Trane or American Standard. If they sell you anything else ask to see, in writing, the ARI reference match #. All of the matched coils will be tested and referenced by the Air Conditioning and Refrigeration Institute. They are given ratings of efficiency with the outdoor unit matching the indoor coil.
There is a reason why coils are matched. Yes, it may work, but it may not work as designed.
Your contractor should be capable of matching the coil properly. There are different sizes and dimensions etc, that I would not know without actually seeing the application. As long as the coil fits the ducting, is the proper capacity, and a match for the outdoor unit (i.e. Trane), you should be ok.

 

That, and make sure the warranty on the indoor coil will be the same as a trane coil.

That must be a tight spot for the coil, if their going with 3rd party.

 

Thanks for the responses. I played around on the AHRI site and did an AC search in an effort to find matching coil model numbers but it keeps coming back with zero results. I guess I'm leaving too many lines blank/unchanged for it to kick out matches.

The furnace will be in the attic and the location does have to be moved from the current location BUT there will be plenty of room for the coil in the new location. Don't know why they would go third party unless it's it's to save money....?

Any help with a matching Trane coil model number would be greatly appreciated. I want to have as much info as possible when I call tomorrow.

Thanks!

Thanks, much appreciated.

 

Had the install last week and you won't believe what the Trane Comfort Specialist did. They installed the wrong furnace! Unlike what I wrote in post #1 the contracted furnace was to be the TUH1D100A9601 (100k btu). They installed the TUH1D120A9601A (120k btu) furnace. It's no wonder this flame thrower heats the house so fast! They're not going to be very happy when they get a call from me requesting the correct furnace tomorrow morning. Not looking forward to this one...

 

Trane uses 3rd party coils to meet the standards required for the tax rebates. They were using aspen coils but are working on getting their own to meet gov. standards for the rebates.

as for the furnace being oversized..did they size it for a 100k and put in the wrong one? Or did it size out to a 120 and they just charged you for a 100?

 

A matching Trane coil was installed 4TXCD061. I wonder if the coil that works with the 100k furnace they should have installed? No, 100k is still oversized (shocker) but we needed the 5 ton blower for the 5 ton XR13 condenser. I don't want the 120k furnace. It's like a flame thrower. Just hoping the installer cooperates on the removal and replacement with the proper size.

 

Did the contractor do a heat loss/gain calculation ?

 

No. None of the three Trane or Rheem contractors did a load calc. I regret not having time (12/31 tax credit deadline) to demand this.

 

if 100k is oversized then 120K is deffinately oversized, especially with a single stage furnace.
If you agreed on a 100 and have it in writing I see no reason why they wouldn't have to change it out.

 

Written clear as day on the contract and on the city permit.

 

The TDH1D110A you posted in your first post has the SAME nominal btu output as the TUH1D120A that you said they put in......exactly 104,500 btu.


The TDH is a downflow/horizontal, the TUH is a upflow/horizontal. That may be the reason they put in the TUH.

BTW....why did they not put in a heatpump??? You live up north??

 

No heat pump because of ridiculous CA electric rates. The contract was for the TUH1D100 (92,150 nominal) and they installed the 120 which is 104,500 nominal. The furnace is in the attic. They screwed up and installed the wrong furnace.

 

Your original post listed a TDH1D110A9601A...you posted it. I didn't.

That doesn't mean that they listed theTUH1D100 on the final proposal.

Get your facts straight before you make an a$$ out of yourself.

 

Superd77- please reread my post #7. If you do you will see that I wrote that the contracted furnace was for the TUH1D100 which changed between my original post and the the contract signing.

I appreciate your comments but I don't think I'm the one being the a$$ here.

 

The 4TXCD061 coil is the same width as the 100k furnace (TUH1D100A9601), so should not be a problem.

Let us know what the dealer says about the wrong furnace being installed. They didn't have to oversize it to meet tax credit requirements, because the furnace is already 95% efficient.

 

Let us know what the dealer says about the wrong furnace being installed.

My dealer is having the supplier order the TUH1D100. This was a supplier error. The supplier shipped the 120 because it had no 100s in inventory and decided not to mention it because it was assumed this would be an "upgrade." My Trane dealer also admits they should have caught it. Correct furnace will be installed once it arrives from the supplier.

Again, thanks for the help.

 

glad to hear they're willing to admidt they should have caught it.

Unfortunetly, it is something that happens. I've put in a wrong size furnace before. Caught it when I was setting the blower speeds.

 

First question is why is trane selecting the coil and not the dealer that sold it to you?

 

because not everyone in the supply chain is smart.

Dealer orders equitment. Order taker at supply house punches in numbers. Guys in warehouse pick the equitment according to the numbers. Supply house delivery driver picks up equitment, and unloads at dealers shop. Guys in dealers shop organize job. Installers load equitment.

The people in bold normally don't have alot of equitment knowledge. Just number matchers.
