The MRCOOL® Signature Series 30k Multi-Position Air Handler is engineered to provide powerful, efficient comfort in any season. Featuring advanced R-454B refrigerant, this system meets modern environmental standards while helping reduce your energy use and carbon footprint without compromising performance. Its multipositional capability allows for flexible installation in upflow, downflow, or horizontal configurations, making it a smart fit for new builds, remodels, or system upgrades. The slim, compact design makes it ideal for tight spaces such as closets, attics, or crawlspaces, while still delivering full heating and cooling power when paired with a compatible MRCOOL® condenser or heat pump. Built for long-term performance, the air handler includes a durable galvanized steel cabinet, a high-efficiency ECM blower motor, and copper “A” coils with enhanced aluminum fins for excellent heat transfer and humidity control. Internal thermal insulation helps reduce condensation and energy loss, supporting quieter operation and greater efficiency. Installation is simple and cost-effective, with a design that minimizes labor time. A built in air filter rack makes regular maintenance fast and easy, and an optional electric heat kit adds extra comfort for colder climates. The unit is fully compatible with most third-party smart thermostats, giving homeowners the freedom to control comfort with the platform of their choice. Protected by a 10-year limited parts warranty, the MRCOOL® Signature Series 30k Multi-Position Air Handler is a reliable, space-saving, energy-efficient solution for total home comfort.
