Reading the model number
ML is Lennox's Merit line, and 17 is the nominal SEER2 class for the ML17KC2 series. K is R-454B, C is an air conditioner, 2 is the two-stage compressor, 036 is 3 tons, and 230 is 208/230V single-phase. The characters after 230 on the unit label are Lennox revision codes. The AHRI Directory lists it as ML17KC2-036-230A**.
What it pairs with
The AHRI Directory lists this unit with Lennox CK40CT, CK40DT, and CK40HT coils on Lennox gas furnaces, and with CBK45UHET, CBK45UHPT, CBK45UHVT, and CBK47UHET air handlers. The best listed match with equipment we carry, a CK40HT-51/61C-71 coil with an ML180UH110V60C furnace, reaches 17 SEER2.
R-454B systems need a refrigerant detection sensor at the indoor unit. Lennox installs it at the factory or in the field, so confirm your coil or air handler has one.
Sizing and fit
Size it from a Manual J load calculation, and treat your old unit's tonnage as a starting point only. If you're keeping your indoor coil, check that it appears in an AHRI listing with this unit before you order.
It cools down to 45°F outdoor air without extra controls, and Lennox's optional low ambient kit takes it down to 30°F.
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.
