MRCOOL® Universal® 48K Heat Pump Condenser— 4 Ton DC Inverter, R-454B- UHP18048-O

Product Description 

 Model: UHP18048-O

MRCOOL Universal® 48K DC Inverter Heat Pump Condenser — High-Capacity Whole-Home Comfort

The MRCOOL® Universal® Series 48K Heat Pump Condenser (UHP18048-O) is built for larger homes and high-demand applications where performance, efficiency, and reliability matter most. Delivering 48,000 BTU of heating and cooling, this 4-ton inverter condenser maintains consistent comfort through extreme summer heat and bitter winter cold.

With an efficiency rating of up to 17.5 SEER2, the Universal 48K provides a major efficiency upgrade over older fixed-speed systems—helping reduce energy consumption without sacrificing output. The system operates on next-generation R-454B refrigerant, making it compliant with modern efficiency standards and future HVAC regulations

 

 

DC Inverter Technology That Works Smarter, Not Harder

At the heart of the Universal 48K is advanced DC inverter technology, allowing the compressor to automatically modulate output instead of constantly cycling on and off. This delivers:

• Stable indoor temperatures across larger spaces
• Improved energy efficiency at partial loads
• Reduced noise and vibration
• Longer system life through minimized component stress

 

Despite its high capacity, the condenser maintains a controlled 65 dBA sound level, making it suitable for residential neighborhoods and large-home installations.

 

 

Flexible Installation for Large Homes & Replacements

The MRCOOL Universal 48K features a compact outdoor footprint for its size and supports an extended 246-ft maximum line set length, giving installers exceptional flexibility for retrofits, replacements, and challenging layouts.

When paired with the optional MRCOOL NO-VAC® Quick Connect® line set (sold separately), installation is faster and cleaner—no vacuum pumps, flaring tools, or refrigerant handling required. This reduces labor time, complexity, and overall install cost.

 

 

Built to Last — Backed by MRCOOL

Like all Universal Series systems, the 48K condenser is backed by a 10-year parts warranty and a 2-year limited labor warranty, ensuring long-term confidence from one of the most trusted names in HVAC.
