A typical HVAC maintenance checklist from Cole Services includes seasonal tune-ups, safety checks, diagnostics with a written report, and airflow assessments. Most tasks aim to keep equipment efficient and safe while preventing breakdowns and uneven temperatures. Technicians serving the Anaheim area follow these steps during scheduled maintenance, and select tune-up promotions on our site may include a no-breakdown guarantee.
Typical items during maintenance visits:
- Air conditioner inspection and tune-up.
- Furnace safety check.
- Indoor Air Analysis with ductwork and blower checks for balanced airflow.
- Install a new 1" filter.
Keep access to your equipment clear and change interim filters as recommended to protect your system between visits.
