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.
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.

Covered by a 10-year limited parts warranty, the MRCOOL® Signature Series 30K Stud Mount Air Handler is a dependable, space-efficient solution that delivers comfort without compromise.
