have to replace HVAC system & need help
ok, have tried reading through forums to answer my questions, but need further help. We need to replace our complete hvac system, currently have a carrier 5t, 12 seer, outdoor unit 10 years old, indoor unit 15 yrs old, both with parts replaced and now coils not working correctly and losing freeon.
pertinent info: live in San Antonio, Tx - hot humid with a good 5 months of the year 95+ and humidity pushing that over 100. Just over 2000sq ft with open plan loft & high living area ceilings. Furnace(gas) located in attic and is horizantal. Current dimensions of said unit : 91.5", ht 22 5/8; widest measurement 34 6/8". (have been told during 1 quote that there is only about 4" between coils & furnace in current configuration. Attic access 52x23.
My questions (so much conflicitng info) I have 3 quotes for 3 different systems - which one will fit in such tight space and is best buy.
quote #1 Carrier Bryant preferred models 116BNA060; 313AAV060110; CNPHP6124ATA priced at $12449 incl with 10 year parts warranty ( will give back $427 on parts installed less than 2 weeks ago)
quote #2 Trane XL16i (16S/13E) model #'s 477X6060L100A; 4TXCD063BC3HCA;TUDC100B9V5VB priced @ $9000 with 10 year labor and parts warranty (12 year compressor).
quote #3 Carrier Comfort Series 2 stage ECM boost 16.5 SEER/13 EER (did not get indiv. model #'s) priced @ $7986.34 with 10 yr parts warranty.
I apprecaite your help, all 3 techs have seemed knowledgable - quotes 1 & 2 only carry brand quoted. Did not seem to find accessibility to furnace as an issue. Quote 3 has all 3 brands + others but on measuring says this unit quoted would provide best efficiency and fitting with ducts.
Really appreciate and help and input and have tried to give all pertinent information.
