Common Furnace Problems We Fix in Mukilteo

Here's what's usually behind the problems we see most, and what a fix looks like.

Blowing cold air

Often a dirty flame sensor, failed igniter, or clogged filter tripping a safety. Usually fixed the same day.

No heat or won't turn on

Thermostat, blown fuse, bad igniter, or a control board fault. We carry the common parts on the truck.

Turns on and off

Short cycling usually points to overheating, a dirty flame sensor, or a thermostat problem.

Banging, squealing, rattling

Loose panels, a worn blower motor, or delayed ignition. Worth a look before it gets worse.

Burning or musty smell

Dust burning off on the first cold day is normal. A smell that lingers is not: shut it off and call.

Won't restart after an outage

Windstorms off the Sound knock power out, and some furnaces lock out afterward. We reset it and check why.

Water around the furnace

High-efficiency furnaces make water. A cracked trap or clogged drain line puts it on your floor.

Heating bills creeping up

Usually an airflow problem or a furnace losing efficiency. A tune-up often brings bills back down.

Quick checks before you call

Five things that take two minutes and sometimes save a service call.

  • Thermostat set to Heat, above room temperature, with fresh batteries
  • Air filter not clogged
  • Furnace power switch is on (it looks like a light switch near the unit)
  • Breaker isn't tripped
  • Front panel fully seated (a safety switch shuts the furnace off if it isn't)
  • Still nothing? Call us. Don't keep resetting it; repeated resets can hide a real problem.

How to keep your furnace out of trouble

A well-maintained furnace means better comfort, lower energy bills, and fewer breakdowns. Here’s how to keep yours running like new.

Replace Air Filters

Swap your air filter every 1–3 months to keep airflow strong and reduce strain on your system

Keep Vents Clear

Make sure all vents and returns are free from furniture, rugs, or debris to ensure even heating throughout your home

Listen For Noises

Listen for noises- banging, grinding, or squealing sounds. That’s your furnace telling you something’s wrong; don’t ignore it.

Monitor Utility Bills

Monitor Energy Bills - Rising utility costs may be a sign your furnace is losing efficiency. A tune-up can help bring them back down.

Annual Tune-Ups

Schedule professional furnace maintenance each fall to keep things safe, efficient, and reliable through the cold season

Frequently Asked Questions

Most furnace calls are handled the same day. We drive in from Lake Stevens and take after-hours calls too.

Yes. We take calls 24/7. If you have no heat on a cold night, call (425) 225-4756 and a real person will answer.

Our diagnostic visit is $159. If we can fix the problem on the same visit, we waive it. If a part has to be ordered, such as a manufacturer warranty part, the fee applies.

The most common causes are a dirty flame sensor, a failed igniter, or a clogged filter tripping a safety switch. Check your filter and thermostat first. If that doesn’t fix it, call us.

Sometimes. If it’s a single part and the heat exchanger is sound, a repair can buy several more years. If it’s had repeat repairs or has a cracked heat exchanger, we’ll show you why replacement makes more sense.

Many original Harbour Pointe systems are 25-plus years old and reaching the point where parts wear out in clusters. We’ll tell you honestly whether a repair buys you years or just months.

Yes, especially within a few blocks of the water in Old Town or along Chennault Beach. Salt speeds up corrosion on outdoor heat pump coils and electrical contacts. We check for corrosion on every Mukilteo diagnostic.

Yes. We serve all of Mukilteo and keep common parts stocked in the van, so most furnace repairs are handled same-day in one trip.

Yes. We’re one of the few companies in the area that services gas fireplaces and inserts, so we can look at both on the same visit.

Most repairs don’t need one. A full furnace replacement needs a mechanical permit through the City of Mukilteo, and we pull it for you.
