York S1-373-27956-406 Indoor Coil

The York S1-373-27956-406 Indoor Flex A-Coil is a York indoor coil listed as a 2R 24H 17W A Indoor Coil Flex. An indoor A-coil is the evaporator in a split air conditioning or heat pump system: liquid refrigerant boils inside it, absorbs heat and moisture from the air crossing the fins, and delivers cool, dry air to the house. The York designation reads 2R 24H 17W, which is the coil's row count, height and width as York lists it, and it is the quickest way to tell this coil apart from the others in the series. If you are searching for S1-373-27956-406, this is the listing.

Replacing an evaporator coil is a full refrigerant-side job, and doing it by the book saves a second trip. Recover the charge, remove the old coil, and set the new one with the correct metering device for the system. Change the liquid-line filter-drier, braze with nitrogen flowing, pressure test, pull a deep vacuum, and weigh in the charge. Make sure the condensate pan drains and seal the cabinet so air cannot bypass the fins. Compare the 2R 24H 17W designation with the nameplate or tag on the coil you are replacing, and confirm the connection sizes before you order.
