Signs an Auburn furnace needs repair
From older homes near downtown to newer houses in Lakeland Hills, these are the symptoms that bring us out most often:
- The furnace runs but the house never warms up.
- Nothing happens when the thermostat calls for heat.
- The fan blows but the air is not warm.
- Error codes or a blinking light behind the furnace door.
- Loud banging at startup, squealing from the blower, or rattling in the cabinet.
- The burners light and go out, over and over.
- A smell of burning dust that does not fade after the first run of the season.
Check these first
- Thermostat on HEAT, set above room temperature, with good batteries.
- The furnace's service switch and breaker turned on.
- A clean filter; a clogged one can shut a furnace down on its safety switch.
- The furnace door closed tight, so its safety switch lets it run.
- On high-efficiency furnaces, the white PVC drain and the small pressure-switch tube free of water or debris.
If the heat is still out, write down any blinking code and call. Our guide on why a furnace blows cold air covers the common causes.

Repair or replace an Auburn furnace?
For a furnace under about 15 years old with one failed part, repair is usually the right call. Multiply the age by the repair price; if it comes to more than $5,000, ask for a replacement price too. A cracked heat exchanger or repeated breakdowns are reasons to replace sooner.

Auburn spans King and Pierce counties
We repair furnaces on both the King County and Pierce County sides of Auburn, including Lakeland Hills at the south end of the city. The City of Auburn's comprehensive plan names Puget Sound Energy as the electric and natural gas utility for the city (Auburn private utilities element), and a small area near Auburn Adventist Academy gets gas from Enumclaw Natural Gas. A part-only repair needs no permit. Replacing a furnace inside city limits needs a mechanical permit from the City of Auburn Permit Center (253-931-3090, option 2; building services), and new wiring is permitted through Washington L&I. We pull the required permits for every installation.
A recent Auburn furnace repair: a clogged pressure switch port
In October an Auburn homeowner's furnace, only three or four years old, was running without delivering heat. Our technician found three fault codes stored on the board and traced them to a clogged pressure switch port, the same problem from an earlier visit. He cleared it, showed the homeowner how to clean the port to prevent a repeat, and booked a spring check-up, when surge protection will also be looked at.
From our October 2026 service records; customer details are kept private.
