    Confused Too many choices - need some help, Please

    Good Morning,

    I should note that we live in Florida, as that may be relevant to my questions.

    We have just received a quote from a dealer/service company in our area. This company has an excellent reputation, but I am not sure if their salesman is trying to sell us a "Mercedes", when we really don't need one.

    The quote includes pricing for 2 different systems, both Carrier. One is for the Infinity 25HNA6 with FE4 air handler and the other is for 25HCA3 with FV4 air handler. We asked him about a straight A/C system with heat strips for heating, since we don't use the heat that much. (This was recommended by a service tech, who had been at our home previously). The salesman told us that was a bad idea, and that we should definitely stay with the heat pump.

    I do want a good efficient system that will work well and save us money on our electric bill, but I don't want to overspend on something that we will probably have to replace again, in another 10+ years.

    Any input you could provide, would be greatly appreciated. I would also like opinions on other reliable name brand systems, as we really don't have a clue. This guy said that Carrier and Trane are the best.

    Thanks...in advance...for your assistance.

    Tampa and north,go wth a heat pump,unless you are one of the few that doesn't run the heat very much.

    Cool-Cash Rebates from Carrier should bring the Infinity price down at this time.

    Both systems have dehumidification controls,the Infinity is the superior one.

    What city are you in??

    We are in Clearwater.

    Also...Carrier has 3 systems: Comfort, Performance and Infinity. Is there any reason that we should not consider either the Comfort or Performance series instead of the Infinity?

    We were faced with the same decision and as we had to replace 2 systems --we ended up going with the Carrier Performance line and the FV air handlers. We have been been very satisfied with our choice.....and.....the outside units are quiet.

    Were we plannng on staying in our house more than three or four years, we might have gone with the Infinity system. However, the price differential and the bias towards having 2 systems (one up and one down) where we live made this a better choice for us rather than one complicated zoning deal.

    We are very happy with our choice.

    I might add that we live between New Orleans and Biloxi. We used heat strips before. We now have heat pumps and a TINY electric bill when we have these cold snaps. Best of all, we set it and forget it, and keep the house comfortably warm 24/7. With electric rates going up all the time---I would encourage you to get a heat pump. The electric rates are going to rise faster than your new system will age.

    We did not go with the high seer numbers but our bills have dropped significantly. Three winter bills for COLD winter months averaged $62 for a 2400 sq. ft ...ALL ELECTRIC.... house. (We do have gas hot water ---only non-electric utility).

    No,but the Infinity will give you the lowest indoor humidity,which improves comfort and reduces possiblities of mold and allergens.The two stage compressor,runs more at low stage,and removes more moisture.

    Performance may be higher SEER then Infinity in some sizes.Comfort is less SEER and the outdoor unit in louder,if it's location makes that a concern.

    Infinity air handler and control can be used with any of these.

    Use the search function on this site ,Infinity,to see what other homeowners think of theirs.Here in Florida our customers find the incresed comfort allows them to raise the indoor temperature,do to lower humidity.No "stickey" sheets and no need to lower the temp. in mild weather to feel comfortable.

    I agree with Doral. Based on your location, you are on the bubble as to a heat pump vs a straight AC system.

    As a compromise to a two stg Infinity system, I also recommend the Carrier Performance 15 paired with matching var speed air handler. You could include the Infinity controller or the less expensive Thermidistat. The Performance 15 has very solid numbers in the AC or the heat pump model. Here are the numbers for a three ton AC system and HP system just as examples.

    1249721 Active OEM PERFORMANCE 15 PURON AC CARRIER AIR CONDITIONING 24APA536A30 FE5ANB004+UI 36400 13.20 16.00

    1125695 Active OEM PERFORMANCE 15 PURON HP CARRIER AIR CONDITIONING 25HPA536H30 FV4BNB006 36000 13.00 16.00 36000 9.30 21800

    good BTUs,great EER and SEER.

    IMO

    I should have added that we have the newer EDGE thermostat that is programmable. It does have a humidity reading on it and you can set the desired humidity level to "dehumidify". I am not really high tech and I find this thermostat very easy to understand. However, I have seen some installers/experts (I am just a homeowner) say that they prefer the older Thermidistat.

    Our stat gives outdoor & indooor temp and also give humidity reading. I am still a bit confused why some prefer the older style as I have heard that it makes a clicking noise. However, we are satisfied with what we have.

    Thank you all for your input and advice. Making the right decision can be a daunting task, especially when you are in unfamiliar territory.

    You have certainly provided me with some good information, and I feel a lot more comfortable making a decision now.

    I have to say that this forum is great!! I stumbled upon it while searching for Carrier info, and find it very informative. It is great to have a place where the members are so willing to be helpful.
