What Is Included in a Typical AC Tune Up Service?

A typical AC tune-up service includes thorough cleaning, detailed inspection, and performance testing to improve efficiency, reliability, and safety. Most issues we catch are airflow restrictions or refrigerant-related imbalances that make systems work harder than they should. Our technicians adjust settings, verify controls, and document findings so you know what’s good, what to watch, and what’s optional. We also tailor maintenance to Central Illinois seasons to help prevent mid-summer failures.

What our technicians typically do:

• Clean or replace air filters for proper airflow
• Clean indoor evaporator coils and clear debris around the outdoor unit
• Check refrigerant level and scan for leaks; top off if needed
• Inspect and tighten electrical connections; calibrate the thermostat
• Flush the condensate drain line to prevent moisture issues
• Lubricate moving parts and verify blower performance
• Test safety controls and, for heat pumps, reversing valve operation

Change your filter regularly between visits to keep airflow strong. <br/> Updated: 2026-03-12 <br/> Need help in Danvers, IL? Call (309) 317-4215 or book online. "The service was professional, thorough, and completely hassle-free." — Steve W.
