A/C missmatching parts
 
The contractor quoted a Bryant 3 ton furnace, condenser, and an evaporator Coil ADP (advance distributor product) brand. I was wondering why he didn't use all Bryant products.

Thanks for your responses.

A-Coil's will always be made through some other party. Only thing Bryant is doing is slapping their nameplate on someone else parts. My A-Coil is made by some other company, but both my inside unit which is a Lennox Signature series, and my outside unit, which is Armstrong air are from the same company, I go to sleep at night, knowing that the guy that did mine is standing behind the install.

don't know if Bryant makes there own coils or buys them and has there name put on them. Really only thing important is the system is a matched system. Ask the contractor for a AHRI certificate. This is also avalible online and you can research yourself. The certificate will show they are matched, been tested together, and show the actual goverment SEER,EER & HSPF ratings. I give these cerificates to most of my customers especially if they are considering putting in new equipment in the name of energy savings

How did you come to this conclusion? Just curious ... I know that Trane makes their own coils. They recently had troubles keeping up with demand on some of their coil models, and in discussions with my Trane rep about that we got into the topic of where these are made, and by whom. Trane has several locations around the country that make coils for their own products (one of them not too far from here) so I was just curious how you came to the conclusion that all A-Coils are made through some other party.

Indoor coils that are third party, have never been tested with the condenser they are suppose to match up with. Only a computer simulation was done. OEM evap coils are psychically tested, an proven to meet the listed rating of the claimed match.

There are some combinations of 3rd party coils + condenser that are ARI certified (for example ADP + Trane 4TTR condensers).

ARI certification requires payment by one or both parties, so many manufacturers choose not to certify their equipment with 3rd party coils. That doesn't mean it won't work, of course, and in many cases the manufacturer will "self-certify" the combination (which means they'll provide you with troubleshooting support, and they guarantee that the combination will work).

Third party coils are only computer simulation tested. And just 1 or 2 years ago AHRI changed the cert requirements/simulation method, sine many third party companies were claims high SEER, but were off by more then 10% when it was actually tested.



If an OEM were to certify the match, they would have to physically test it. OEMs are not allowed to just use a computer simulation. And must be within 5% of claimed rating to be AHRI listed.

My point is that some manufacturers will match their equipment with 3rd party coils sold through their various branches, and will "certify" that the combination will work properly, and will provide with troubleshooting assistance if you choose to install those combos. I did not intend to convey that any self-certified EER/SEER ratings should be considered accurate, of course.

In this particlar case all Bryant combinations including ones with adp coil have AHRI certificate. I know I am a Bryant Dealer. If this if a Match there is already an AHRI cert all the OP would have to do is ask. The Contractor may not be aware of the certificate but his distributor would have the reference number which then a certificate could be found on the AHRI web site.

If it is not a matched system with an AHRI certificate why put it in. I won't cost any more than a system with one. You are buying all new equipment and might as well Know the true preformance. AHRI will also show actual BTU's wich are not always rated btu's.

Most of the time that a brand distributor sells a third party coil to match to the brand. The third party coil maker has an agreement with that manufacturer. And often makes a branded coil for that manufacturer.


When Unico was about to be put out of business by the DOE. Lennox went to bat for them.
