Every system carries 6-year compressor, 3-year parts, and 90-day remote coverage automatically, no registration required. Register within 60 days of installation and the term extends to 10-year compressor and 8-year parts. Full terms are on our warranty page.

How fast does it ship?

Orders are processed and ship within 2 to 3 business days from our California and Texas warehouses. Freight is free and already included in the price, with no separate freight charge at checkout.
