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 Reno, NV, 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.
Our experienced technicians diagnose a furnace the way it operates, in order, with a meter at every step. That means igniter resistance, microamp flame signal, pressure switch operation under actual inducer draft, gas valve voltage, and blower and capacitor condition. Safety checks are never optional on a gas appliance: heat exchanger inspection, leak testing on the gas connections, and flue draft verification, since a hazard rarely shows itself at the thermostat. We finish by checking temperature rise against the data plate, making sure the burner and blower are matched the way the manufacturer designed them to.
We work on natural gas, propane, and electric furnaces 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 Reno?
The typical furnace repair in Reno lands between $150 and $600. Ignition and sensor problems are usually the least expensive, while blower motors, control boards, and heat exchangers cost more. 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 | Furnace lights, then shuts off within seconds |
| Hot surface igniter replacementNo ignition; one of the most common winter failures | $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 boardErratic behavior, error codes, or no response at all | $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
- The age and efficiency of the furnace, since high-efficiency models use 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
- Access to the furnace in attics, closets, or crawlspaces
If your furnace is past 15 to 20 years old or the repair is a major one, we'll give you repair and replacement prices side by side. No heat right now? Call (775) 314-3282.
Warning Signs for Furnace Repair
Recognizing the warning signs early can save you time, money, and prevent significant damage to your property. Here are the most common indicators that it's time to call a professional:
- Squeals, scrapes, or grinding noises behind the blower door
- A furnace that shuts off every few minutes before the house warms up
- A fan that keeps running while the registers blow cool air
- The furnace clicks and glows but the burners never light
- Flames that start, last a few seconds, and go out again and again
- A bang or boom when the burners ignite late
- A flame that burns soft and yellow rather than steady blue
- Soot, rust, or moisture near the furnace cabinet or vent pipe
Early Action Saves Money
What seems like a minor issue today can take out a compressor or heat exchanger tomorrow. If you notice any of these signs, contact Reno HVAC at (775) 314-3282 for a prompt inspection.

Why Hire a Professional for Furnace Repair?
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.
At Reno 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, stays in place. We confirm draft at both the pressure switch and the flue, measure temperature rise against the data plate to catch 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
Our systematic workflow delivers thorough, lasting results on every job. Here's exactly how the furnace repair process unfolds:
Sequence Diagnosis
Instead of guessing, we follow the startup sequence one stage at a time, with readings on the inducer, pressure switch, igniter, flame sensor, and gas valve, until the broken link shows itself.
Safety Inspection
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.
Targeted Repair
We fix the confirmed fault, and since igniters, flame sensors, pressure switches, capacitors, and motors are on the truck, most furnaces are heating again the same visit.
Final Cycle Testing
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.

A few simple habits now, like regular filter changes and seasonal tune-ups, can add years to your system's life. Start with these practical measures our team relies on:
- Clear boxes, lint, and above all chlorine-based cleaners out of the furnace area
- Pay attention when the burners light, since a boom instead of a soft whoosh calls for service
- Have the furnace checked every autumn, while a weak igniter or fouled sensor is still an easy fix
- Put a carbon monoxide detector on every level and test them monthly
- Change the filter monthly during heating season; it is the cheapest furnace part you will ever buy
- On high-efficiency models, keep the condensate trap and drain line clear and draining
- Give the furnace room to breathe, since a crowded utility space starves the burners of air
Comparing DIY and 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 |
|---|---|---|
| Heat Exchanger | Damage hidden inside the cabinet | Checked every time we open the unit |
| Ignition Problems | New igniter installed on a hunch | Each ignition component tested |
| Gas Safety | A loose union goes unnoticed | Instrument leak test on each visit |
| Limit Trips | Limit replaced, cause left behind | Filter, blower, and ducts checked for the cause |
| Blower Setup | Airflow assumed, not measured | Blower tuned to the rated rise |
| Final Check | Declared fixed after one flame | Complete cycles tested before we leave |
