Furnace Maintenance · Lake Oswego
Annual furnace tune-up: $140 flat, combustion analysis + 21-point inspection.
Lake Oswego ranges from 1940s lakefront cottages and 1970s First Addition homes to large 1990s–2000s estates on Mountain Park and out by Westlake.
Many homes around the lake were built before 1980 with original undersized ductwork that struggles to feed a modern variable-speed heat pump — duct sealing or upsizing is often the quiet half of the install.
We're 15 minutes from our Oregon City shop, so our trucks roll through Lake Oswego most days of the week.

How furnace maintenance works
What a furnace maintenance job looks like in Lake Oswego.
An annual tune-up is the cheapest insurance you can buy for your heating system. Manufacturer warranties on Trane, American Standard, and most major brands require documented yearly service to stay valid — skip a year, the warranty can void.
Every visit covers six core areas: filter inspection, combustion analysis (CO levels, gas pressure, draft, burner condition), electrical safety check, burner and flame-sensor cleaning, blower and airflow check, and a 21-point system walk-through with a written report.
Standalone tune-up: $140 flat. With our Comfort Care maintenance plan: included annually, plus member-rate pricing on any repair work that comes out of the visit.
