My new Trane will be a year old next month and is running fine. I did
not take the extended warranty which would have required me to have
the dealer come out once a year and check fluid levels. My question
is: Is it necessary to do this? I mean, if the a/c stops cooling I
know to call them ... but can lack of a certain level of freon or
whatever the new ones use now, cause damage? I want to take care of
it but not waste money. Thanks.

I guess I will side with HeyBub rather than with Bubba.

A/Cs either work or they don't; not much preventive maintenance; except
keeping the fins clean.
Furnaces are another story. They do need to be cleaned.
