Targeted comfort you can install yourself. The MRCOOL® DIY® Easy Pro® 9,000 BTU mini-split heat pump delivers efficient heating and cooling for bedrooms, home offices, studios, guest rooms, and other spaces up to 400 sq. ft.

Its included 11.5 ft. pre-charged Quick Connect® line set uses R-454B refrigerant and eliminates the need for vacuum pumps, manifold gauges, or refrigerant charging. With up to 20.2 SEER2 efficiency, quiet operation, and standard 115V power, it is a practical choice for dependable single-room comfort.

Energy Savings: Delivers up to 20.2 SEER2 and 9.2 HSPF2-4 efficiency. DC inverter technology adjusts compressor output to match actual demand, helping maintain steady temperatures while reducing unnecessary energy use.
Standard 115V Power: Operates on a standard 115V electrical supply, making it a convenient option for smaller residential spaces without requiring a 230V system.
Comfort in Any Climate: Designed to operate in outdoor temperatures ranging from -13°F to 122°F for reliable year-round heating and cooling.
Whisper-Quiet Operation: Runs as low as 18 dB(A) in Sleep mode, making it suitable for bedrooms and offices. Five fan speeds allow precise airflow control, while the outdoor unit operates at approximately 54 dB(A).
Easy Maintenance: Washable, reusable filters reduce replacement costs, while the Gold Fin® corrosion-resistant coating helps protect the outdoor condenser from humidity and environmental wear.
Worry-Free Warranty: Backed by a 5-year compressor warranty and a 3-year parts warranty, with ETL certification for compliance with applicable North American safety standards.

MRCOOL DIY Select 24,000 BTU 16.5 SEER2 Ductless Mini Split System - R454B - 230V

Tom J.

Arrived on time and well packed.

I purchased the MRCOOL DIY Select 24,000 BTU system for my large living area, and it has been working great. It cools the room quickly, maintains a comfortable temperature, and runs much quieter than I expected.

Directions

Fairly easy to install some directions said to use 3 1/2” hole but on template it was 2 1/2” which is what I used. Some of the other directions not to clear, still not sure where the little black filter goes?

Great system, but I wish the Wi-Fi app was a little more polished. Otherwise, no complaints.

Nice little unit. It’s not as powerful as the larger ones of course, but for a small room, it does the job well.
