NON DIY - Licensed HVAC Installation
Description
The MRCOOL® Signature Series 18k Multi-Position Air Handler delivers dependable, year-round climate control with enhanced energy efficiency thanks to its use of R-454B refrigerant, an eco-friendly upgrade that reduces environmental impact without sacrificing performance.
Built for flexibility, this unit supports upflow, downflow, and horizontal configurations, making it an excellent choice for compact installations such as closets, attics, and crawl spaces. Despite its slim profile, the Signature Series Air Handler provides robust heating and cooling when matched with a compatible heat pump or condenser.
Its tough galvanized steel cabinet resists wear and corrosion for long-term durability. Inside, copper “A” coils with high-efficiency aluminum fins maximize heat transfer and moisture removal, while internal thermal insulation reduces energy waste and condensation.
Installation is streamlined with a user-friendly design, saving time and labor costs. A built-in air filter rack allows for quick filter changes, and an optional electric heat kit is available for enhanced performance in colder climates.
Smart home ready, this unit works with most third-party thermostats, giving homeowners control flexibility without requiring proprietary systems. Backed by a 10-year limited parts warranty, the MRCOOL® Signature Series 18k Multi-Position Air Handler delivers strength, efficiency, and adaptability for powerful, reliable comfort all year long.
