What Is Included in a Typical AC Tune Up Service?

A typical AC tune-up service includes a full system inspection, targeted component cleaning, and completion of a detailed maintenance checklist to confirm safe, efficient cooling. Most visits focus on catching wear early, removing buildup that increases strain, and verifying controls so the system starts, cools, and drains as designed. Our technicians complete these checks each spring throughout the Champaign–Urbana area and note what was tested, adjusted, or should be monitored. Technician insight: small airflow or condensate corrections during a tune-up often avert the mid-summer no-cool calls we see most. Members of our Comfort Family receive scheduled spring AC maintenance as part of their plan.

If you notice unusual noises, weak airflow, or water by the air handler before your visit, turn the unit off to prevent damage and schedule service.
