Why Lake Stevens Homes Need Specific HVAC Attention
Lake Stevens sits at a higher elevation than much of Snohomish County, and the lakeside neighborhoods see more temperature swings — cold, damp winters and warm summers. Many homes here were built in the 1980s and 1990s with builder-grade Carrier or Lennox gas furnaces that are now 25–35 years old and well past their expected lifespan. We also see a lot of newer construction in the Getchell Road and 20th Street SE corridors where heat pumps are the primary heat source. Whether your home has a gas furnace, a heat pump, or a dual-fuel system, we know what's common in this area and carry the parts to fix it.
Recent Furnace & HVAC Repairs in Lake Stevens
These are real jobs we've completed in Lake Stevens. Brand, problem, diagnosis, and what we did to restore heat.
Getchell Road area
Problem
No heat — furnace cycling on and off every few minutes
Diagnosis
Cracked heat exchanger triggering the high-limit safety switch. The furnace was 28 years old.
Outcome
Advised replacement given age and safety risk. Installed a new Rheem 96% AFUE gas furnace. Home had heat the same day.
Lake Stevens waterfront
Problem
Heat pump running constantly but not reaching set temperature in January
Diagnosis
Low refrigerant charge — slow leak at the service valve. Auxiliary electric heat was carrying the full load, driving up the electric bill.
Outcome
Located and repaired the leak, recharged the system with R-410A, verified proper operation. Customer saved an estimated $80–$120/month in electric costs.
20th Street SE corridor
Problem
Furnace igniting but shutting off after 2–3 minutes
Diagnosis
Dirty flame sensor — a common issue on Goodman variable-speed furnaces after 8–10 years. The sensor couldn't confirm a stable flame and the control board shut the unit down as a safety measure.
Outcome
Cleaned and tested the flame sensor. Furnace ran through a full heating cycle without issue. Total repair time: 45 minutes. $69 diagnostic applied to the repair.
What Lake Stevens Customers Say
"Our furnace went out on a cold Tuesday morning. I called Snohomish Furnace and Air and they had a tech at our house by early afternoon. He diagnosed a bad inducer motor, had the part on his truck, and we had heat back before dinner. Honest pricing and no upsell pressure."

"We've used them twice now — once for a furnace tune-up and once when our heat pump stopped heating in February. Both times they were on time, explained everything clearly, and charged exactly what they quoted. We won't call anyone else."
Dave & Shelly T.
Lake Stevens, WA · Heat Pump Repair
"Jeff came out and found the problem with our Lennox furnace in about 20 minutes — a cracked heat exchanger we didn't even know about. He showed us photos and explained the safety risk clearly. We replaced the furnace and the whole process was smooth. Highly recommend."

My furnace is over 20 years old — should I repair or replace it?
It depends on the repair cost and the condition of the heat exchanger. As a general rule, if the repair costs more than half the price of a new system and the furnace is over 18–20 years old, replacement usually makes more financial sense. We'll give you an honest assessment — we don't push replacements when a repair is the right call.
