The best unit ever made

[tn a/c man]

What is the longest lasting unit you have ever seen.Here in east Tennessee we still have alot of 25-30+ year old york coffen style condensers that are running fine.

The one that is installed and maintained correctly, will be the longest lasting equipment.

have a lot of old ge and lennox units around here. oldest one i installed and recently replaced was a westinghouse from 1974. double cage cond fan motor was going bad and customer decided it was time to replace. old guy had really taken care of it and it looked like new inside.

It has more to do with the proper application, installation and regular service than it does with the brand.

Here's my oldest. Took 2 of these out in the same summer. This one worked fine. The other one had a bad contactor. It sat outside.
