MRCOOL® Signature Series 36k Multi-Position Air Handler
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.
Built for Flexibility
Its multi-positional capability allows installation in upflow, downflow, or horizontal configurations, making it a flexible solution for new builds, remodels, or system upgrades. The slim, compact design fits easily into 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.
Long-Term Durability
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.
User-Friendly Design
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.
