The MRCOOL Monoblock is a 10,000 BTU through-wall heat pump that heats, cools, dehumidifies and circulates air from one cabinet on an exterior wall, with no outdoor unit. Its DC inverter compressor is rated 10,000 BTU/h cooling at 95°F and 9,000 BTU/h heating at 47°F, at 15 SEER2, on a standard 115V circuit.
It suits a single room, addition or apartment where a mini-split condenser cannot be placed outside, as long as the wall can take two 8" vent holes. Installation is by a licensed technician. That is the MRCOOL Monoblock MTHP Series.
Features
No Outdoor Unit
Compressor, coils and fans share one 39.4" W x 23.1" H x 8.07" D cabinet that vents through the wall behind it.
Four Modes
Cool, heat, fan and dry, with dry mode removing up to 2.5 pints/hr of moisture.
DC Inverter Compressor
Output varies from 3,000 to 12,000 BTU/h, rated 15 SEER2, 9.9 EER2 and 7.5 HSPF2.
Heats Down to 5°F
Heating runs in outdoor temperatures from 5°F to 75°F, with 6,500 BTU/h still available at 17°F.
Quiet Indoors
Rated sound pressure runs from 32 dBA on its lowest setting to 46 dBA at its highest.
Sealed R-32 Circuit
Factory charged with 19.4 oz of R-32, so no refrigerant lines are run or charged on site.
Remote, Display and App
Control it from the LED panel or the included remote, with a 24-hour on/off timer; MRCOOL lists smartphone app control over Wi-Fi as an optional feature.
Water-Full Protection
A water-full alarm with auto-stop shuts the unit down before the internal tray can overflow.

Installation
Professional installation required. This equipment must be installed by a qualified, licensed electrician or contractor, following MRCOOL's installation manual and all local electrical and building codes and permit requirements. MRCOOL's limited warranty applies only to units installed that way, and it does not cover installation labor.
Mounts on a flat, solid exterior wall that can carry 93.5 lbs, ideally no thicker than 9.5". Two 8" ventilation holes are core-drilled at a 5° downward angle toward the outside, avoiding studs, plus a 1" drain hole at the same slope; the drain line must end in open air or a dedicated drain. Clearances: 4" on the left, right and below, 8" above, and away from curtains, furniture and plants. Do not install in laundry or wet rooms, or in an unventilated room smaller than 43 ft². Power is a grounded 115V outlet on a 15 A breaker, with no extension cord. Clean the filters about every three weeks.

MRCOOL's limited warranty covers parts for 1 year and the compressor for 1 year, with no registration required. If a failure in the first 12 months is verified and documented by a licensed HVAC professional, the unit qualifies for full replacement. It is non-transferable, assigned to the original, registered owner, and does not cover labor. Full terms, registration steps and exclusions are in the MRCOOL warranty document under Resources.

About MRCOOL
MRCOOL designs heating, cooling and water-heating equipment from its home base in Hickory, Kentucky. The range runs from DIY ductless mini-splits, built around MRCOOL's patented pre-charged Quick Connect line sets, through contractor-installed mini-splits, central split systems, packaged units and gas furnaces, to HeatWise water heaters and CoolBlade HVLS fans for warehouses and shops.
The Monoblock MTHP Series is MRCOOL's single-room heat pump with no outdoor unit: the whole refrigeration system sits in one cabinet on an exterior wall and breathes through two holes in that wall. It sits beside MRCOOL's ductless mini-splits as the option for rooms where a condenser cannot be placed outside, and it runs on a standard 115V circuit.
