Trane XR11 (11 SEER) comes w/ yellow tag saying it's 10 SEER

folks at Trane saying to get 11 my inside coil and furnace have to be complimentary.
the inside coil is complimentary, but the furnace was my existing
Regardless.. purchasing decision was based on 11 SEER provided info.

There are many things that have to be in an optimal balanced relationship to get that extra SEER. An optimally balanced airflow through the proper evaporator coil and refrigerant control is extremely critical toward getting that extra SEER rating. If you didn't change the indoor coil and make certain the ductwork and airflow are optimal it would be pure luck if you get the extra SEER. Did the installer take "static pressures" and assure you the airflow was right for that condensing unit to get the 11 SEER Rating? Read as much as possible on the subject. -D

Thats correct.... That yellow tag, thats your federal tag that states what the SEER is on THAT unit, by itself... Theoretically, it could be a 12 SEER when matched to a larger indoor coil...and THATS how you get 11 SEER anyway. The indoor coil and blower assembly will be such that the outdoor unit is more efficient, and will be a 11 or better in most cases. Hell...Goodman makes it easy...you want a 12 SEER 3 ton unit? Easy..you get the 10 SEER 3 ton unit, and a 4 ton blower assembly and coil...bingo.

This is urtle.
If your not going to match up everything inside and out. Look on the yellow tag to get the seer rating and sometimes depending on the type inside system you have. You will get less than the yellow tag says. If your not changing the inside for get about seer rating as to getting what is stated.
