MRCOOL DIY 24K BTU Ductless Mini Split Heat Pump

Comparing the DIY 24K and Easy Pro 24K Lineups

About Each Model

• DIY 24K Complete System ($3,329): MRCOOL's flagship 24K system, Energy Star certified at 22.7 SEER2 with R454B refrigerant. Includes a 25-foot pre-charged QuickConnect line set, SmartHVAC Wi-Fi control, Alexa/Google Assistant compatibility, and the strongest warranty in this lineup at 5 years parts, 7 years compressor.

• DIY 24K Air Handler ($965): The indoor unit only, for pairing with a matching DIY 24K condenser or building a multi-zone configuration. Shares the same Energy Star certification, Wi-Fi connectivity, and 5-year parts/7-year compressor warranty as the complete system.

• DIY 24K Condenser ($2,364): The outdoor unit only, includes its own 25-foot pre-charged line set. Features Auto mode, a Timer function, and Gold Fin corrosion resistance. Must be paired with a compatible DIY air handler to function.

• Easy Pro 24K Complete System ($2,149): MRCOOL's budget-tier 24K system at 18.9 SEER2, with a shorter 16-foot pre-charged line set and Fast Connection fittings. Carries a 1-year parts, 2-year compressor warranty, notably shorter than the DIY series.

• Easy Pro 24K Air Handler ($774): The most affordable single component in this lineup. Includes Active Clean Technology and Low Ambient Cooling down to 5°F, useful for server rooms or year-round cooling applications.

• Easy Pro 24K Condenser ($1,375): The outdoor unit only, rated at 61 dB(A) and including its own 16-foot Fast Connection line set. Must be paired with a matching Easy Pro air handler, this listing is condenser-only.

DIY 24K Ductless Mini Split Heat Pump Systems for Commercial Applications

MRCOOL DIY ductless heat pump technology combines high-capacity climate control with accessible installation methods suited for facility maintenance teams. The 24K BTU output addresses substantial heating and cooling demands while maintaining efficiency that reduces your operational costs. These mini-split air conditioners operate on 230V electrical service to provide both summer cooling and cold-weather heating through a single integrated system. You can also shop MRCOOL Advantage units for pre-assembled outdoor options.

Fourth and Fifth Generation Technology Evolution

The 4th-generation MRCOOL ductless mini-split platform established a foundation for simplified installation through pre-charge refrigerant lines and user-friendly mounting hardware, changing how facilities approach HVAC upgrades.

The 5th generation MRCOOL® DIY® 24K BTU models build on this foundation with refined performance features:

• 22.7 SEER2 rating that improves cooling efficiency compared to earlier iterations

• An extended low-ambient heating range that maintains output during cold weather conditions

• Gold Fin® condenser coatings that resist corrosion in coastal and industrial environments where standard coils fail

• Wireless remote control with temperature display and multi-mode selection for convenient operation

• Flexible line set lengths that accommodate diverse installation scenarios across different building layouts

Commercial Application Scenarios

A 24K DIY mini-split system delivers approximately 24000 BTU, suitable for spaces ranging from 800 to 1,050 square feet. Your applications might include office and administrative spaces where ductwork installation is impractical, equipment and server rooms that require consistent temperature control to protect sensitive electronics, retail customer service areas where comfort affects the customer experience, and workshop facilities that need supplemental climate control for year-round productivity.

For smaller spaces or different capacity requirements, Mr Cool 1-ton mini-split options deliver 12,000 BTU of output, suitable for individual offices or workshops.

Built for Demanding Environments

Mr Cool mini splits are engineered to perform reliably in tough commercial settings. The Gold Fin® condenser protection, for instance, resists corrosion from salt air and industrial chemicals, which are common causes of premature failure in standard aluminum coils. Other features are:

• A heavy-duty compressor is designed to handle extended run times typical of commercial use

• The weather-resistant outdoor cabinet protects the electrical components against moisture, dust, and other environmental contaminants that can compromise long-term reliability.

Energy Efficiency That Pays Off

SEER2 ratings measure cooling efficiency under standardized conditions, making it easier to compare performance across models. With a 22.7 SEER2 rating, 5th-generation Mr. Cool systems deliver a significant efficiency upgrade over older HVAC equipment, reducing operating costs year-round. Heating efficiency, measured by HSPF2, further enhances value by minimizing reliance on electric resistance heat during colder months. In many applications, this high-performance heat pump capability eliminates the need for separate heating and cooling systems.

Get Professional Climate Control With DIY Installation Simplicity

MRCOOL DIY 24000 BTU ductless mini split heat pumps deliver the performance your commercial facility needs with installation methods your maintenance team can handle. The combination of pre-charge refrigerant lines, quick-connect fittings, and comprehensive documentation removes traditional barriers to deploying professional-grade HVAC.

Whether you're upgrading aging equipment, adding climate control to previously unconditioned spaces, or addressing hot spots that your existing systems can't adequately serve, the DIY platform provides a practical solution.
