Maintenance Guide

Seasonal HVAC Maintenance Schedule

Stay ahead of breakdowns with a simple, year-round maintenance rhythm designed for desert climates.

1

Spring Check-Up

Schedule A/C tune-up before the heat hits. Replace filters, clean coils, and test refrigerant levels.

2

Summer Monitoring

Keep filters clean monthly. Watch for unusual sounds, weak airflow, or rising bills — call us if anything seems off.

3

Fall Preparation

Heating system inspection before winter. Test furnace, check heat exchanger, and verify safety controls.

4

Winter Safety

Replace filters monthly during heavy use. Schedule a mid-season check if heating performance drops.
