Maintenance Tips to Avoid Costly Repairs
Prevention saves money. Groff’s recommends:
- Change air filters every 60–90 days (use MERV 8–11 for balance of airflow and filtration)
- Schedule bi-annual tune-ups: once in spring (for AC), once in fall (for heat)
- Keep outdoor units clear of leaves, snow, and debris (minimum 2 ft clearance)
- Flush water heater annually to remove sediment (extends life by 3–5 years)
Ignoring these steps can reduce system efficiency by up to 25%, according to the U.S. Department of Energy.
