The MRCOOL Universal Series 36K Air Handler is designed to deliver dependable, energy-efficient comfort throughout the year. Built to perform in both hot summers and cold winters, this compact unit works efficiently to maintain consistent indoor temperatures while reducing energy usage, helping to keep utility costs under control.

Engineered for versatility, the 36K Air Handler supports multiple installation configurations, including upflow, downflow, and horizontal. Its slim profile makes it a practical solution for tight spaces such as attics, closets, or crawlspaces. To simplify installation, the unit is compatible with the MRCOOL Quick Connect line set (sold separately), which eliminates the need for vacuuming or flaring. For enhanced performance in colder climates, it can be paired with optional Universal Series Heat Kits, providing added heating capacity and emergency backup when needed. At the core of the system is an M-shaped evaporator coil with a large surface area that improves airflow and maximizes heat transfer. Constructed from 100% aluminum, the coil resists corrosion for long-term durability. Despite its powerful output, the air handler operates quietly, ensuring comfort without disruption.
