About this product

The MRCOOL® Signature Series 36k Multi-Position Air Handler delivers dependable, energy-efficient comfort in any season. With the addition of environmentally friendly R-454B refrigerant, this system supports cleaner standards while helping to lower energy costs and reduce your home's carbon footprint. Designed for flexibility and space efficiency, the unit can be installed in upflow, downflow, or horizontal positions, making it an ideal choice to accommodate a wide variety of residential layouts. Its compact, modern design allows it to fit easily into tight areas like attics, closets, or crawl spaces without sacrificing performance. When paired with a compatible heat pump or condenser, it provides powerful, year-round heating and cooling. The air handler features a durable galvanized steel cabinet, a high-efficiency ECM blower motor, and copper “A” coils with enhanced aluminum fins for optimized heat transfer and humidity control. Internal thermal insulation minimizes energy loss and condensation, improving both comfort and efficiency. Installation is straightforward and designed to reduce labor time and complexity. A built in air filter rack makes maintenance quick and convenient, while an optional electric heat kit enhances performance in colder climates. For smart home convenience, this unit works seamlessly with most third-party thermostats, giving you the freedom to choose how you control your comfort without being locked into a specific brand. Backed by a 10-year limited parts warranty, the MRCOOL® Signature Series 36k Multi-Position Air Handler offers lasting performance, efficient operation, and flexible installation for total home comfort.
