Product details

Installing your own HVAC system is easy with the MRCOOL® DIY® Select 24K BTU 230V Ductless Heat Pump Single Zone Mini-Split Condenser, designed specifically for homeowners. Built for true do-it-yourself installation, it requires no specialized tools, HVAC certifications, or prior experience. Ideal for living rooms, open-concept spaces, large basements, and bonus rooms, it delivers reliable heating and cooling for areas up to 1,050 square feet.

The system combines strong performance with energy efficiency, offering a 16.5 SEER2 cooling rating and an 8.3 HSPF2-4 heating rating for consistent, 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 vacuum pumps and refrigerant handling. Most components are included, making setup fast and approachable-even for first-time installers.

Comfort control is simple 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 hands-free convenience.

Features like Sleep Mode, Dry Mode, Auto, and a Gold Fin® condenser coating enhance comfort and durability, even in humid or coastal environments.

For added peace of mind, the MRCOOL® DIY® Select system comes with a 2-year compressor warranty and a 1-year parts warranty. This strong, industry-leading coverage demonstrates the pride and confidence MRCOOL has in the craftsmanship and performance of every unit they produce.

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.
