Smell gas? Lynnwood gas service is PSE. Leave the house, then call PSE at 1-888-225-5773 or 911 from outside (PSE leak steps).
Check these five things first
- Thermostat on HEAT, set above room temperature, with fresh batteries.
- Furnace switch and breaker on. Electric furnaces often have two breakers.
- Filter clean. Ceiling and hallway return filters are easy to forget.
- Furnace door closed tight, so the safety switch lets it run.
- Condensate line on a high-efficiency gas furnace clear and draining.
Signs your furnace needs a repair
- Cold air from the vents during a heating call.
- The furnace starts its cycle, then shuts down before the burners light.
- Short cycling or constant running.
- Some rooms never warm up.
- New noises: squeals, rattles or a boom at ignition.
- A burning, electrical or rotten-egg smell.
- Higher PSE or Snohomish PUD bills with no change in use.

Gas or electric furnace?
Lynnwood homes get electricity from Snohomish PUD and natural gas from PSE, so you will find both kinds of furnace here. A gas furnace has an ignition sequence, a draft fan, a gas valve and a flame sensor, and most repairs happen somewhere in that chain. An electric furnace heats with resistance elements switched on in stages, so repairs tend to be elements, sequencers, relays or the blower. Electric furnaces cost more to run, which is why a jump in your PUD bill can be the first sign that a stage has failed and the furnace is running longer to keep up.
How a repair visit works
- Book by phone or online. Same-day service when possible.
- A NATE-certified technician from our Everett team arrives with a stocked truck.
- We read fault codes and watch a full heating cycle.
- We test safety switches, gas pressure or electric heating stages, and venting, and check for carbon monoxide on gas calls.
- You get the repair price in writing and decide. Our trucks are fully stocked, so most repairs can be handled on the spot.
- If a part has to be ordered, you know before the technician leaves, and we come back to install it.

Repair or replace?
A single failed part on a furnace in good condition is usually worth repairing. An older furnace with repeat repairs, a cracked heat exchanger or an electric furnace driving up your PUD bill is the time to compare. We give you the repair price first.
There are no rebates for repairs. If you replace an electric furnace with a ducted heat pump, Snohomish PUD offers $1,800 or $2,500 as an instant discount on the invoice through a registered contractor, and Home Comfort Alliance is one (Snohomish PUD heating rebates). If you heat with PSE gas, PSE pays $1,500 for adding a qualifying ducted heat pump to your furnace (PSE hybrid heat pump rebate).
Replacement estimates are free, and our instant HVAC quote gives a range in about 30 seconds. Most furnace installations take between 4 and 10 hours. What you get with a replacement: a 3-year Comfort Shield labor warranty on new installations, kept active with yearly maintenance. First-year maintenance is included. See furnace replacement in Lynnwood.
Permits and utilities in Lynnwood
Replacing a minor part that does not change the equipment's approval needs no permit (Lynnwood exempt work list). Replacing a furnace needs a City of Lynnwood mechanical permit (Lynnwood mechanical permit checklist), and the City issues its own electrical permits. Some Lynnwood mailing addresses sit outside city limits in unincorporated Snohomish County, where the county issues mechanical permits and Washington L&I issues electrical permits. We check the address and pull the required permits for every installation.
A recent Lynnwood furnace repair: a gas valve that would not open
In October a Lynnwood homeowner in 98036 called because the gas furnace was blowing cold air. Our technician found a very dirty filter and replaced it, then started the furnace by hand and watched the sequence. It reached the gas valve and stopped: the valve was getting its control voltage but not opening.
He checked the gas meter to make sure the supply was on and not locked, then recommended a new gas valve, which our supplier had in stock. On the return visit he installed the valve, checked every joint with an electronic gas detector, watched the burners light, set the gas pressure and ran the furnace through a full cycle from the thermostat.

Lynnwood furnace repair FAQ
How much does furnace repair cost in Lynnwood?
A repair visit has a $119 dispatch (trip) fee, and diagnosis is $72 for a standard diagnostic or $130 for a deeper one. After-hours visits for qualifying emergencies carry a $330 after-hours fee. You get the repair price in writing before any work begins. For context, Angi lists Seattle-area furnace repairs at $139 to $544 (Aug 2026); that is not our price.
Why is my furnace blowing cold air?
Common causes are a dirty flame sensor, a failed ignitor or gas valve, a clogged filter that trips the limit switch, a blocked condensate drain, or the thermostat fan set to ON. Check the filter and thermostat, then book a diagnostic.
Why does my furnace keep turning on and off?
Short cycling usually comes from a dirty filter, a dirty flame sensor, a furnace that overheats or a thermostat problem. It strains parts, so have it checked.
Do you repair electric furnaces?
Yes. We repair gas and electric furnaces. Many Lynnwood homes heat with electricity from Snohomish PUD, and electric furnace repairs usually involve heating elements, sequencers, relays or the blower.
What should I do if I smell gas?
Walk out without using switches or phones inside, and call PSE at 1-888-225-5773 or 911 from the street. When PSE gives the all-clear, we can repair the furnace.
Can you come today or after hours?
Same-day service when possible. Our phones are answered and bookings are accepted 24/7. Heating and cooling technicians work during business hours and are available after hours for qualifying emergencies ($330 after-hours fee), such as no heat in cold weather.
Do I need a permit to repair my furnace in Lynnwood?
Replacing a minor part needs no permit. Replacing a furnace needs a City of Lynnwood mechanical permit, and the City issues its own electrical permits. Addresses outside city limits go through Snohomish County. We pull the required permits for every installation.
Is my address inside Lynnwood city limits?
Not always. Some Lynnwood mailing addresses are in unincorporated Snohomish County. The City of Lynnwood has a map to check, and we confirm before any permit work.
Should I repair or replace my furnace?
It depends on age, repair cost and safety. We give you the repair price first. Replacement estimates are free, our instant quote gives a range in about 30 seconds, and most furnace installations take between 4 and 10 hours.
Are there rebates in Lynnwood?
Not for repairs. If you replace an electric furnace with a ducted heat pump, Snohomish PUD offers $1,800 or $2,500 as an instant discount through a registered contractor such as Home Comfort Alliance. If you heat with PSE gas, PSE offers $1,500 for adding a qualifying ducted heat pump to your furnace.

Almost certainly. Our technicians work on every major furnace brand, and we are a Lennox Premier Dealer and Carrier Factory Authorized Dealer.
