Overview

Product Overview

The MRCOOL® Universal® Series 30K Air Handler is designed to deliver dependable comfort and energy-saving performance for homes that demand efficient climate control. Whether you're upgrading from an outdated system or installing new HVAC equipment, this air handler offers a perfect balance of reliability, versatility, and long-term value.

Its flexible multi-position design supports upflow, downflow, and horizontal installations, making it ideal for a wide range of applications and layout configurations. The compact footprint allows the unit to fit easily into tight or unconventional spaces such as closets, attics, or mechanical rooms—perfect for maximizing usable space in modern homes.

For a streamlined and efficient installation process, the 30K Air Handler is fully compatible with the optional MRCOOL® NO-VAC® Quick Connect® line set. This pre-charged system eliminates the need for vacuuming or flaring, saving time and labor while reducing the chance of installation error. The unit is also designed to work with MRCOOL® Universal® Series Heat Kits, which enhance heating output in colder climates and provide emergency backup heating when needed.

Inside, a space-saving M-shaped evaporator coil increases the surface area for improved heat exchange and airflow. Constructed entirely from 100% aluminum, the coil is corrosion-resistant and built for long-term durability. Quiet operation ensures minimal disruption, making the unit suitable for installation near bedrooms and living spaces.

For added peace of mind, MRCOOL® includes a 10-year parts warranty and a 2-year limited labor warranty—offering lasting protection for your investment.

Manufacturer Warranty

Covered by MRCOOL's limited warranty. Warranty terms are set by MRCOOL and differ by product line — whether registration is required, and whether the installation has to be performed by a state-licensed HVAC contractor, is not the same across the range. In every case coverage depends on the unit being installed according to MRCOOL's instructions and all applicable codes and permits. MRCOOL's warranty document for this model is the controlling source; ask us and we'll send you the one that applies.

Professional Installation Recommended

Most HVAC equipment must be installed and connected by a licensed professional to remain safe, code-compliant, and eligible for manufacturer warranty coverage. If you're unsure about installation requirements, contact us before you order.

Before You Order

Make sure it is the right size, and that you have the rest of it

Most outdoor units ship alone. If you are not certain of the capacity, or of what has to go with this unit, these two will work it out with you.
