Matching condenser & air handler
I am installing a split-system ducted AC in my space-constrained NYC co-op. We are using Aerosys THDC-30 condensers in the window but now we need to match them up with the proper air handlers. The manufacturer will only certify two air handlers to work with that unit and to achieve SEER 12 (space-constrained units need a minimum of 12 SEER, not 13): Carrier FV4C 005, and Rheem RHBP-21.
The Rheem is 36" long compared to Carrier's 53.5", so to save space we'd prefer the Rheem -- Can anyone offer a comparison of the units in terms of quality, quiet, performance, etc?
Lastly, Carrier makes a smaller version of its handler, FV4C 002 -- but Aerosys hasn't tested that unit against its condenser and won't certify it. Since it's smaller, they suspect it won't work at the required SSER... does anyone have experience with this match-up? I've heard anecdotally that it works fine, I've also heard there have been problems with that combination.
