Frequently Asked Questions
Seasonal Maintenance
We recommend three annual service visits to keep your system running efficiently and maintain your warranty:
- Winterization (mid-September – end of October) — required at the end of every season to prevent freeze damage and maintain your system warranty.
- Spring start-up — recommended each spring to tune the system and optimize performance before the season begins.
- Service calls — available as needed for repairs, new yard projects, or updates.
