AC Maintenance · Lake Oswego
Annual AC tune-up: $140 flat, refrigerant pressures + 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 ac maintenance works
What a ac maintenance job looks like in Lake Oswego.
Spring tune-ups catch the small problems (weak capacitor, low refrigerant, dirty coil) before the next heat wave makes them an emergency. They also keep your manufacturer warranty valid; most brands require documented annual maintenance.
Every visit covers: filter check, refrigerant pressure verification (suction + head, superheat + subcool), electrical safety check (capacitor microfarads, contactor pull-in, amp draw), coil and condensate cleaning, drain line clear, and a 21-point inspection with a written report.
Single visit is $140. Comfort Care members get spring AC and fall furnace tune-ups bundled into one plan, with member-rate pricing on any repair the tech identifies. Most plans pay for themselves the first season.
