24/7 emergency furnace repair
Home Comfort Alliance answers its phones 24/7 and sends NATE-certified technicians for emergency furnace repair, including nights and weekends, across the Seattle-Tacoma area and the wider Puget Sound region. Call (425) 645-0404. Same-day and after-hours service covers every city we serve, for gas and electric furnaces of all major brands.
Smell gas or hear a CO alarm? Leave first. Get everyone out, leave the door open, and call 911 or your gas utility from outside: PSE 1-888-225-5773 or Cascade Natural Gas 888-522-1130. Don't flip switches, use a landline or start a car in an attached garage. Go back in only when the utility or fire department says it is safe.
Is it a furnace emergency?
A furnace problem is an emergency when it is a safety risk or when the home will get dangerously cold before a regular appointment. Use this to decide what to do now.
| What's happening | What to do now |
|---|---|
| Rotten egg (gas) smell | Leave the home, then call 911 or your gas utility from outside. Call us after the utility clears the home. |
| Carbon monoxide alarm, or headache, dizziness or nausea in more than one person | Get everyone outside into fresh air and call 911. Have the furnace checked before using it again. |
| Burning or electrical smell, smoke or sparks | Turn the furnace off at its switch or breaker and call us 24/7. If there is smoke or flame, leave and call 911. |
| No heat with temperatures near or below freezing | Call us 24/7, especially with infants, older adults or anyone medically vulnerable at home. |
| No heat in mild weather | Do the quick checks below, keep warm, and book the next available visit to avoid the after-hours fee. |
| Water pooling around a high-efficiency furnace | Turn the furnace off and call us; a blocked condensate drain can shut it down or damage the floor. |
More on this: emergency no-heat situations.
Quick checks before an emergency call
If nothing on the list above applies, these checks take a few minutes and can save an after-hours fee:
- Thermostat on HEAT, set above room temperature, with fresh batteries.
- Furnace breaker on, and the switch on or near the furnace turned on.
- Filter not clogged; a blocked filter makes the furnace overheat and shut off.
- Furnace front panel fully closed so its safety switch is engaged.
- Outdoor vent pipes on high-efficiency furnaces clear of snow and debris.
Don't relight pilots, open panels or keep resetting the furnace. Repeated lockouts are a safety signal.
Staying safe and warm while you wait
Keep everyone in one room with the door closed, use layers and blankets, and close curtains at night. A portable electric space heater is fine if it sits on the floor, away from bedding, curtains and furniture. Never heat the home with a gas oven, outdoor grill or generator: PSE warns these can cause carbon monoxide poisoning. In a hard freeze, open sink cabinets on outside walls and let a faucet drip to protect pipes (frozen pipe tips).

Emergency furnace repair FAQ
What is considered a furnace emergency?
A furnace emergency is any of these: you smell gas, a carbon monoxide alarm sounds, the furnace smells of burning or shows sparks or smoke, or you have no heat in freezing weather, especially with babies, older adults or someone medically vulnerable at home. A gas smell or CO alarm means leave first and call 911 or the gas utility from outside.
Who do I call if my furnace stops working at night?
If you smell gas or a CO alarm sounds, call 911 or your gas utility from outside. For no heat without those signs, call a 24/7 HVAC company. Home Comfort Alliance answers its phones around the clock at (425) 645-0404 and provides after-hours service across its Puget Sound service area.
How much does emergency furnace repair cost?
Home Comfort Alliance charges a $330 after-hours fee for emergency HVAC calls, alongside the $119 dispatch fee and the diagnostic fee ($72 standard or $130 deeper), then the repair itself. Typical Seattle furnace repairs run $139 to $544 (Angi, August 2026). You approve the repair price before work begins.
Is emergency HVAC more expensive?
Yes. After-hours and weekend calls cost more than a weekday appointment. Angi reports emergency HVAC pros charge about $150 to $215 per hour on average, up to twice a standard call. If the house is safe and warm enough to wait, a next-day visit avoids the after-hours fee.
What should I do while waiting for furnace repair?
Close curtains and doors to unused rooms, gather everyone in one room, and use blankets and warm layers. A portable electric heater on the floor, away from bedding and curtains, is fine. Never heat the home with a gas oven, grill or generator; PSE warns these can cause carbon monoxide poisoning.
Can I reset my furnace myself?
You can check the thermostat, the breaker, the furnace switch and the filter, and make sure the furnace door is closed. Don't keep pressing reset or relighting anything. Repeated lockouts usually mean a safety control is doing its job, and a technician needs to find out why.
Will my pipes freeze if the furnace stops?
They can in a long cold snap, especially pipes on outside walls and in crawl spaces. Keep cabinet doors under sinks open so warm room air reaches the pipes, and let a faucet drip on the coldest nights. See our guide to preventing frozen pipes during a furnace breakdown.
