Badger WCHL485AC – 4 Ton Multi‑Position Air Handler R‑454B

The Badger WCHL485AC is a robust 4‑ton indoor air handler built to meet the demands of modern residential HVAC systems with a strong focus on flexibility, performance, and low‑GWP refrigerant compatibility. Designed for multi‑position installation (up‑flow, down‑flow or horizontal), it fits seamlessly into attics, closets, basements or other challenging spaces, making it an excellent choice whether you’re installing new equipment or replacing an older system. According to the manufacturer’s spec sheet, this unit supports R‑454B refrigerant, helping position your system for future regulatory compliance.

Inside the unit you’ll find a high‑efficiency ECM (Electronically Commutated Motor) blower, pre‑painted galvanized steel cabinet with heavy insulation and vapor barrier to reduce condensation, drainable condensate pans built for heavy duty use, and a factory‑installed TXV (thermostatic expansion valve) tailored for R‑454B applications. The cabinet is tested for low leakage rates (less than 2% at 1.0 in‑W.C.) and supports flexible installation configurations including horizontal hanging.

Whether you’re pairing this air handler with a multi‑ton condenser or supplying a new high‑capacity split system, the WCHL485AC offers the durability, adaptability and refrigerant readiness you’d expect from a premium indoor air handler.
