Hi everybody. I need to replace our existing, officially dead A/C
system before Summer gets serious here in Orlando. I've gotten 3
quotes & am down to just a couple questions. Hopefully you guys can
help.

1) Size. House is 1345 sg ft, in high heat & humidity Florida. I
cannot tell the size of the existing unit & have been told it's 3 ton
or 2.5 depending on who I talk to. I have been quoted on both 3 ton &
2.5 ton. The guy suggesting the 2.5 says longer cycles will control
humidity better & the guys suggesting 3 says it will get on top of the
heat better in broiling July. In all cases a 3 ton variable speed air
handler would be used. Suggestions?

2) Trane vs. Carrier. The 3 possible systems are: 1)Trane XR13 3 ton
with 410 refrigerant & 4TEE3F37B air handler. 2) Carrier 25HCA36 3 ton
with FV4BNF003 air handler. 3) Carrier 25HCA330A003 2.5 ton with
FV4BNF003 air handler. I've been told by the Trane guy that his is a
much better unit. I've been told by the Carrier guy that the entry
level Trane was not designed for the higher pressures of 410 & is a
potential leaker. Carrier also said their air handler is much tighter
& will not draw hot air from the garage where its located.

If it was your house, would you go Trane or Carrier & 3 ton or 2.5?

Thanks in advance for the advice.

Confused in Florida.

A proper 'load calculation' will solve this battle.

Equipment bashers are NOT the people you want to deal with. Get one that
understands that a proper installation is the key, to the longevity of ANY
system.

Niether, I would install the brand I sell everyday. :-)

You're welcome.

OK This is getting interesting. Let's assume I want to go with a
better quality brand since we're staying in the house for many years.
Sounds like I also need to assume that the Trane and Carrier will both
handle 410 just fine and the "tightness" of the air handler is a non-
issue. I still don't know what size to use, how to do a "load
calculation" or which brand is the better performer. It's already 85
degrees outside & I really don't want to get another 3 quotes.

        Yep.

        The load calc is an analysis performed by the contractor,
called a Manual J and Manual D. J is for sizing the system 'to
standards', and D is for sizing the ductwork.

        In reality, there just isn't that much difference between the
2.5 and the 3 , most especially since you've decided on a variable
speed air handler. Personally, I would go with the 3 - I like having
extra capacity on peak days.

        The Carrier dealer is already out of the picture for lying, so
that leaves the Trane guy, or someone else.
