I have a 15 year old York unit.
Last summer I had a tech add about 2.5 lbs of freon. He didn't do any leak testing. Last week, a tech from the same company added 5 lbs of freon. He also did an electronic leak test and said that the evaporator coil was leaking and that it should be replaced. I guess the only concern I have is that he didn't attempt to pinpoint the exact leak, since the coil itself is not easily accessible. Should he have pinpointed the leak to determine if it was repairable? Or at least looked at the coil??? He didn't even do that. Of course 5 lbs of freon is alot and the thing was iced up before he came, so I guess there's a good chance the coil is shot.
He quoted about $1700 to replace the coil. I assume this is the cost to replace the entire indoor unit, since he said he can't find a matching York coil. Is this reasonable? Shouldn't he just be able to replace the coil with a York coil? Instead of the whole indoor unit?
If the indoor unit does need to be replaced, should I replace the outdoor unit as well?
Thank you, RAJ
