Hi all,
A few years back our 5 ton air handler went out on an ancient 5 ton 10 seer rheem classic heat pump. The home warranty service sent out a crew and the replaced the handler with a Carrier FB4CNP060. The system runs great but uses a ton of electricity.
I wanted to get something more efficient. I asked for a few quotes to have someone place a new more efficient heat pump condensor, ideally the highest efficiency possible. The air handler is down flow in an easy access closet and the condensor is on a pad 10 ft away outside with an easy access crawl space where the lines are.
Two company’s said you could not just replace the condensor alone or the system would be no more efficient than what I have because they are not matched. Both quoted the air handler and the condensor plus install for a 20 seer system to be one boatload of money.
Another gentleman came today and said i could use the new air handler and upgrade the condensor.
He said you couldn’t put a two stage condensor with that single stage airhandler, but something with a single stage and a higher efficiency could work. Furthermore it did not have to be a Carrier. He quoted me a reasonable price to swap out the old 10 seer compressor to a new rheem classic 5 ton 14 seer compressor. Roughly 1/3 of the boatload of cash the others wanted.
I asked him if I could do something more efficient. He later called back and said he did some digging and found a 20 seer Bosch 2.0 with a variable speed condensor would work with my air handler. He could do that for just a bit more. That sounds attractive.
My question lies in if I should or can be pairing these condensors with the Carrier FB4CNP060 air handler. It seems a shame to throw out that one as it is working and relatively new.
It’s just that it’s now 2 to 1 on the professional opinions. I just want to upgrade that noisy energy eating dinosaur outside.
Thanks!
