as long as they were never in direct sunlight or in hot weather, they should be ok.
just to be sure, have one developed and see.
it's best always to keep unopened film boxes in the fridge, and when a film has been exposed and can't be developed right away, it should be put in it's little airtight plastic box when the air humidity index is about 30%, and not more, and freeze it until the day you have them developed.
film development has been standardized for ages, and all the development machines are completely automatic, so there's very little to worry about this. Telling the lab they're very old negs will not change a thing.
where there is lots of variations is in the printing of those negs. some labs do very good work and others stink.
