MRCOOL 9,000 BTU Wall Mount Air Handler – DIY-09-HP-WMAH-230D25-O

The 5th Generation MRCOOL® DIY® 9k BTU Ductless Heat Pump Single Zone Mini-Split Air Handler is a compact and efficient solution for heating and cooling spaces up to 400 sq. ft. This unit combines energy efficiency with user-friendly features and do-it-yourself installation.
No specialized tools or professional HVAC experience are needed—just follow the included instructions for a quick and cost-effective setup. The included DIYPRO® cable replaces the need for traditional electrical conduit, streamlining installation while adding durability and protection from outdoor elements and wildlife.
This system offers multiple ways to manage your comfort. You can use the wireless remote, the SmartHVAC app (compatible with iOS and Android), or hands-free voice control with Amazon Alexa and Google Assistant. From scheduling to energy monitoring, complete control is always within reach.
The air handler also includes performance-enhancing features like Follow Me® mode, which senses the temperature at the remote’s location and adjusts airflow accordingly for more accurate comfort. Dry Mode helps reduce humidity, improving air quality and overall comfort. The Gold Fin® condenser coating ensures long-lasting resistance to corrosion, especially useful in coastal or humid environments.
Backed by a 7-year compressor warranty and 5-year parts warranty, along with eligibility for the MRCOOL® Care Program, this unit offers reliable, long-term value. With advanced features and simple installation, the MRCOOL® DIY® 9k Mini-Split is a smart, hassle-free solution for year-round comfort.

Professional Installation Required

Certified HVAC technician installation ensures optimal performance, safety compliance, and full warranty protection.

Important: Check state and local codes and ordinances before purchasing. Product availability and compliance requirements may vary by region.

Where the DIY-09-HP-WMAH-230D25-O fits

This is the indoor unit by itself — a wall-mount head. It pairs with a matching MRCOOL outdoor condenser. It is rated at 9,000 BTU. The DIY line ships with pre-charged Quick Connect line sets — no vacuum pump, no refrigerant handling, no EPA 608 certification. Installing it yourself still keeps the 7-year compressor and 5-year parts coverage.
