MRCOOL ductless mini splits deliver professional-grade heating and cooling without traditional ductwork installation. These versatile heat pump systems range from compact 9,000 BTU units for single rooms to powerful 36,000 BTU configurations for large commercial spaces. You'll find DIY-friendly models with pre-charged linesets and professional-grade systems that handle whole-building climate control across residential and commercial applications where conventional HVAC falls short.
When you need reliable climate control without the expense and disruption of installing ductwork, MRCOOL mini-split heat pumps deliver the performance professionals demand, with the installation flexibility homeowners appreciate. These ductless systems provide year-round heating and cooling using advanced heat pump technology that reverses refrigerant flow, warming spaces in the winter and cooling them in the summer.
The brand's product lineup includes compact Mr Cool 1-ton mini-split units suitable for bedrooms and offices, mid-range 18K BTU models for larger rooms, and high-capacity 36K BTU systems designed for expansive commercial environments. For preassembled outdoor options, explore our MRCOOL Advantage units.
Entry-level systems handle spaces up to 500 square feet and operate quietly, making them perfect for bedrooms, home offices, and small commercial areas. The MRCOOL 9K and 12K BTU models operate on standard 115V electrical service, eliminating the need for costly electrical upgrades in most residential applications.
The MRCOOL DIY 24K hits the sweet spot for garage workshops, master bedrooms, and open-concept living areas spanning 750-1,000 square feet. These systems balance substantial heating and cooling output with manageable power consumption, making them practical where traditional HVAC proves impractical or cost-prohibitive.
Large commercial offices, industrial workshops, and multipurpose facilities that require significant thermal management benefit from 30K- and 36K-BTU configurations. These powerful units maintain comfortable temperatures across expansive square footage while operating more efficiently than multiple smaller systems.
If you're comparing ductless options by tonnage rating, our Heat Pumps category provides additional context to match system capacity to your specific application.
MRCOOL multi-zone systems connect multiple indoor air handlers to a single outdoor condenser unit, creating independent climate zones throughout your building without ductwork installation. Dual-zone configurations serve two separate areas, while 3-zone and larger systems provide customized temperature control across entire homes or commercial facilities.
The DIY 5th Gen multi-zone platform simplifies installation while delivering professional-grade performance. Each indoor unit operates independently. You can cool your bedroom to 68°F while keeping your living room at 72°F … all managed from individual wireless controllers or smartphone applications.
Standard two-car garages require 18K-24K BTU systems to provide adequate heating and cooling, even in extreme temperatures.
Wall-mounted 9K-12K BTU units deliver whisper-quiet performance essential for restful sleep environments. Individual zone control lets each bedroom occupant set preferred temperatures without affecting other areas, while low-decibel operation ensures overnight heating or cooling won't disrupt sleep cycles.
Professional environments benefit from ceiling cassette configurations that integrate cleanly into drop ceiling systems. Hidden mini-split units distribute conditioned air through four-way vents, creating even temperature distribution while maintaining a professional aesthetic. Multi-zone commercial installations provide department-level climate control without the ongoing energy waste of conditioning vacant areas.
Our HVAC specialists help match the right BTU capacity and configuration to your specific space requirements. Whether you need guidance on multi-zone design, technical specifications, or installation planning, our team provides the expertise necessary for informed decisions about your climate control investment.
A 24K BTU ductless mini-split typically covers 1,000 square feet and provides adequate heating and cooling. Ceiling height, insulation quality, window count, and sun exposure affect actual capacity requirements for your specific application.
Yes, these heat pump units operate as air conditioners in warm months and reverse the refrigerant flow for heating in cold weather. Hyper heat models extend heating performance to extreme cold.
Single-zone systems connect one indoor air handler to one outdoor condenser. Multi-zone setups link multiple indoor units to a single outdoor condenser, enabling independent temperature control across different rooms or zones.
Pre-charged linesets eliminate vacuum pump requirements. You'll need a hammer drill, basic hand tools, and proper electrical connections. Quick-connect fittings simplify refrigerant line attachment without specialized HVAC equipment.
Higher SEER2 ratings reduce operating costs through improved efficiency. Units rated 20-23 SEER2 offer strong energy performance. Consider your climate zone, usage patterns, and local electricity rates when evaluating efficiency tiers.
