13 SEER air handler with a 10 SEER condenser

[ctharr]

I would greatly appreciate it if someone could email me the article as well. I'm just a homeowner who is trying to learn as much about this as possible because my home warranty company is planning to replace my home's original air handler (York Model G+HC030AA from 1987 which uses R22) with a new 13 SEER Payne air handler (not sure of the specific model yet) which uses R410A. I have a two-fold concern with their plan of leaving the 10 SEER York compressor (Model E4FD030S06A) in place because of 13/10 SEER mismatch as well as the R22/R410A mismatch. I realize this thread is about the 13/10 mismatch article, but in addition to that help any advice you can give me about how to handle the concerns I also have with R22/R410A mismatch with the service company and home warranty company is appreciated.

I wouldn't worry about it.

The 13 + 10 = 8 is related to a high seer outdoor, and a low seer indoor.

You have the opposite. A high seer indoor, with a low seer outdoor.
Granted, coils technically don't have a "seer" rating.

Alot of manufacturers make their units to handle both refrigerants, even though the model shows as a "r410" unit. The only thing that would be required would be to change the orfice to the correct size, or in this case, I would suggest using a TXV (thermostatic expansion device) since it may be difficult to find the correct size orfice.

If the Payne air handler has a 410 TXV, you cannot put it on a 22 outdoor unit. They would need to replace the TXV to one that is for 22 and make sure the outdoor unit had a hard start kit of not a scroll compressor. Knowing York on a 10 SEER, it likely is a recip.
