MRCOOL 5th Gen DIY Mini Split - 42,000 BTU 3 Zone Ductless Air Conditioner and Heat Pump with 50 ft. Install Kit, DIYM348HPW00C74

MRCOOL DIY 48,000 BTU 3-Zone Mini Split System with 50 ft. Install Kit

Transform exceptionally challenging property configurations with the superior power and maximum reach needed for today's most demanding extended layouts. The MRCOOL DIY 48,000 BTU 3-Zone system with maximum 50-foot install kit delivers uncompromising climate control across widely distributed living spaces—perfectly suited for ranch-style estates, converted outbuildings, expansive basement conversions, or complex property arrangements where essential living areas exist at substantial distances from the primary structure. This ultimate solution provides optimal comfort for exceptionally challenging residential layouts requiring maximum distance between widely separated living zones while maintaining powerful performance throughout substantially disconnected environments.

This comprehensive package combines a commercial-grade 48K BTU condenser with two versatile 12K BTU air handlers and one substantial 18K BTU air handler, all connected through maximum-length 50-foot pre-charged line sets. The high-capacity extreme-reach configuration creates perfect comfort zones across multiple widely separated living areas—providing the substantial power and maximum reach needed for complex properties where distant rooms, attached workshops, converted garages or basement apartments demand consistent conditioning despite exceptional separation distances. The maximum 50-foot reach accommodates handlers positioned across substantially separated spaces, while the powerful handler sizes perfectly match the conditioning requirements of today's most demanding detached or semi-detached living environments.

The enhanced configuration delivers exceptional climate control across the most challenging extended-property scenarios while providing efficient installation for complex layouts requiring both superior conditioning capacity and maximum possible reach. The maximum-length 50-foot line sets provide perfect connectivity for handlers positioned in substantially separated environments—ensuring consistent comfort throughout widely distributed living areas regardless of their extreme distance from the central condenser. The powerful handlers deliver perfect cooling and heating to medium attached workshops or home offices (376-500 sq ft) and large converted garage spaces or basement apartments (501-750 sq ft) based on their specific dimensions and substantial separation from the main residence.

You'll immediately appreciate the commercial-grade performance when managing comfort across spaces with exceptional horizontal separation and substantially different environmental characteristics based on their distance from the main structure. The maximum 50-foot reach allows strategic handler placement throughout extensively separated environments, while the substantial handler capacities ensure each zone receives powerful climate control matched to its specific dimensions and separated position. The impressive 20.5 SEER2 efficiency rating delivers substantial energy savings despite the extreme-distance operation, while the reliable cold-weather performance maintains consistent heating down to 5°F—ensuring balanced comfort throughout your widely distributed living areas regardless of their substantial separation or independent construction characteristics.

Experience maximum installation flexibility perfectly suited for exceptionally challenging properties with substantially separated living spaces with MRCOOL's innovative pre-charged quick connect technology. The maximum-length 50-foot line sets provide optimized connectivity for complex property configurations—easily adapting to environments where handlers must be positioned in distant converted spaces, separate structures, or substantial property extensions with maximum possible distance from the condenser. The straightforward connection process means you can achieve professional-grade multi-zone comfort without specialized tools or contractor expertise, regardless of your property's exceptionally challenging layout or extreme routing requirements between substantially separated spaces.

The comprehensive installation package includes everything needed for a clean, efficient setup that works with your property's complex extended configuration. The substantial air handlers mount easily on walls throughout widely separated spaces, with capacities perfectly matched to each area's specific conditioning requirements regardless of its substantial distance from the main structure. Your successful DIY installation delivers contractor-quality results across exceptionally challenging extended layouts—providing significant cost savings compared to separate systems for each distant space while creating powerful comfort zones that perfectly match your property's substantial distribution challenges and extreme separation distances.

Take command of your property's widely distributed comfort zones with intelligent controls perfectly suited for managing living areas across substantially separated spaces with distinct environmental characteristics. The SmartHVAC app provides convenient temperature adjustment for each distant zone based on its specific construction characteristics and separation challenges—allowing you to create ideal environments in converted outbuildings with different insulation standards, basement spaces with natural cooling advantages, or garage conversions with substantial solar exposure. Create customized schedules that align with your actual usage patterns for each widely separated space, optimizing energy consumption while maintaining balanced comfort across substantially disconnected living environments with distinctly different construction characteristics and thermal profiles.

The versatile operation modes provide precise control tailored to each separated space's specific environmental challenges. COOL mode delivers perfectly balanced cooling across distant environments despite substantially different construction standards or solar exposure, while HEAT mode provides proportional warmth for areas with different heating requirements due to their separated position and independent construction characteristics. AUTO mode maintains consistent temperatures throughout widely separated living zones despite substantial differences in their natural thermal performance, and DRY mode effectively manages humidity during damp weather across different structures that may experience varying moisture levels based on their construction standards or ground contact.

Experience perfectly balanced multi-zone comfort optimized for exceptionally complex properties with challenging separation between essential living areas. The comprehensive 7-year compressor warranty and 5-year parts warranty ensures lasting peace of mind, while the maximum 50-foot reach provides ultimate connectivity for challenging extended-property configurations. Transform your widely distributed living environments with powerful, adaptable comfort that's perfectly matched to your property's exceptional separation challenges—delivering personalized temperature control across substantially disconnected spaces without requiring separate systems for each distant area or compromising comfort in any part of your complex extended property arrangement
