Every time your thermostat calls for heat, the furnace works through 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 Spokane, WA, 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, 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.
Conventional or condensing, gas, propane, or electric, we work on 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 stocked on every truck: igniters, flame sensors, pressure switches, capacitors, inducer assemblies, and blower motors. That is why most repairs are finished in a single trip. If your furnace is down anywhere in Spokane, call (425) 969-3327 and help will be headed your way today.

How Much Does Furnace Repair Cost in Spokane?
For most Spokane homes, a furnace repair runs $150 to $600. The price depends on which part failed and how old the furnace is. Spokane 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 replacementFurnace lights, then shuts off within seconds | $80–$250 | Burners light but cut out almost immediately |
| Hot surface igniter replacementFurnace clicks and tries to start but never lights | $150–$400 | No ignition; one of the most common winter failures |
| Draft inducer motorStartup fan fails, furnace won't fire | $400–$1,000 | Loud humming or grinding at startup, then lockout |
| Blower motorNo airflow, or the blower runs nonstop | $400–$1,500 | No airflow, or the blower runs nonstop |
| 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.
What Affects 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
- Same-day or after-hours service versus a planned visit
- Access to the furnace in attics, closets, or crawlspaces
For older furnaces facing a big repair, we'll show you what replacement would cost too, so you can compare. Call (425) 969-3327 to get your price.
Signs You Need Furnace Repair in Spokane
Catching these issues early helps you avoid costly problems and protect your property. These are the signals our technicians see most often when a problem is underway:
- The blower runs constantly but the air never warms
- Frequent on-off cycling that never reaches the thermostat setting
- Clicking and a glowing igniter with no burner flame
- Water, rust stains, or black soot around the flue or cabinet
- Repeated shutdowns just seconds after the burners light
- Loud booms at startup caused by delayed ignition
- Grinding or high-pitched squeals from the blower
- A flame that burns soft and yellow rather than steady blue
Don't Wait for a Total Failure
Most HVAC failures start small, a weak capacitor, a squealing blower, a system that runs a little longer each week. Call Spokane HVAC at (425) 969-3327 at the first sign of trouble.

The Benefits of Professional 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 Spokane 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 catch airflow problems early, and test the gas side with a leak detector, 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:
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.
Safety Verification
On every visit, we inspect the heat exchanger, leak-test the gas connections, and confirm the flue is drafting. A repair is not complete until the unit is proven safe.
Targeted 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.
Complete Verification
Before we head out, 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.

A few simple habits now, like regular filter changes and seasonal tune-ups, can add years to your system's life. Here are our expert recommendations:
- Keep storage, lint, and especially chlorine-based products away from the furnace closet
- Listen at light-off; clean ignition is quiet, and booming means the burners need service
- Avoid packing the utility room, because burners need open space for combustion air
- If you have a high-efficiency furnace, check that the condensate drain is flowing freely
- Change the filter monthly during heating season; it is the cheapest furnace part you will ever buy
- Test your CO detectors monthly and make sure each floor has one
- Have the furnace checked every autumn, while a weak igniter or fouled sensor is still an easy fix
Should You DIY or Call a Pro?
While some minor tasks like changing filters or checking a thermostat can be handled by homeowners, most HVAC work involves refrigerant, gas combustion, and high-voltage electricity, jobs that call for professional expertise. Consider the following comparison:
| Factor | DIY Attempt | Professional Service |
|---|---|---|
| Heat Exchanger | Cracks invisible from the outside | Examined as standard on each call |
| Ignition Problems | New igniter installed on a hunch | Every stage measured before replacing parts |
| Gas Connections | Small leaks missed entirely | Instrument leak test on each visit |
| Limit Trips | Limit replaced, cause left behind | Root cause of overheating corrected |
| Blower Setup | Airflow assumed, not measured | Temperature rise set to the data plate |
| Final Check | Declared fixed after one flame | Complete cycles tested before we leave |
