2 Ton GrandAire R454B Variable Speed Air Handler, WCVL245CB
The GrandAire WCVL245CB is a compact 2 ton variable speed air handler. It's the indoor half of Grandaire's matched 18.3 SEER2 inverter heat pump system. Its 17.5-inch-wide multi-position cabinet fits tight closets, attics, and crawlspaces, and its constant-airflow ECM 2.0 blower holds steady airflow up to 0.80 in. W.C. external static pressure. An electronic expansion valve and all-aluminum coil handle R-454B with precision, and the cabinet runs on 115V or 208/230V power. Pair it with the GrandAire W5H9V24AKAAA 2 ton inverter heat pump and add a GrandAire 5kW breakered heat strip for backup heat. Shop all variable speed air handlers.
Is a 2 Ton Air Handler the Right Size?
The WCVL245CB is built for 2 ton systems serving condos, apartments, small homes, and additions. Its airflow, coil, and electronic expansion valve are sized to the matched W5H9V24AKAAA outdoor unit, so the indoor and outdoor capacity work as one tuned system rather than a mix-and-match combination.
Beyond tonnage, check the installation space and ductwork. The cabinet measures 17.52" W x 21.02" D x 45.00" H, and the ECM blower compensates for moderate duct restriction. Undersized returns or crushed flex duct will still hurt comfort and efficiency. Consider supply voltage too: the blower runs on 115V, but electric heat requires 208/230V.
Ideal for: Closet and attic installs in condos, apartments, and small homes, and multi-family retrofits that need a narrow 17.5" cabinet and a matched 2 ton inverter heat pump.
Need more capacity? Step up to the 3 Ton GrandAire R454B Variable Speed Air Handler, WCVL365CC for mid-size homes on a 3 ton system.
