The MRCOOL Universal inverter heat pump condenser is the outdoor half of a Universal central split system, built around a DC inverter compressor and R-454B refrigerant. It is matched to the Universal UAH multi-position air handler of the same capacity, from 24,000 to 60,000 BTU, reaches up to 18.6 SEER2 with the 24,000 BTU pair and is rated for 100% heat output at -13°F.
Order it on its own when the matching Universal air handler is already in place or bought separately. Installation is by a licensed HVAC contractor.
Features
Matched to the Universal Air Handler
Each condenser is rated with the UAH air handler of the same capacity, for example UHP18048-O with UAH18048-O.
Heat Down to -22°F
Outdoor operation runs from -22°F to 122°F, with 100% heat output rated at -13°F.
Cold-Weather Protection
A chassis heater and a crankcase heater are standard, and an electronic expansion valve meters the refrigerant.
Inverter Compressor
Rotary or twin-rotary DC inverter compressors by size modulate output; outdoor sound is rated from 59 dBA (24,000 BTU) to 65 dBA (48,000 BTU).
Side-Discharge Cabinets
The 24,000 BTU cabinet is 26.5" tall and the twin-fan 60,000 BTU cabinet 52.48" tall, all in dark gray.
Pre-Charged Line Option
Accepts MRCOOL's optional No-Vac Quick Connect line sets charged with R-454B, or contractor-supplied 3/8" x 3/4" copper.

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.
Pairs with the Universal UAH air handler of the same capacity. Refrigerant lines are 3/8" liquid and 3/4" suction and are not included. The factory charge covers 24.6' of line, plus 0.7 oz of R-454B per additional foot, up to 164' (24,000 and 30,000 BTU) or 246' (36,000 to 60,000 BTU), with a maximum height difference of 82' or 98.4'. Power is 208/230V single phase; circuit sizes are in the Specifications tab.

It requires purchase from an authorized dealer, installation by a professional installer to all applicable codes, policies and licensing requirements, and the matched, approved Universal UAH air handler. Full terms, registration steps and exclusions are in the MRCOOL warranty document under Resources.
Warranty claims. MRCOOL handles warranty claims directly through support.mrcool.com or (270) 366-0457. Some MRCOOL warranties cover the original purchaser only. Systems that aren't DIY need a valid installation invoice to open a claim.
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.
