MRCOOL 5th Gen DIY Mini Split - 42,000 BTU 3 Zone Ductless Air Conditioner and Heat Pump with 35 ft. Install Kit, DIYM348HPW00C49

MRCOOL DIY 48,000 BTU 3-Zone Mini Split System with 35 ft. Install Kit

Transform complex multi-story environments with the enhanced power and reach needed for today's most demanding multi-level layouts. The MRCOOL DIY 48,000 BTU 3-Zone system with extended 35-foot install kit delivers exceptional climate control across vertically distributed living spaces—perfectly suited for multi-story townhomes, split-level residences, or substantial two-story properties where living areas span multiple floors requiring significant vertical and horizontal conditioning reach. This advanced solution provides optimal comfort for challenging residential layouts requiring exceptional vertical distance between strategically separated living zones while maintaining powerful performance throughout substantial floor plans.

This comprehensive package combines a powerful 48K BTU condenser with two versatile 12K BTU air handlers and one substantial 18K BTU air handler, all connected through extended 35-foot pre-charged line sets. The high-capacity extended-reach configuration creates perfect comfort zones across multiple vertically separated living areas—providing the robust power and exceptional vertical reach needed for multi-level homes where rooms on different floors demand consistent conditioning despite significant vertical separation. The extended 35-foot reach accommodates handlers positioned across different floors, while the substantial handler sizes perfectly match the conditioning requirements of today's most common room configurations on separate levels.

The enhanced configuration delivers exceptional climate control across the most challenging multi-story spaces while providing efficient installation for homes with complex vertical designs requiring both superior conditioning capacity and extended reach. The extended 35-foot line sets provide perfect connectivity for handlers positioned on different floors—ensuring consistent comfort throughout vertically separated living areas regardless of their floor position or substantial distance from the central condenser. The powerful handlers deliver perfect cooling and heating to medium upper-level bedrooms (376-500 sq ft) and large main-floor living areas (501-750 sq ft) based on their specific dimensions and vertical position within the property.

You'll immediately appreciate the professional-grade performance when managing comfort across spaces with substantial vertical separation and different environmental characteristics based on their floor level. The extended 35-foot reach allows strategic handler placement throughout multi-level environments, while the substantial handler capacities ensure each zone receives powerful climate control matched to its specific dimensions and floor position. The impressive 20.5 SEER2 efficiency rating delivers substantial energy savings despite the extended vertical operation, while the reliable cold-weather performance maintains consistent heating down to 5°F—ensuring balanced comfort throughout your multi-story living areas regardless of natural temperature stratification between floors.

Experience vertical installation flexibility perfectly suited for challenging multi-story homes with complex floor plans and significant level changes with MRCOOL's innovative pre-charged quick connect technology. The extended 35-foot line sets provide optimized connectivity for multi-level residential designs—easily adapting to properties where handlers must be positioned on different floors with substantial vertical and horizontal 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 home's challenging vertical layout or inter-floor routing requirements.

The comprehensive installation package includes everything needed for a clean, efficient setup that works with your home's complex multi-level architecture. The substantial air handlers mount easily on walls throughout different floors, with capacities perfectly matched to each level's specific conditioning requirements. Your successful DIY installation delivers contractor-quality results across architecturally challenging multi-story layouts—providing significant cost savings compared to separate systems for each floor while creating powerful comfort zones that perfectly match your home's vertical distribution and inter-level thermal challenges.

Take command of your home's vertically distributed comfort zones with intelligent controls perfectly suited for managing living areas across different floors with distinct thermal characteristics. The SmartHVAC app provides convenient temperature adjustment for each level based on its specific height-related thermal profile—allowing you to create ideal environments in upper floors that naturally retain heat and lower levels that tend to remain cooler due to natural thermal stratification. Create customized schedules that align with your family's actual usage patterns for each floor, optimizing energy consumption while maintaining balanced comfort across vertically separated living spaces with distinctly different natural temperature tendencies.

The versatile operation modes provide precise control tailored to each floor's specific thermal challenges. COOL mode delivers perfectly balanced cooling across different levels despite naturally warmer upper floors, while HEAT mode provides proportional warmth for areas with different heating requirements due to their vertical position and natural thermal characteristics. AUTO mode maintains consistent temperatures throughout vertically separated living zones despite the natural tendency for heat to rise through your home, and DRY mode effectively manages humidity during damp weather across different floors that may experience varying moisture levels based on their vertical position.

Experience perfectly balanced multi-zone comfort optimized for complex multi-level homes with challenging vertical separation between living areas. The comprehensive 7-year compressor and 5-year parts warranty ensures lasting peace of mind, while the extended 35-foot reach provides exceptional connectivity for sophisticated multi-story designs. Transform your multi-level living environment with powerful, adaptable comfort that's perfectly matched to your home's vertical architectural challenges—delivering personalized temperature control across different floors without requiring separate systems for each level or compromising comfort on any floor of your complex multi-story residence.
