Gas, electric and oil furnaces in Monroe
Monroe homes get electricity from Snohomish PUD and natural gas from PSE, and some older homes in and around town still heat with oil. We repair all three. Gas furnace repairs usually sit in the ignition chain: ignitor, flame sensor, gas valve, pressure switch and draft fan. Electric furnaces fail at the elements, sequencers and relays. Oil furnaces need a yearly cleaning, with a new nozzle and filter, or soot builds up and the burner starts tripping. An oil furnace tune-up is $336, or $288 for Home Comfort Club members.

Repair or replace: the $5,000 rule
A common rule of thumb multiplies the furnace's age by the repair cost. A 15-year-old furnace with a $400 repair scores 6,000, which says it is time to at least price a replacement. A 6-year-old furnace with the same repair scores 2,400, so repairing is the easy call. It is only a guide: safety, comfort and your plans for the house matter too. We always give you the actual 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 through a registered contractor such as Home Comfort Alliance (Snohomish PUD heating rebates). PSE gas customers can get $1,500 for adding a qualifying ducted heat pump to a gas 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 Monroe.

Permits and utilities in Monroe
Replacing minor parts needs no permit. Replacing a furnace in the City of Monroe needs a mechanical permit from the Permit Division (360-863-4501, Monroe permits), plus an electrical permit from Washington L&I if wiring changes; Monroe does not issue its own electrical permits. Homes outside city limits go through Snohomish County Planning and Development Services, which also requires a permit for gas piping. We pull the required permits for every installation.
A recent Monroe furnace repair: a failed ignitor and a decision
In early September a Monroe homeowner in 98272 called with no heat and a hunch that the ignitor had failed. Our technician tested it, and the meter read it as an open circuit. He replaced it with a universal nitride ignitor and the furnace lit and heated again.
Because the furnace was older, he walked the homeowner through the cost of future repairs against the age of the equipment and priced a replacement. The homeowner chose a new 80% gas furnace, and we scheduled the installation for later that month.

Monroe furnace repair FAQ
How much does furnace repair cost in Monroe, WA?
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.
What is the $5,000 rule?
A rule of thumb: multiply the furnace's age by the repair cost. Above about $5,000, replacement is usually worth a look. We give you the actual repair price first so you can decide.
Why is my furnace blowing cold air?
Most often the burners are not lighting (a worn ignitor or a sooty flame sensor), or they light and then shut off because a dirty filter tripped the limit switch. A thermostat fan left on ON also blows room-temperature air between cycles.
Why is my furnace short cycling?
Short cycles usually trace back to airflow (a clogged filter or closed registers), a flame sensor that cannot prove the flame, a pressure switch fault or a thermostat in a bad spot. Each restart wears the ignitor and blower, so get it looked at.
Do you repair oil furnaces in Monroe?
Yes. We service gas, electric and oil furnaces. An oil furnace tune-up is $336, or $288 for Home Comfort Club members.
What should I do if I smell gas?
Get everyone out without flipping switches or lighting anything, then call PSE at 1-888-225-5773 or 911 once you are outside. We repair the furnace after PSE clears the home.
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 Monroe?
Replacing minor parts needs no permit. Replacing a furnace needs a City of Monroe mechanical permit, and electrical permits come from Washington L&I. Outside city limits, Snohomish County issues permits. We pull the required permits for every installation.
Do you serve Sultan and Gold Bar?
