Furnace repair in Kirkland, explained in 30 seconds
Green House Plumbing and Heating repairs and maintains gas and electric furnaces for Kirkland homes, from Kingsgate and Juanita to Houghton and Bridle Trails. We are based at 12040 98th Ave NE in Kirkland (98034), work Monday to Saturday from 7 am to 9 pm, and offer same-day appointments when available.
Most furnace failures come from one worn part: a hot surface igniter, a dirty flame sensor, an inducer motor, a pressure switch, a limit switch or a blower motor. We test the startup sequence step by step, find the failed part, give you an upfront price and fix it, usually on the first visit.
A yearly tune-up in early fall is the best way to avoid a no-heat call on the first cold night.
Furnace will not turn on? Try this first
These checks solve many no-heat calls. If they do not, call us.
- If you smell gas, do not fix anything. Leave the house, do not use switches or phones inside, and call 911 or PSE from outside.
- Check the thermostat. Set to Heat, above room temperature, with fresh batteries.
- Check the furnace switch and breaker. The switch looks like a light switch near the furnace. Make sure the front panel is closed tightly, since a door switch stops the furnace if it is loose.
- Replace the filter. A clogged filter makes the furnace overheat and shut down on its limit switch.
- Count the blinks. Many furnaces have a status light that blinks a code. Note the pattern and tell us when you call.

Repair your furnace or replace it?
We price both, explain the trade-offs and let you decide.
Repair usually makes sense when
- An igniter, sensor, switch or motor failed
- The furnace is under about 15 years old
- It has been reliable until now
- The repair is a small share of a new furnace cost
Replacement usually makes sense when
- The furnace is 15 to 20 years old or more
- The heat exchanger is cracked
- Repairs keep coming back each winter
- You want to add cooling with a heat pump
| Part | What it does | Sign it is failing |
|---|---|---|
| Hot surface igniter | Lights the burners | Clicks, no flame |
| Flame sensor | Confirms the flame is lit | Lights then shuts off |
| Inducer motor and pressure switch | Vents combustion gases safely | Hums, no ignition, error code |
| Limit switch | Shuts down if the furnace overheats | Short cycling, cold air |
| Blower motor | Moves warm air through ducts | Weak airflow, squealing |

What Kirkland homeowners should know about furnaces
Kirkland winters are usually mild and wet, with occasional cold snaps and windstorms that knock out power.
Fall tune-ups beat the rush
The first cold week in October or November brings a wave of no-heat calls. A tune-up in September catches weak igniters and dirty sensors before then.
Windstorms and outages
A gas furnace needs power to run. After an outage, check the breaker and furnace switch, then reset the thermostat. If it shows an error, call us.
Dusty filters in older homes
Older homes in Norkirk, Market and Houghton often have ducts that collect dust and remodel debris. Change filters every one to three months in winter.
Water from high-efficiency furnaces
Many newer Kirkland homes have high-efficiency furnaces that drain water. A clogged condensate line is a common winter call and an easy fix.

Why does my furnace turn on and then shut off?
The most common cause is a dirty flame sensor. Overheating from a clogged filter, a faulty limit switch or a poorly placed thermostat can also cause short cycling.
Why is my furnace blowing cold air?
The furnace may have locked out after failed ignition, overheated on its limit switch, or have a gas supply problem. Check the filter and the thermostat fan setting, which should be on Auto, not On.
How often should a furnace be serviced?
Once a year, ideally in early fall. Change the filter every one to three months during the heating season.
What is included in a furnace tune-up?
We clean the burners and flame sensor, check the igniter, gas pressure, airflow, blower, electrical connections, safety switches and venting, and check for carbon monoxide.
