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.
