How furnace maintenance works
What a furnace maintenance job looks like in Gresham.
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.
