What Is Included in a Typical HVAC Maintenance Checklist?

A typical HVAC maintenance checklist from Shamrock Heating & Cooling covers full-system inspection, cleaning, adjustments, and performance testing for AC, furnaces, heat pumps, and mini-splits. Technicians start with airflow, refrigerant, electrical safety, and thermostat accuracy to boost efficiency and spot issues early. We adapt each tune-up to Arizona desert conditions for homes around Chandler. Plan members get two seasonal visits, priority scheduling, and repair discounts.

Typical checklist specifics:

• Clean evaporator/condenser coils, condenser cabinet, and drain pan.
• Check refrigerant level and lines; adjust charge if needed.
• Inspect/tighten electrical parts; test capacitors, blower motor, and wiring.
• Calibrate thermostat; test airflow/temps; clear condensate drain; service filter.

If you notice uneven cooling, rising bills, or frequent cycling, schedule a tune-up before peak heat. <br/> Updated: 2026-04-02 <br/> Need help in Chandler, AZ? Call (833) 696-0987 or book online.
