What Is Included in a Typical AC Tune Up Service?

A typical AC tune-up from Windy City HVAC Repair includes a full system inspection, cleaning, and performance check to restore safe, efficient operation. Most issues we find trace back to airflow restrictions, low refrigerant charge, or control problems that make the system work harder than it should. We check the AC end to end, address dirt and debris that block heat transfer, verify refrigerant levels are correct, and evaluate the compressor and electrical controls for wear or faults. Our team services systems throughout Chicago’s southwest suburbs, so we understand how local summer heat exposes weak filters and borderline charge around Bolingbrook. A small refrigerant undercharge often shows up as a warm second floor before any safety switch trips. Maintenance plan options add priority scheduling, discounts, and no after-hours fees.

What we typically do during an AC tune-up:

• Inspect the unit and locate any refrigerant leaks, then repair if needed
• Measure refrigerant and recharge to proper levels when required
• Clean or replace filters and clean coils to restore airflow and heat transfer
• Check compressor condition and troubleshoot electrical and control issues
• Verify thermostat and control operation for correct system cycling

If you notice reduced cooling or ice on the refrigerant lines, turn the AC off and schedule service to prevent compressor damage. <br/> Updated: 2026-03-28 <br/> Need help in Bolingbrook, IL? Call (312) 500-4822 or book online.
