The included DIYPRO cable protects wiring outdoors, while the durable Gold Fin condenser resists corrosion, making it ideal for coastal conditions. Comfort control is easy with the wireless remote, SmartHVAC app, or hands-free voice commands through Alexa and Google Assistant. Advanced features like Follow Me temperature tracking and Dry Mode dehumidification ensure consistent comfort and healthier indoor air. Backed by a lifetime limited warranty, seven years of compressor coverage, and five years of parts protection, this system provides lasting reliability, energy savings, and year-round comfort you can trust.
