- Energy Efficiency at Its Best: With a 20.5 SEER rating and the ability to heat reliably in temperatures as low as 5°F, this system keeps energy costs low year-round.
- Smart Control: The SmartHVAC app lets you or your clients adjust settings from anywhere using a smartphone, adding convenience and modern appeal to your installations.
- Built to Last: Featuring corrosion-resistant Gold Fin® coating and backed by a limited lifetime compressor warranty (upon registration), plus 7 years on the compressor and 5 years on parts, you can trust in the system’s durability and reliability.
