What maintenance should be done on an AC unit yearly?

Yearly AC maintenance should include a full inspection, deep cleaning, and performance testing to keep the system efficient, reliable, and safe. Most issues that drive higher bills and breakdowns come from dirt on coils and a clogged drain line that make the unit work harder.

We routinely perform this maintenance for homes throughout the Garden Ridge area with the same technician care used across our Texas service calls. For a scheduled visit, our Elmerization (Tune-Up) is listed at $129.

What a pro will typically do each year:

• Replace/inspect the air filter and clean indoor evaporator and outdoor condenser coils.
• Clean the blower assembly and verify fan operation.
• Flush and clear the condensate drain line.
• Run performance tests for refrigerant pressures, temperatures, and mechanical operation.

If you’re not trained, leave coil, electrical, and refrigerant checks to a licensed technician. <br/> Updated: 2026-04-03 <br/> Need help in Garden Ridge, TX? Call (210) 489-1389 or book online.
