An AC tune-up includes a full inspection, targeted cleaning, and adjustments to keep the system efficient, reliable, and safe. The most common work is cleaning and testing the parts that affect airflow and refrigerant balance, then verifying electrical and control settings. We follow this same thorough process for homes across the Oregon area. If anything is out of spec, we explain what it means and recommend repair or monitoring. A slightly miscalibrated thermostat can mimic a refrigerant issue until pressures are checked. Membership plans are available to make routine visits easier and more cost‑efficient.
A standard visit typically covers:
- Coil cleaning and condenser rinse, plus airflow checks.
- Refrigerant level and system pressures measurement with a quick leak look‑over.
- Electrical connections, capacitors, and safety controls testing.
- Blower motor, air handler, drain line clearing, filter service, and thermostat calibration.
Schedule service before the first heat wave and keep a clean filter to reduce strain on the system. <br/> Updated: 2026-03-31 <br/> Need help in Oregon, WI? Call (608) 291-6473 or book online. “Cardinal Heating maintenance plan is the way to go! … very professional and knowledgeable.” — Jessica B.
