases into the air your blower pushes through the house. Delayed ignition that booms at light-off stresses that exchanger further every morning it goes unfixed. Meanwhile the diagnostic traps stack up: a furnace that trips its high limit may have a bad switch, or it may be protecting itself from a clogged filter or a dying blower, and replacing the switch in the second case just removes a safety while leaving the fault.
Our techs look at every symptom in the context of the whole furnace. We measure flame signal instead of assuming it, which keeps us from replacing a healthy sensor while a cracked igniter or weak gas valve slips past. Draft is confirmed at the pressure switch and at the flue. Temperature rise is checked against the data plate, so airflow issues are caught before they cut years off the heat exchanger. The gas side is leak-tested with instruments, never with a quick sniff. What you get is a furnace proven safe over a full cycle, plus an honest opinion if the unit is getting close to the point where replacing it beats repairing it again.
How Our Furnace Repair Works
We work through a clear, repeatable process so nothing gets overlooked on your property. Here's a look at each step our Henderson HVAC team takes:
Sequence Diagnosis
We run the furnace 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
The heat exchanger is inspected, gas connections are leak-tested, and flue draft verified on every visit. A furnace repair that is not proven safe is not finished.
Same-Visit Repair
We fix the part that actually failed, and since igniters, flame sensors, pressure switches, capacitors, and motors are on the truck, most furnaces are heating again the same visit.
Complete Verification
We run complete cycles, measure temperature rise against the data plate, confirm clean ignition without booming, and verify every limit and safety control before we leave.
Not Sure What You Need?
We provide honest advice and upfront pricing on all furnace repair work.

Taking preventive measures can help you avoid costly heating and cooling problems down the road. Here are our expert recommendations:
- Store laundry supplies, especially chlorine products, well away from the furnace closet
- If you have a high-efficiency furnace, check that the condensate drain is flowing freely
- Notice how the furnace sounds at startup, because a quiet light-off is healthy and a boom is not
- Change the filter monthly during heating season; it is the cheapest furnace part you will ever buy
- Avoid packing the utility room, because burners need open space for combustion air
- Test your CO detectors monthly and make sure each floor has one
- Schedule service each fall to catch worn igniters and dirty sensors before cold weather arrives
DIY vs. Professional Furnace Repair
Some simple checks are suitable for DIY, but most heating and cooling repairs benefit from professional tools, training, and experience. Here's a comparison:
| Factor | DIY Attempt | Professional Service |
|---|---|---|
| Exchanger Cracks | No way to see a crack from outside | Inspected on every repair visit |
| Ignition Problems | Guesswork based on blink codes | Each ignition component tested |
| Gas Safety | Connections judged by smell | Instrument leak test on each visit |
| High-Limit Trips | A safety device jumpered out | The airflow fault behind the trip found |
| Airflow Match | Fan speed never checked | Blower tuned to the rated rise |
| Verification | Declared fixed after one flame | Clean, safe operation verified over full cycles |
