MRCOOL DIY 9K BTU 5th Gen Ductless Mini Split Condenser - 115V
Installing an HVAC system yourself might seem impossible, but the 5th Generation MRCOOL® DIY® 9k BTU 23.6 SEER Ductless Heat Pump Single Zone Mini-Split Condenser is designed for exactly that. With no special tools or experience required, this system can heat or cool spaces between up to 350 sq. ft. The pre-charged 25-foot QuickConnect® line set makes installation safe, simple, and cost-effective.
Pre-filled with R-454B refrigerant, it eliminates the need for vacuuming. The included DIYPRO® cable replaces the need for electrical conduit, offering added durability against weather, animals, and yardwork tools. You can control the system using the included remote, the SmartHVAC app on Apple or Android devices, or voice commands via Amazon Alexa and Google Assistant. For coastal homes, the Gold Fin Condenser provides superior corrosion resistance, ensuring long-lasting performance. This system offers multiple modes and features to enhance comfort and efficiency. The Timer function helps reduce energy use, while Auto mode maintains your set temperature effortlessly. After a power outage, the system automatically restores previous settings. The anti-mildew function prevents mold by reducing excess condensation in the air handler.
