Key Features & Benefits

✅ Complete All-in-One System – Includes indoor unit, outdoor condenser, lineset, cable, and remote. No compatibility concerns or missing parts.

✅ QuickConnect® Pre-Charged Line Set – The 25-ft line set comes filled with R-454B refrigerant and uses quick-connect fittings. No vacuum pump or refrigerant gauges required, making installation truly DIY-friendly.

✅ DIYPRO® Cable Eliminates Conduit – This durable, all-in-one cable combines power and communication wiring. It resists weather, UV rays, and pests—so you can skip the metal conduit and simplify your wiring installation.

✅ Smart Control Your Way – Operate the system with the included wireless remote, the SmartHVAC app (iOS/Android), or voice commands via Amazon Alexa or Google Assistant.

✅ Follow Me Function – The remote acts as a personal thermostat. When enabled, the air handler adjusts airflow based on the remote’s location for personalized comfort throughout your space.

✅ Dry Mode – Acts as a quiet dehumidifier, removing excess moisture to improve indoor air quality and comfort on humid days.

✅ Gold Fin® Condenser – Built with corrosion-resistant fins, ideal for coastal environments and areas with high humidity or harsh weather conditions.

✅ Energy Efficient Operation – Designed for optimal performance with modern R-454B refrigerant, helping reduce energy costs while maintaining powerful climate control.

✅ Industry-Leading Warranty – Backed by a limited lifetime warranty on the condenser coil, 7-year compressor warranty, and 5-year parts warranty.

✅ Certified Safety & Reliability – Intertek listed (5031495) for verified performance and safety standards.
