R410 system stolen lineset
I recently bought a house on foreclosure. The air conditioner line set was stolen before we purchased the home and it has sat for over a year. One contractor gave me a price to replace the lineset, but another contractor told me that since the R410 unit has been exposed to the air it could have moisture in it and that I need to replace the whole unit. He said that if I have the lineset repaired the unit may work, but it will cause damage to the unit and it won't last very long. Wanted some advice on which one to believe.
Thanks!
