York S1-373-27956-407 Indoor Coil

The York S1-373-27956-407 Indoor A-Flex Coil is a 2-row York Source 1 indoor coil with a 20 in. high by 17 in. wide coil face. In the photo it shows a galvanized top, a cream-colored drain pan, a bent copper line and a brass fitting with a black cap. Older listings and cross-references may show this coil under the number S1-373-27956-007, so if that is the number you have been searching for, S1-373-27956-407 is the one to order.

Coil size is how you match a replacement, and three numbers do the work: rows, height and width. Rows is the number of tube rows the air passes through, while height and width are the dimensions of the coil face. This coil is 2 rows, 20 in. high and 17 in. wide. More rows put more heat-transfer surface in the airstream and add capacity, but they also add air-side resistance, so a coil is matched to the blower and duct system it was designed for. If you need a larger three-row option, compare our S1-373-27956-417, which is 3 rows and 22 in. high by 24 in. wide.

Treat it like the freight item it is. This coil ships by truck, so have someone on site to receive it and look it over for bent fins or crushed tubing before you sign off. Leave the cap on the brass fitting until you are ready to make the connection. On the install, pressure test and evacuate the system, replace the filter drier, and make sure the drain pan and condensate line are clear and pitched to drain, because a coil that holds water breeds problems. Use the refrigerant and metering device the system was designed for. Send us the model and serial number from the air handler or furnace nameplate and we will confirm the match before you buy.
