replace AC outside unit -- HELP!
Hi,
We just replaced our coil (American Standard 3 ton, model number: 2TXCB036AC3HCAA) because it leaks freon. A month later, the compressor won't start and the technician said we need a new condensor(he did tried the hard start). They quoted a Rheem (3 ton 13 sheer) for us. He also said it's high efficient.
Since we can't replace the new coil again, my question is, if the coil is not energy efficient (which I'm not sure), with this energy efficient condensor, do we still reach the purpose of "efficient AC"?
What kind of match of the inside and outside units we should look for?
Is $2000 a reasonable price for a Rheem 3 ton condensor?
Another question, is "American Standard" a Trane?
Thank you very much for any help!

If your indoor coil is 13 seer keep it! If it is not get a New indoor and outdoor (complete) system.

We would want to know if that new coil is a unit designed for 13 SEER, and if so, what did they do to match it to your old 10 SEER condensing unit. ( Change piston? TXV?) And do they now know what they have to change back to match it back up to a new 13 SEER unit?
As far as efficiency, a coil per se does not have a SEER rating. It is the condensor, and the proper match to coil surface area, which gives an overall system efficiency. If you put a new 13 SEER condensing unit on an old coil, you can make it work with the proper piston or TXV, but the system will not be 13. The manufacturers have done matching calculations and can tell you what you system SEER would be.

How can I find out whether it's designed for 13 seer? I sent a message to ask the question on Trane's web site. I do know the coil has a build in TXV.
Also, I plan to use a different contractor than the one who installed the coil (because unhappy experience). So I don't want spend money to replace the one month old coil. That's why I'm look something matches it.
Thanks!

Are you unhappy with the original contractor because the condensing unit failed? Or, for other reasons?
If it's because of other reasons, that's fine. But the failure of the old condensing unit is likely not his fault.
You can leave the existing coil and replace the condensing unit. It should work fine if installed properly. The question remains as to what eer you will get. That cannot be answered easily. But, more than likely it will be above the eer of the old condenser and likely somewhat below the new condensing unit if the coil is not matched. This question is probably best left to your tech.
