    New Carrier unit proposal

    Hey everybody,

    Recv'd 2 proposals (waiting on #3) for replacement of 5 ton heat pump unit. All 3 reps were impressed with ductwork design/integrity, no add'l work other than standard to connect return air to unit. Quotes for Trane and Carrier equip. I was leaning toward Trane, but one Trane rep didn't want to quote the XL14/15, said the 13 series was just as efficient in 2 stage for the same price(?). I am waiting on the other Trane rep who is going to quote the XL15, I'll be able to compare to this guy. The Carrier rep offered 2 systems, as follows:

    #1 Infinity
    HP- 25HNA660A003
    AH- FE4ANB006
    60000 11.10 15.30 57500 9.00 34200 (this is based on the A32 HP and +UI AH, see below for question regarding- ratings are same regardless)
    20kW staged heat strips
    2 stage recip compressor
    This would include the Infinity control system thermostat
    Includes 10C/10P/10L warranty

    #2 Performance
    HP-25HPA560A003
    AH- FV4BNB006
    59500 11.5 14 59000 8.3 36000 (again, HP is A32)
    20kW staged heat strips
    Standard single stage scroll compressor- variable blower
    Includes 10C/10P/5L warranty

    Difference in these systems is about 3%. Trane guy was about 50% more (NO KIDDING?) for an XL16 system. Sorry, I don't see it.

    Right now, I'm liking the Carrier Infinity system, which seems to be well respected. Here's my questions:

    1) Are these MLs good performers? If not, which would be better in this class?

    2) The performance proposal has slightly higher BTUs, as well as slightly higher EER. Significant, or no big deal?

    3) The ARI lists a +UI on the air handlers. What does the UI represent, should I ask for the UI version? As well, it lists the HP units as A3, A31, A32. What's the difference? I assume they are offering an active system, not a D/C'd setup?

    I appreciate everyone's input.

    1. Yes. The 25HNA6 is a good unit, but I still prefer the 25HNA9 heat pump because it has a scroll compressor which doesn't have to stop/start to switch stages. It's also a little more efficient. But, the 25HNA6 has a better low stage capacity at around 50%.

    2. Not really significant. The Infinity has a higher SEER and HSPF. Also, the Infinity will be more efficient in first stage.

    3. +UI means the Infinity user interface (i.e., the system uses the Infinity controller).

    Carrier two stage,5 ton that meets the federal $1500.00 tax credit are available now,not Infinity.

    Another 5 ton two stage is available in weeks that will use the Infinity controller,and also meets the $1500.00 tax credit criteria.

    If you pay federal taxes ,it would be a shame to miss out on $1500.00!

    All right!!! I heard that a 5-tonner eligible for credit was available/on the way, one from Carrier and from Trane. Dash, do you happen to have the MLs for the HP and AH for both of these setups? I would greatly appreciate it!

    Another great reason I come to this site!

    Dash, if these aren't the ones you had in mind, correct me:

    25HCB660 or 25HPA660, both with FV4CNB006T. 12.6 EER, 16 SEER, 9.5 HSPF.

    The 25HPA660 can be used with the Infinity control and fan coil (FE4ANB006T).
