Is your Woodinville furnace telling you it needs service?
A furnace rarely fails without a warning. Call when you notice any of these:
- The house will not reach the thermostat setting, or one floor stays cold.
- The furnace hums or the draft fan runs, but the burners never light.
- Heat starts, then the furnace shuts down and tries again a few minutes later.
- A blinking status light on the control board.
- Air from the registers feels room temperature during a heating call.
- Higher PSE bills with no change in how you use the house.
- A sharp burning or electrical odor, or a loud bang at startup.
Quick things to try first
- Confirm the thermostat is on HEAT and the setting is above the room temperature; swap weak batteries.
- Look at the breaker and the service switch beside the furnace; both need to be on.
- Pull the filter. If it is matted with dust, a new one may be all the furnace needs.
- Make sure the lower door on the furnace is fully closed; an open door cuts power by design.
- On a high-efficiency furnace, check that the white plastic drain line is not kinked or full of water.
If none of that brings the heat back, note any blinking pattern and call. Our furnace won't turn on guide covers these steps in more detail.
Woodinville furnace repairs we handle
Woodinville has everything from older split-levels with standard gas furnaces to newer homes with variable-speed and communicating systems. We repair them all, on every major brand.
| System | Typical repairs | Good to know |
|---|---|---|
| Standard gas furnace | Ignitor, flame sensor, gas valve, limit switches, control board | We check venting and carbon monoxide on every gas call. |
| High-efficiency (condensing) furnace | Condensate trap and drain, pressure switch, inducer motor | A blocked drain can shut the furnace down with no other fault. |
| Variable-speed or communicating furnace | Blower module, control board, thermostat communication faults | We are a Lennox Premier Dealer and a Carrier Factory Authorized Dealer, so we know these controls well. |
| Electric furnace | Heating elements, sequencers, relays | Often the best candidate for a switch to a heat pump later. |

Should you fix it or replace it?
If the furnace is under about 15 years old and one part has failed, fixing it is usually the better value. If it is older, has needed several repairs, or the technician finds a cracked heat exchanger, get a replacement price before paying for a big repair. Age times repair cost above $5,000 is a common signal to compare.
Woodinville homes on PSE gas can keep the furnace and add a heat pump; PSE pays $1,500 for that hybrid setup, plus up to $2,400 through its income-based Efficiency Boost (pse.com, October 2026).

Your Woodinville repair visit, step by step

- We read the fault code, watch a full heating cycle, and test gas pressure, airflow and every safety switch.

Woodinville utilities, county lines and permits
The City of Woodinville lists Puget Sound Energy as the provider of both natural gas and electricity for its residents. Not every Woodinville address is inside city limits: Cottage Lake and Hollywood Hill are unincorporated King County, and Maltby is unincorporated Snohomish County. We work in all of them.
No permit is needed for a part-only repair. Replacing a furnace, or new gas line work, needs a mechanical permit from the City of Woodinville inside city limits (city permit FAQ), or from King or Snohomish County outside them. Electrical permits come from Washington L&I. We pull the required permits for every installation.
A recent Woodinville no-heat call: a control board fault
In October a Woodinville gas furnace stopped heating. Our technician traced the problem to the control board: on a call for heat, the board was sending about 20 volts to the inducer motor instead of the 120 volts the motor needs, so the furnace could never start its heating cycle. He explained the fault, recommended replacing the board, and planned a recheck of the inducer motor for any damage once the new board was in.
