    question for Trane heat pump and paired coil

    Hi, I have checked this forum to learn the HVAC related issues since I decided to replace my old system. Now I have a question to ask the experts here after my new heat pump and gas furnace were installed last week. So this is the first time I register and post a thread .

    My new hybrid system includes Trane units :
    Gas Furnace: XR95 single stage
    Heat Pump : XL15i 3.5 tons
    Coil unit : TXCC044BC3HCAA

    My question and concern is related to the heat pump and coil. I just found out that the manufacture date of the heat pump is 2011, but the coil was made in2007 which is definitely not a up to date model. (The gas furnace is made in 2011.) I called Trane to ask if it is OK to have the 2 models paired. The person I talked to did not give a precise answer but said it MIGHT have some changes on the coil in the 4-year period, better for me ask the dealer. I did call the dealer who did the installation, the sales person (comfort specialist) who handle my account said he will call the supplier to find out if there is any configuration change between the 2007 and 2011 coil models. If only the manufacture year is different, then it should be ok. For me, I have doubt about the new heat pump paired with coil that has been sitting somewher for 4 yeas. I am also afraid the sales person might pass me wrong info to avoid the reponsiblity of replacing the newer model. I would like to have professional advices from you guys about this matter before I make the final payment to the company.

    Should I insist the company to give me a 2011 model? Or is that truely ok to pair the 2011 heat pump with the 2007 coil?( I mean there is no problem related to system function in the days ahead.) How about the warranty? Will Trane honor the warranty if the 2 units are from different year? Will the 2007 coil make the warranty shorter? Any other isssues that I might not aware of?

    Any advice will be much appreciated.

    Just ask for the AHRI number for the matchup. If it has one, then you are good. If it doesn't, then you arent. Also, I would be curious where the heck that coil has been for the past 4 years...
    It's not rocket-science...

    I don't think the warranty would be effected, as it should start when you or your dealer registers it online after commissioning.

    Thanks for the reply.

    Frankly speaking, I cant' believe how could my dealer get a unit that is made 4 years ago. The sales person has not give me a call back yet. I wonder could it be possible the older model is cheaper so the company can make more money on my project. But that is just my guess.

    As for the AHRI, I did not get it from my installer or the sales person. I'll ask for it when the sales person come to do the final walk through and collect the payment. Can I go to the AHRI web site to get the AHRI number myself ? I tried once but dont' know the info required to be filled.

    As HVACtechNC and Dunkman both mentioned it should be OK but how can I find out if the coil unit has made any changes since there has been 4 years passed. Seeing something old installed with the new system just make me feel not comfortable. So do you guys think it's not necessary to have the coil changed to be the 2011 model?

    What is the model number of your furnace, I will need that to check for your AHRI ratings for you. I assume the model number of the Heat Pump is 4TWX5042A1000A.


    EDIT: I am showing that coil model # as a current Trane Coil model for a heat pump cased coil. I do not show any AHRI matchs for TDH1C085A9481A or a TUH1C100A9481A or TUH1C80A9601A(the XR95 furnace options for this heat pump) but that should not matter much because the XR95 is not going to meet any tax credit or rebate standards.

    In other words, I think everything is just fine, so go ahead and enjoy your system.

    The current model of that coil has a "4" prefix, so instead of TXCC044BC3 it would be 4TXCC044BC3, indicating it has a R410A TXV factory installed. I think the only thing the OP should confirm is that an R410A TXV was field installed, if it wasn't from the factory. I'm not sure what type of TXV the 2007 model of that coil came from the factory with, but it may have been an R22 TXV if it's before they started using the 2/4 prefix.

    Hi, Skyheating, my furnace model is TDH1C085A9481A, if you can find the AHRI number for me, that will be wonderful. I really don't know much about the system now installed in my house (AHRI type, Btuh, SEER, phase ....).
    The sales said he had done the load calculation for my house but he did not give those info yet. I noticed Trane has the instant rebate promotion but I'm not sure whether I will get it from my dealer. My great concern is if the old model will lower the HVAC performace or even void the warranty. If that is the case, then, to request a newer model will become necessary. When buying a product, I can take if I got the model from previous year, but not something from 4 years ago.

    How about Trane's product? Do you know any changes have been made in the last 4 years?

    Thank you beachtech. As I replied to skyheating, I have difficulty to fill those info.

    Hi Ryan, what doe you mean that "the only thing the OP should confirm is that an R410A TXV was field installed". (Sorry, I really new to the site. Who is OP? What is TXV?)

    I checked the sticker on the coil, it states refrigerent type is R410A only.

    OP = original poster (you)

    TXV = thermal expansion valve. It's a device that meters the refrigerant entering the coil. Trane started adding the 4 prefix to the coils (4TXC) to designate that they had R410A TXV's (conversely, 2TXC coils had R22 TXV's). If the coil says it's meant for R410A, you should be fine (it probably has an R410A TXV installed already).
