Universal Series 36,000 BTU Air Handler
The MRCOOL® Universal® Series 36K Air Handler offers a high-efficiency, performance-driven solution for year-round indoor comfort. Designed to meet the needs of modern homeowners, it’s the perfect upgrade for those looking to reduce energy costs without sacrificing heating and cooling performance. Built for flexibility, the air handler features a multi-position design that allows for vertical, horizontal, or downflow installation. This makes it adaptable to a wide range of home layouts and ideal for tight or limited spaces. Its compact footprint simplifies placement, while compatibility with the MRCOOL® NO-VAC® Quick Connect® line set (sold separately) makes installation even easier. This innovative line set comes pre-charged and sealed, eliminating the need for vacuuming, flaring, or handling refrigerant—saving both time and installation cost. For enhanced functionality, the air handler supports optional Universal® Series Heat Kits, which can boost heating capacity during cold weather or serve as emergency backup heat during unexpected temperature drops. Inside, the system features an advanced M-shaped evaporator coil that increases the surface area for better heat exchange, improved airflow, and higher energy efficiency. Quiet operation ensures it blends seamlessly into your home environment, producing sound levels comparable to everyday conversation or a running dishwasher. The coil is constructed from 100% aluminum for superior corrosion resistance and long-term durability. Backed by a 10-year parts warranty and a 2-year limited labor warranty, the MRCOOL® Universal® 36K Air Handler delivers reliable performance and peace of mind.
