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 Everett, WA, the failures cluster at predictable points: an oxide-coated flame sensor, 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.
Rather than guess, Everett HVAC tests the sequence stage by stage. We read igniter resistance, measure flame signal in microamps, check that the pressure switch responds to real inducer draft, confirm voltage at the gas valve, and test the blower and its capacitor. Because this is a fuel-burning appliance, the safety basics come with every visit: the heat exchanger gets inspected, gas connections get leak-tested, and draft gets verified. You cannot tell a furnace problem from a furnace hazard by looking at the thermostat. Before we leave, temperature rise is measured against the data plate so the fire and the airflow are balanced as the manufacturer intended.
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 Everett, call (425) 969-3348 and help will be headed your way today.

How Much Does Furnace Repair Cost in Everett?
Most furnace repairs in Everett cost between $150 and $600. Ignition and sensor problems are usually the least expensive, while blower motors, control boards, and heat exchangers cost more. Everett 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 | Furnace lights, then shuts off within seconds |
| 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 motorLoud humming or grinding at startup, then lockout | $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 boardErratic behavior, error codes, or no response at all | $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 |
These are common price ranges, not quotes. We confirm the exact price after diagnosing your system.
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
- How easy the furnace is to reach
When a repair gets expensive on an aging furnace, you'll see both options before deciding. Call (425) 969-3348 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:
- Flames that start, last a few seconds, and go out again and again
- The igniter glows and clicks, yet no flame ever appears
- Frequent on-off cycling that never reaches the thermostat setting
- Soot, rust, or moisture near the furnace cabinet or vent pipe
- Grinding or high-pitched squeals from the blower
- Yellow, wavering burner flames where they should be sharp blue
- Loud booms at startup caused by delayed ignition
- The blower runs constantly but the air never warms
Early Action Saves Money
Most HVAC failures start small, a weak capacitor, a squealing blower, a system that runs a little longer each week. If you notice any of these signs, contact Everett HVAC at (425) 969-3348 for a prompt inspection.

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.
Our experienced technicians 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 shorten the life of the heat exchanger. The gas side is leak-tested with instruments, never with a quick sniff. The result 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 Everett HVAC team takes:
Startup Sequence Testing
We watch the furnace's startup sequence and measure at every stage: inducer draft, pressure switch, igniter resistance, flame signal, and gas valve operation, to find exactly where it breaks.
Safety Inspection
On every visit, we inspect the heat exchanger, leak-test the gas connections, and confirm the flue is drafting. No furnace repair is complete until the unit is proven safe.
Targeted Repair
Igniters, flame sensors, pressure switches, capacitors, and motors ride on the truck, so most furnaces are lit and heating again before we pack up.
Final Cycle Testing
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 little routine maintenance goes a long way toward avoiding a mid-season breakdown. Start with these practical measures our team relies on:
- Keep storage, lint, and especially chlorine-based products away from the furnace closet
- Avoid packing the utility room, because burners need open space for combustion air
- Pay attention when the burners light, since a boom instead of a soft whoosh calls for service
- Put in a fresh filter monthly through the heating season, the cheapest protection your furnace can get
- Book a fall tune-up so weak igniters and fouled sensors are caught before the first freeze
- On high-efficiency models, keep the condensate trap and drain line clear and draining
- Test your CO detectors monthly and make sure each floor has one
Comparing DIY and Professional Furnace Repair
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. Here's a comparison:
| Factor | DIY Attempt | Professional Service |
|---|---|---|
| Exchanger Cracks | Cracks invisible from the outside | Examined as standard on each call |
| Ignition Problems | New igniter installed on a hunch | Igniter, sensor, and valve each metered |
| Gas Connections | Small leaks missed entirely | Every fitting checked with a detector |
| High-Limit Trips | Limit replaced, cause left behind | Root cause of overheating corrected |
| Blower Setup | Airflow assumed, not measured | Rise measured and blower adjusted |
| Verification | It lit once, call it fixed | Clean, safe operation verified over full cycles |
