What Is Included in a Typical AC Tune Up Service?

A typical AC tune-up service from Shamrock Heating & Cooling includes a full-system inspection, cleaning, performance testing, and safety checks to keep your unit efficient and reliable. Most performance loss comes from dirty coils, clogged filters, or small electrical issues that make the system work harder in hot weather. We often catch weak capacitors during spring checks before they fail under summer load. We tailor these visits to Arizona’s desert heat and regularly help homeowners in and around Mesa. Members can opt for two seasonal visits with priority scheduling and repair discounts.

Here’s what technicians typically do during the visit:

• Deep-clean evaporator and condenser coils, cabinet, and drain pan.
• Service airflow and controls: replace/clean filters, calibrate the thermostat, and run performance tests.
• Check the refrigerant system and adjust levels if needed; inspect lines and connections.
• Inspect and tighten electrical components; test capacitors, blower motor and wheel; clear the condensate drain; lubricate moving parts as required.

Schedule your tune-up before peak heat so minor wear doesn’t become a no-cool emergency. <br/> Updated: 2026-04-30 <br/> Need help in Mesa, AZ? Call (833) 696-0987 or book online.
