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.
