Overview

Product Overview

Upgrade your HVAC system with the MRCOOL® Signature Series 30K Stud Mount Air Handler—engineered for superior adaptability, energy efficiency, and straightforward installation. Designed to install neatly between standard wall studs, this compact unit is ideal for tight or unconventional spaces where traditional air handlers aren’t an option, making it a versatile solution for various applications.

Despite its space-saving design, this air handler delivers reliable heating and cooling when paired with a compatible heat pump or condenser. It offers flexible airflow configurations with both front and bottom return options to meet the needs of your specific installation.

Constructed from durable galvanized steel, the MRCOOL® Signature Series 30k Stud Mount Air Handler is built for long-term performance. Advanced blower technology ensures quiet, consistent operation, while full cabinet insulation minimizes energy loss and condensation. The high-efficiency ECM motor promotes steady, even airflow and helps reduce energy consumption.

Routine maintenance is a breeze thanks to the built-in filter rack, and optional electric heat kits are available to enhance performance in colder climates.

Covered by a 10-year limited parts warranty, this unit offers lasting peace of mind. Whether you're remodeling, replacing old equipment, or adding a new unit, the MRCOOL® Signature Series 30K Stud Mount Air Handler is a dependable, space-efficient solution that delivers comfort without compromise.

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.
