When your furnace quits, we come out, find the real problem, and fix it the same day. No corporate sales run-around.



If your furnace is acting up, there's a good chance we've fixed that exact problem this week. We work on all makes and models, gas and electric, old and new.
Thermostat calls for heat and nothing happens. Often an ignitor, flame sensor, or control board.
The fan runs but the air is cold. Could be ignition, a tripped safety switch, or a clogged filter.
Short cycling usually points to a dirty flame sensor, overheating, or an airflow problem.
Blank screen, no response, or it reads the wrong temperature.
Banging, squealing, rattling. We track it down before a small part takes out a big one.
Usually a motor, capacitor, or relay. Common parts we carry on the truck.
Get everyone out of the house first, then call your gas company or 911 from outside. Once it's safe, call us and we'll find and fix the cause.
Straight answer: it depends on what broke. Cleaning a flame sensor and replacing a blower motor are very different jobs. Here’s how our pricing works so you’re never guessing.
We find the real problem and explain it. This fee goes toward the repair if we can fix it the same day.
You get a flat-rate price up front. You say yes or no. No surprise bill at the end.
Bigger repair? We offer financing through Wisetack.
Common repairs like ignitors, flame sensors, and capacitors usually run $85-$300. After-hours emergency calls are $259.

Most furnaces we see can be repaired. That's always where we start.
Replacement only comes up when it really makes sense, like a cracked heat exchanger (a safety issue), a repair that costs close to what a new furnace would, or an old unit that keeps breaking down. Even then, we lay out both options with real prices and let you decide
Want fewer surprises next winter? A yearly furnace tune-up catches small problems before they turn into a no-heat call.

We show up on time
You get the price first
We fix it & warranty it
We make this process as simple and stress free as possible. You get a 1-year parts and labor warranty to protect you from any defects

Most no-heat calls in Marysville get same-day service. We’re based in Lake Stevens, so drive times are short, and we give you a real arrival window when you call.
It depends on the part that failed. Our diagnostic visit is $$159, and you get a flat-rate price before any work starts. Common repairs like ignitors and flame sensors usually run $85-$300.
Yes. We answer calls 24/7. If your heat goes out at 2 a.m. or on a holiday, call (425) 225-4756.
Check two things first: is the thermostat set to HEAT (and the fan on AUTO, not ON), and is the filter clogged? If both look fine, it’s often an ignition problem, a dirty flame sensor, or a tripped safety switch. Those need a tech.
Usually, yes. Age alone isn’t a reason to replace. If the repair is reasonable and the furnace is safe, we fix it. If it’s not worth it, we’ll show you why and give you prices for both options.
All makes and models, gas and electric, old and new.
Yes. We offer 0% financing through Wisetack for bigger repairs.
A dusty smell the first few times you run the heat in the fall is normal and should fade within a day. A burning plastic or electrical smell is not. Turn the furnace off and call us. If you smell gas, leave the house and call your gas company or 911 first.
