Reading the model number
The first C means indoor coil, K means R-454B, and 40 is the Quantum coil series. The C after 40 is the upflow cased cabinet, T is the factory expansion valve, 30/36 is the 2.5 to 3 ton size, A is the 14.5-inch cabinet that matches A furnaces, and 71 means R-454B only. You may also see it written as CK40CT-30-36A-71.
What it pairs with
It lines up with Lennox furnaces that carry the A cabinet letter. The AHRI Directory lists it with these Lennox units we sell: EL15KC1, EL16KC1, EL18KCV, EL22KCV, ML13KC1, ML14KC1, and ML17KC2 air conditioners and EL19KPV heat pumps. The best listed match we carry is the EL22KCV-024-230 air conditioner on an EL280UH045E36A furnace, at 20.25 SEER2.
Sizing and fit
Choose the size to match your outdoor unit's tonnage, and the cabinet letter to match your furnace. If your furnace has no built-in RDS mitigation control, it needs Lennox's RDS blower control board, ordered separately. Have your outdoor unit's model number ready when you call, and we'll check it against Lennox's AHRI matchups.
Warranty and registration
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.
