About the UAH18048-O
MRCOOL 4 Ton Universal Air Handler – UAH18048-O
The MRCOOL® Universal® Series 48K Air Handler is a high-efficiency HVAC solution engineered to deliver consistent, year-round comfort while helping homeowners cut down on energy costs. Whether you’re upgrading an aging system or installing new equipment, this unit offers the ideal combination of performance, efficiency, and reliability.
Designed with installation flexibility in mind, the Universal® 48K supports multiple configurations—including vertical, horizontal, and downflow setups—making it a versatile fit for a wide range of spaces. Its compact design allows for seamless placement in tight or unconventional areas. For added convenience, the unit is compatible with the MRCOOL® NO-VAC® Quick Connect® line set (sold separately), which arrives pre-charged to eliminate the need for vacuuming or flaring—significantly simplifying installation and saving on labor.
The system also supports Universal® Series Heat Kits, offering increased heating capability during cold weather and providing peace of mind with emergency backup heat when needed.
Inside, the air handler is equipped with an advanced M-shaped evaporator coil that maximizes surface area for heat exchange, enhances airflow, and improves overall system efficiency—all while keeping the unit lightweight. Built from 100% aluminum, the coil is corrosion-resistant, ensuring long-term durability with minimal maintenance.
Operating at quiet sound levels similar to a household conversation or dishwasher, the Universal® 48K blends comfort with discretion. Backed by a 10-year parts warranty and a 2-year limited labor warranty, this air handler is a smart investment in your home’s comfort and efficiency.
