About This Item

• 12,000 BTU for Up to 550 sq ft: Sized perfectly for master bedrooms, home offices, sunrooms, garages, and studio apartments. Variable-speed compressor adjusts output from minimum to maximum capacity based on actual demand.
• 19 SEER Energy Efficiency: Energy Star certified 19 SEER rating saves 30-50% on heating and cooling costs versus older equipment. Monthly utility bill savings often offset the product cost within 3-5 years.
• Heating Down to 5°F: Cold-climate optimized heat pump maintains heating capacity at outdoor temperatures as low as 5°F, making it suitable for most US climates without requiring auxiliary electric heat backup.
• WiFi Smart Control: Built-in WiFi connects to the Senville app on iOS and Android for remote temperature control, scheduling, and energy monitoring from anywhere in the world.
• Pre-Charged R-410A – DIY Ready: Pre-charged refrigerant line sets (up to 25 feet) are included, eliminating the need for refrigerant handling certification for the initial installation. A licensed HVAC technician still needs to handle line set cutting and final connections.
• Ultra-Quiet Operation: Indoor unit operates as quietly as 26dB(A), ensuring comfortable noise levels in bedrooms and home offices. The outdoor unit runs at 48dB, quieter than a normal conversation at 3 feet.
• Self-Cleaning Evaporator: Automatic self-cleaning mode reduces allergen buildup and maintains optimal heat exchange efficiency by running a periodic drying cycle that inhibits mold growth in the evaporator coil.
