Air handler service
The air handler is the indoor unit that moves heated and cooled air through your ducts. We keep it running with:
- Filter cleaning or replacement
- Clearing the condensate drain and pan to prevent leaks and rust
- Checking wiring and the blower motor
- Repair or replacement when it’s 10–15 years old, has poor airflow or mold buildup
Why regular maintenance matters
A yearly tune-up keeps your AC efficient, catches small problems before they become breakdowns and helps the system last longer. The Guardian Maintenance Plan includes a spring AC tune-up and priority service.
