home a/c help

I have a 10yr old trane a/c unit..was told when I moved in the a/c hadn't been ran in approximately 4 yrs, a/c needed charged. Lasted 1 summer & got ice build up on the side of the furnace where a/c lines come in. Following yr, same thing. I've been told this r-22 cost roughly 80.00 a pound...should Iscrapthis unit or is there something I can do to possibly fix this? Iknow nothing about a/c's any insight would be appreciated & helpful

You can put some soap and water in a spray bottle and search for a leak.
If you are lucky, it can be a leaking valve core outside at the service ports.

A more likely location is the evaporator coil...



You would still need to pay someone to repair the leak or replace the evaporator coil, but finding the leak can save you some money.

Trane units can also leak at the rotolock connection at the compressor outside.

I will look into the evaporator coil. I was told that cleaning the "A" coil may fix the problem...any truth to that?

Cleaning the coil will NOT fix the problem.

There are environmentally clean R-22 substitutes available now that are compatible with the system oil, I don't know how their price per lb., compares; ask about them; $80 a lb., is too much to spend.

Inquire about them...
Find & fix the leak!

Either find and fix the leak or replace with new. 10 years is somewhat old for a system, but it more so depends on how much a true repair will cost.
