Product details

The MRCOOL® DIY® Select 9K BTU 115V Ductless Heat Pump Single Zone Mini-Split Condenser is engineered for true do-it-yourself installation, requiring no specialized tools, prior HVAC experience, or professional labor. Ideal for spare bedrooms, home offices, and other small spaces, it efficiently heats and cools areas up to 400 square feet.

In conjunction with its DIY®-friendly design, the system also delivers strong performance with a 17.5 SEER2 cooling rating and 8.8 HSPF2-4 heating efficiency, providing dependable, year-round comfort while helping reduce energy costs.

Installation is simplified with an 11.5-foot Quick Connect® line set that arrives factory pre-charged with environmentally friendly R-454B refrigerant, eliminating the need for vacuum pumps or refrigerant handling. Most components are included, making setup faster, cleaner, and more accessible for first-time installers.

Comfort control is easy using the included wireless remote or the MRCOOL® Comfort app, which allows temperature adjustments, scheduling, and energy monitoring from anywhere. Compatibility with Amazon Alexa and Google Assistant adds convenient voice control.

On the inside, features like Sleep Mode, Dry Mode, Auto, and programmable scheduling enhance everyday comfort. Meanwhile, a Gold Fin® condenser coating on the outside increases durability, even in humid or coastal environments.

Offering powerful warranty protection, the MRCOOL® DIY® Select 9K BTU 115V Ductless Heat Pump Single Zone Mini-Split Condenser includes a 2-year compressor warranty and 1-year parts warranty for added peace of mind.

Questions & answers

Before you buy

Everything homeowners ask about installing and sizing a MRCOOL system.

Can I DIY the install?

Yes. MRCOOL DIY systems ship with pre-charged QuickConnect line sets, so there is no refrigerant handling, no vacuum pump and no special tools. The MRCOOL app walks you through each step, and most homeowners finish a single-zone install in an afternoon.

What tools do I need?

A drill with a hole saw, a level, two wrenches and basic hand tools. The line set connects by hand and tightens with wrenches, and the mounting hardware is included.

Is a permit required?

Rules vary by county. Many areas allow a homeowner install with a simple permit, though the dedicated electrical circuit often needs a licensed electrician. Check your local code before you start.

What size do I need?

Match the BTU rating to the room you are conditioning. This listing shows its rated coverage in the specifications, and our system finder can size a room in about a minute.
