HVAC

Mini split heat pumps and HVAC systems from MRCOOL, the #1 brand in DIY ductless heating and cooling. Mini splits are individual heating and cooling units that mount on a wall, ceiling, or floor and connect to an outdoor compressor. No ductwork needed, making them the best option for additions, garages, basements, and homes without existing ducts.

MRCOOL's DIY line is designed for homeowner installation. The pre-charged refrigerant lines use quick-connect fittings, no HVAC license or vacuum pump required. Shop by zone count, BTU capacity, or series below. Free shipping on every system.
