No heat in Kent? Check these first
A few quick checks solve some no-heat calls before anyone drives out:
- Set the thermostat to HEAT, raise it a few degrees and replace its batteries if the screen is blank.
- Pull the air filter. A filter packed with dust can trip the furnace's limit switch and shut the burners off.
- Check the furnace power switch (it looks like a light switch on or near the unit) and the breaker in your panel.
- Make sure the blower door on the front of the furnace is closed tight. The furnace will not run with it loose.
- Look at the outdoor vent pipes on high-efficiency furnaces. Leaves or ice in them can stop the furnace.
Still no heat? Call (425) 645-0404 and tell us what the furnace is doing, any error light it shows and how old it is.
Signs your furnace needs repair
- Air from the vents is cool or barely warm while the thermostat calls for heat.
- The burners light, run a few minutes and shut off, again and again.
- The furnace clicks or hums but never lights.
- A status light on the control board blinks an error code.
- New noises: banging when it lights, squealing from the blower, or rattling inside the cabinet.
- A burning or electrical smell that lasts more than the first few minutes of the season.
- Rooms on East Hill or in the valley that never warm up, or a gas bill that jumped without a reason.
Any of these is worth a diagnostic. A burning or electrical smell is a reason to turn the furnace off and call right away.

Permits and utilities in Kent
Puget Sound Energy supplies both natural gas and electricity in Kent, so PSE is the number to call for a gas leak and the utility behind any rebate. PSE lists no rebate for furnace repairs or tune-ups (checked October 2026).
- Repairs: part-only repairs need no permit.
- Replacing a furnace inside city limits: a mechanical permit from the City of Kent Permit Center, 400 W. Gowe, (253) 856-5300. New or moved equipment and gas piping go on the permit.
- Kent mailing addresses outside city limits: King County Permitting issues the mechanical permit when a furnace is installed, moved or replaced.
- Electrical work: permits come from Washington L&I.
We pull the required permits for every installation, so you do not have to visit the Permit Center yourself.
Repair or replace a Kent furnace?
Most furnace problems are worth repairing. Replacement starts to make sense when the furnace is near the end of its life, the repair is large, or the same fault keeps coming back.
One rule of thumb is the $5,000 rule: multiply the furnace's age by the repair price, and if the result is over $5,000, price a replacement before you decide. It is a guide, not a verdict. A furnace around 30 years old is usually past its expected life, and parts get harder to find, so replacement is often the better spend.
We always price the repair first. If you want to compare, our instant quote gives a replacement range in about 30 seconds, the in-home estimate is free, and our furnace replacement in Kent page covers sizing, permits and financing.
A recent Kent furnace repair: a blank thermostat and a worn wire
In October a Kent homeowner's gas furnace stopped heating and the thermostat screen had gone blank. The homeowner suspected the thermostat. Our technician traced the problem outdoors instead: a low-voltage wire at the outdoor unit had rubbed against the copper refrigerant piping until its insulation wore through, and the short kept tripping a fuse in the system.
He rerouted the wire so it no longer touches the piping, sealed the worn section and restarted the system, which was running normally before he left. The thermostat did not need replacing after all.

Who should I call when my furnace stops working in Kent?
Call Home Comfort Alliance at (425) 645-0404. Our phones are answered and bookings are accepted 24/7, and our Sumner team serves all of Kent.
Can you come after hours?
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 or a burning or electrical smell.
Can you fix my furnace on the first visit?
Our trucks are fully stocked, so most repairs can be handled on the spot. If a part has to be ordered, we tell you before we leave.
What should I check before calling?
Check the thermostat mode and batteries, the air filter, the furnace power switch and breaker, and that the blower door is closed. If you smell gas, leave the home and call PSE at 1-888-225-5773 or 911 from outside.
Why is my furnace blowing cold air?
Common causes are a failed ignitor or flame sensor, a clogged filter tripping the limit switch, or a thermostat set to fan "on". A diagnostic finds the real fault.
What is the $5,000 rule for furnaces?
Multiply the furnace's age by the repair cost. If the result is over $5,000, replacement is usually worth pricing. It is a rule of thumb, not a verdict: we give you the repair price and, if you ask, a free replacement estimate.
Is it worth replacing a 30-year-old furnace?
Often yes. A furnace that old is past the usual life and parts get harder to find. We still price the repair first, and our instant quote gives a replacement range in about 30 seconds.
Do I need a permit for a furnace repair in Kent?
Part-only repairs need no permit. Replacing a furnace or adding gas piping needs a City of Kent mechanical permit, or a King County permit outside city limits, and we pull the required permits for every installation.
Are there rebates for furnace repair in Kent?
No. PSE lists no repair, maintenance or gas furnace rebate (checked October 2026). PSE heat pump rebates may apply if you replace your system.
Is Home Comfort Alliance licensed?
Yes. WA Contractor Reg. #HOMECCA785BD and WA Electrical Contractor Lic. #HOMECCA782DC. We are licensed, bonded and insured in Washington.
