Maintenance is boring until your system fails on the hottest or coldest day of the year. This checklist covers what homeowners can do and what a professional tune-up should include.
Monthly / as needed
- Check and replace filters (frequency depends on filter type, pets, and dust)
- Keep supply and return vents clear
- Listen for new noises and note any comfort changes
Spring (cooling season prep)
- Clear debris, leaves, and vegetation from around the outdoor unit
- Gently rinse outdoor coil fins if dusty (power off first; don’t bend fins)
- Test cooling on a mild day before peak heat arrives
- Schedule a professional AC tune-up if you skipped last year
Fall (heating season prep)
- Test heat before the first cold snap
- Replace filter ahead of heavier winter runtime
- Check carbon monoxide detectors (for fuel-burning equipment homes)
- Schedule a heating system inspection/tune-up
What a professional visit should cover
More than a filter glance: performance checks, electrical inspection, airflow notes, safety considerations, and prioritized recommendations. See HVAC maintenance services.
