oh sorry .. for clarification.. the customer WANTS unit replaced .. so that is what i meant fir match.. york affinity 2 stage hp high eff... ive done a couple when i worked for a york guy .. but that was years ago
Acadia and York agreed to that match up. As far as i know all Arcadia's used a York air handler.
Any York 2 stage heat pump will match up to the air handler. May have to add more strip heat though.
