Just over 2 years ago we bought a house with a dated A/C package unit.
14 months ago we replaced the A/C with a 3 ton Trane package. After
about 9 months of improved cooling over the old unit, we began to
experience problems with cooling, pipe leading from the condenser to
the coil froze, etc.

Dont understand why it could be working for 14 months fine, then a
return air duct mysteriously becomes sealed? You would have gone
thru a heating season in that time, how on earth did the heat work
during this time since it shares the same ducts?

I agree, seems strange that it worked now it has failed.

Your contract/agreement will be the guide on what liability the installer
has. If you failed to ask for an evaluation of the ducts it will be on you
nickel. If you asked for an evaluation and they failed to do one it is his
nickel. Most swaps are checked at operation and then if they work all is
well. Yours worked for a long time and now there is a problem.... Na
Something else changed you just not aware of it.
Being an informed consumer is an full time job.

Sounds more like the return duct work has collapsed. You been in the attic?

My brother and I had extra insulation blown into our homes this spring. Same
installer, same day. My a/c worked fine and my brothers return duct had
been collapsed by the installer. (different models of the same builder). The
insulation installer paid $140 bucks for the duct repair.
