About MRCOOL
MRCOOL is a brand in the heating, ventilation and air conditioning market, supplying equipment that warms, cools and manages the indoor climate of homes and commercial buildings. Its range covers ductless mini-split systems, heat pumps, central air conditioning units, smart thermostats and cooling products made for recreational vehicles. What the brand is best known for is mini-splits built around do-it-yourself installation.
MRCOOL was started in 2014 and works out of Hickory, Kentucky. Its DIY units arrive with pre-charged line sets and quick-connect fittings, so a homeowner can put a system in place without brazing refrigerant lines or pulling a vacuum, the steps that normally call for a licensed technician.
Alongside the equipment, MRCOOL publishes installation documentation and warranty resources and keeps technical support on hand for residential and commercial climate projects. Its products reach buyers through home improvement retailers, online sellers and a dealer network.
Ductless mini-splits of the kind MRCOOL makes are common in homes without ductwork, in additions and in rooms that a central system struggles to reach, since each indoor head conditions its own space.
