Carrier coil leakage problems

[Unclev]

Hello all,
I am going to be replacing my old heat pump with either a Carrier or American Standard. I am concerned about the Carrier system since a few people locally I know had leaking indoor and outdoor coils after about 3 / 4 years. I have also read about these issues online. Has Carrier rectified this issue or have you still been seeing it with the latest models. Thanks again to all that reply. I appreciate your professional info!

My friend used to work for Carrier and said the reason their coils leaked alot is because they had them made in mexico, and they mixed other metals in with the copper. Not that other companies haven't done the same thing. But if it were me, i'd go with an American Standard, not that my opinion matters but I just condemned a carrier coil today with a bad leak. American Standard and Trane are what my company sells, and they are very reliable, but are prone to the same problems as every other unit.

Carrier seems to have gotten the leaking evaporator coils and condenser coils down to a reasonable minimum of late. Our local tech rep said that, with the move to aluminum evap coils, the production is moving back to the states. We are primarily a Carrier dealer and my 4 year old system is doing just fine, but I'd say that Trane/American Standard has the aluminum coil thing down pat. I'd probably stick with the American Standard.

Either unit is fine get the 10yr part and labor warranty on what ever you buy

Thanks to all that responded. When did Carrier went to an all Aluminum evap. coil. I'm torn between the Carrier with a Copeland scroll single stage BUT does not true demand defrost ( I live in PA). On the other side the American Standard does have true demand defrost but I'm leery about the recip. compressor that they use. Also who can I contact to verify the Carrier air handler I was quoted does have an all Alum. evap. coil. Any thoughts?
Thanks again for all your professional input.

Doesn't really matter too much about the recip.. There is a reason why trane (american standard) still manufactures their own compressors, unlike carrier, and other companies who use copelands, and maybe other brands of comps. Trane (another name for american standard) has engineers that design those compressors ESPECIALLY for their units. They are called CLIMATUFF I believe.
