York S1-373-27956-405 Indoor Coil

The York S1-373-27956-405 Indoor Flex A-Coil is a York indoor coil listed as an Indoor A Flex Coil TinCoat. An indoor A-coil is the evaporator in a split air conditioning or heat pump system: liquid refrigerant boils inside it, pulls heat and moisture out of the air moving across the fins, and sends cool, dry air to the house. If you are searching for S1-373-27956-405, this is the listing. The TinCoat in the York description marks the tin-coated version of the coil, so do not confuse it with a bare version when you order.

Replacing an evaporator coil is a full refrigerant-side job, and the shop that does it right saves itself a second trip. Recover the charge, cut out the old coil, and install 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. Set the coil so the condensate pan drains properly and seal the cabinet so conditioned air does not bypass the fins. The coil size is not published in this listing, so confirm the dimensions and connection sizes against the nameplate and the old coil before you order.
