Sound familiar?
The furnace problems we fix every week
No heat at all
A failed igniter, flame sensor, control board or gas-valve issue. Most "dead" furnaces are running again within the hour, we carry the common parts on the truck.
Blowing cold air
Often a dirty flame sensor shutting the burner down for safety, or a thermostat set to "on." Quick to diagnose, usually quick to fix.
Banging, rattling, screeching
A bad blower bearing, a cracked belt, or a delayed gas ignition "boom." Noises never fix themselves, but caught early, they're cheap.
Short cycling
Turning on and off every few minutes overheats and wears parts fast. Causes range from a clogged filter to a failing limit switch, we'll find yours.
Heating bill spiked
A furnace losing efficiency runs longer to hit the same temperature. Often a dirty burner, failing inducer, or duct leak quietly costing you money.
Smells or a yellow flame
A burning or "hot dust" smell early in the season is usually normal; a persistent gas or musty smell, or a yellow burner flame, is not. Shut it down and call.

Don't wait on these
Is it an emergency, or can it wait?
Most furnace problems can wait a day for a normal appointment. A few shouldn't, here's how to tell the difference.
Call right away
- You smell gas (rotten egg). Leave the house and call your gas utility first, then us.
- A carbon-monoxide alarm is going off, get everyone outside and call from there.
- No heat in a cold snap with infants, elderly family or pets in the home.
- A burning, electrical or hot-plastic smell that won't clear, shut it off at the switch.
- A breaker that trips again every time you reset it.
Safe to book normally
- A mild drop in efficiency, the house still warms up, it just takes longer.
- A new rattle or hum that isn't getting worse.
- A faint "hot dust" smell in the first hour of the heating season.
- One room that's always run a little cool.

Repair FAQ
Common furnace repair questions
How much does furnace repair cost in Bellevue?
Most common repairs land between $150 and $600, a flame sensor, igniter or capacitor on the low end, a blower motor or control board higher up. Big-ticket items like a heat exchanger run more. We diagnose first, give a flat-rate price before any work, and waive the diagnostic fee when you approve the repair. See the cost table above for typical ranges.
Why is my furnace running but blowing cold air?
The most common cause is a dirty flame sensor: it can't confirm the flame, so the furnace shuts the gas off for safety and you're left with the blower pushing cool air. A thermostat set to "on" instead of "auto" does the same thing. Both are quick fixes. Our troubleshooting guide covers the checks to try first.
Is it worth repairing an old furnace?
Under about 12 years, almost always yes. Past 15 it depends on the repair, a $250 igniter is worth it at any age, but a $2,000 heat exchanger on an 18-year-old furnace usually isn't. We'll show you the honest math against a replacement and let you decide.
How long does a furnace repair take?
Most repairs are done in a single visit, often within an hour of diagnosis, because we stock the common furnace parts on the truck. A rare or back-ordered part occasionally needs to be ordered, and we'll tell you the timeline the moment we know.
Do you offer same-day or emergency furnace repair?
Yes, we hold same-day slots across Bellevue and the Eastside, and we run an after-hours emergency line for evening, weekend and no-heat situations and gas-safety concerns. Call early in the day for the best shot at a same-day visit.
What's the most common furnace repair?
A dirty or failed flame sensor, by a wide margin, followed closely by the hot-surface igniter. Both are small, inexpensive parts that give out with age and carbon buildup, and both are easy same-visit fixes. They're also exactly what a yearly tune-up catches before they leave you without heat.
Reviews
What Bellevue homeowners say about our repairs
"No heat on a Sunday morning. They walked me through shutting it down safely, came out, and found a cracked igniter. Fixed in under an hour and the price was exactly what they quoted."
"Diagnosed a bad flame sensor that two other companies somehow missed. Clean, fast, and they didn't try to sell me a whole new furnace. I'll be calling them from now on."
"Our furnace was short-cycling for weeks. They found a clogged filter and a failing limit switch, fixed both the same visit, and showed me how to keep it from happening again."
