- Cabinet: C size, 21 inches wide

Reading the model number
The first C means indoor coil, K means R-454B compatible, and 40 is the Quantum coil series. The D after 40 is the downflow cased cabinet, T is the factory expansion valve, 48 is the 4 ton size, C is the 21-inch cabinet that matches C furnaces, and 01 means an R-410A expansion valve is installed.
What it pairs with
It lines up with Lennox furnaces that carry the C cabinet letter. As shipped, it's set up for R-410A. The air conditioners and heat pumps we sell use R-454B, so pairing it with one needs Lennox's R-454B expansion valve and refrigerant detection parts, ordered separately.
Sizing and fit
Choose the size to match your outdoor unit's tonnage, and the cabinet letter to match your furnace. Have your outdoor unit's model number ready when you call, and we'll check it against Lennox's AHRI matchups.

HVAC USA is an authorized Lennox reseller, and everything we sell is new factory equipment. Your full Lennox warranty applies when a licensed, manufacturer-certified contractor installs your system and registers it within 60 days.
