Overview

Product Overview

Transform your HVAC system with the MRCOOL® Signature Series 24K Stud Mount Air Handler—crafted for maximum flexibility, energy efficiency, and hassle-free installation. Designed to fit cleanly between standard wall studs, this compact unit is perfect for tight spaces where conventional air handlers just won’t work, making it a smart choice for a wide range of installations.

Despite its slim profile, this powerful unit delivers dependable heating and cooling performance when paired with a compatible heat pump or condenser. With both front and bottom return air options, it adapts easily to your layout and airflow requirements.

Built to last, the MRCOOL® Signature Series 24k Stud Mount Air Handler features a tough galvanized steel cabinet and advanced blower technology for quiet, efficient operation. Full insulation throughout the cabinet minimizes energy loss and prevents condensation, while the high-efficiency ECM motor ensures steady airflow and reduced utility bills.

Maintenance is simple with an integrated air filter rack for quick filter replacements. For colder climates, optional electric heat kits are available to provide added warmth when needed.

Supported by a 10-year limited parts warranty, this unit offers reliability and peace of mind. Whether you're renovating, upgrading, or building new, the MRCOOL® Signature Series 24K Stud Mount Air Handler delivers compact 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.
