MRCOOL DIY 5th Generation Mini-Split

The DIY 5th Generation is MRCOOL's flagship homeowner-installable ductless mini-split, and the claim that defines it is specific: it is the only mini-split on the market designed for full homeowner installation, with no HVAC licence, technician or vacuum pump required. The enabling technology is the pre-charged line set, which connects without evacuating the system. That claim is backed rather than asserted. MRCOOL's pre-charged line set valves are tested and certified by Intertek under UL STD 207 and CSA STD C22.2 #140.3 (certification number 5029931), rated to handle 921 PSI and validated for strength and leakage at Intertek's Plano, Texas lab. The design is patent-protected and works with R-454B refrigerant, the lower-GWP replacement now being phased in across the industry. Energy Star certified models are available in the range.

Mitsubishi Electric Hyper-Heat Pump

The Mitsubishi Electric Hyper-Heat Pump system utilizes advanced Inverter technology and patented flash injection compressor design to provide exceptional heating performance even when outdoor temperatures plunge as low as -13°F. It serves as a versatile, energy-efficient solution for year-round climate control in residential and light commercial spaces. Designed for ultimate indoor comfort, this ductless mini-split system eliminates cold spots by continuously modulating compressor speed rather than cycling on and off. Homeowners benefit from precise temperature zoning, whisper-quiet operation, and significantly reduced energy consumption compared to traditional fossil fuel or electric resistance heating systems.

Senville LETO Series Mini Split

The LETO Series is Senville's high-efficiency single-zone ductless mini split, sold across the full residential BTU range from 9,000 up to 48,000 BTU. It both cools and heats, and Senville sizes the range by room area as well as BTU, with published bands from 100 to 500 square feet up to 1,250 to 1,500 square feet, which makes selecting the right unit considerably less error-prone than working from BTU alone. As with all mini splits, dehumidification comes as part of the cooling cycle, so the unit removes excess moisture while it runs. Senville sells the LETO alongside ultra-high-efficiency and hyper efficiency tiers, Alexa-enabled models, ceiling cassettes, concealed duct and floor-mounted formats, and multi-zone configurations up to five zones for whole-home coverage.
