The MRCOOL Universal central heat pump split system pairs a variable-speed inverter condenser with a multi-position air handler of the same capacity, in five sizes from 2 to 5 tons on R-454B refrigerant. It reaches up to 18.6 SEER2 on the 24,000 BTU pair and is rated to operate in outdoor air from -22°F to 122°F, heating and cooling the whole house through its ductwork.
It suits a homeowner replacing a central air conditioner, heat pump or furnace with an all-electric system on the existing ducts. Installation is by a licensed HVAC contractor.
Features
Matched Condenser and Air Handler
Each system pairs a UHP condenser with the UAH air handler of the same capacity, for example UHP18036-O with UAH18036-O.
Cold-Climate Inverter
Rated for 100% heat output at -13°F and outdoor operation down to -22°F, with a chassis heater and crankcase heater fitted as standard.
Efficiency
Up to 18.6 SEER2, 12 EER2 and 10.8 HSPF2 in Region IV, depending on size, with ENERGY STAR ratings on every pair.
Four-Way Air Handler
Installs upflow, downflow, horizontal left or horizontal right, and its 14.49" to 21.5" width suits a typical furnace closet.
Automatic Voltage Detection
The air handler runs on 115V, 208V or 230V and detects the supply on its own.
All-Aluminum M-Coil
The indoor coil is an M-shaped all-aluminum heat exchanger, paired with a symmetric blower for steady airflow.
Heat Kit Ready
Optional slide-out electric heat kits from 5kW to 20kW add emergency heat inside the air handler.

Installation
Professional installation required. This equipment must be installed by a licensed HVAC contractor (EPA Section 608-certified for any refrigerant work), following MRCOOL's installation manual and all local codes, permits and licensing rules. MRCOOL's limited warranty applies only to units installed that way, and it does not cover installation labor.
Refrigerant lines are 3/8" liquid and 3/4" suction and are not included. The factory charge covers 24.6' of line; beyond that the contractor adds 0.7 oz of R-454B per foot, up to a maximum length of 164' (24,000 and 30,000 BTU) or 246' (36,000 to 60,000 BTU) and a maximum height difference of 82' or 98.4'. The air handler is for ducted use only, with an external static pressure range of 0 to 1.0 in. w.c. (24,000 to 36,000 BTU) or 0 to 0.8 in. w.c. (48,000 and 60,000 BTU). Filter sizes are 12" x 20" x 1" (24,000 BTU), 16" x 20" x 1" (30,000 and 36,000 BTU) and 20" x 20" x 1" (48,000 and 60,000 BTU). A 24V thermostat is needed and is not in the packing list; circuit sizes are in the Specifications tab.

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 Universal Split is MRCOOL's contractor-installed central heat pump on R-454B: a variable-speed UHP condenser matched to a UAH multi-position air handler of the same capacity. The pair is sold together as a system or as separate units, and optional Universal electric heat kits slide into the air handler. MRCOOL's No-Vac Quick Connect line sets, which arrive charged with refrigerant, are an optional alternative to field-brazed copper and are sold separately.
