"Hickory, Kentucky-headquartered MRCOOL has launched an all-in-one heat pump
that plugs into a standard 115-volt outlet and doesn’t have a bulky outdoor
condenser.
The new MRCOOL Monoblock MTHP heats and cools smaller spaces such as garages,
home offices, accessory dwelling units, sunrooms, and tiny homes. It’s designed
for homeowners who want zoned heating and cooling but don’t have the space or
permission to install a conventional mini-split.
What makes the Monoblock unique is that it contains the entire refrigeration
system inside a single wall-mounted unit. A standard mini-split has an indoor
air handler connected to an outdoor condenser via refrigerant lines. The
Monoblock puts those components together indoors, so there are no refrigerant
lines to connect and no equipment pad needed outside.
It does still need access to an exterior wall. Installation requires cutting
two openings through the wall for outside air intake and exhaust, plus a
smaller hole for condensate drainage. So “plug-and-play” doesn’t mean placing
it on the floor and plugging it in.
The unit also weighs around 93 pounds, making installation more likely a
two-person job."
