I paid for an upgrade (from 13 seer to 16) and the installer upgraded the wrong unit. When pulling the 16 and installing the 13, the installer said that he needs to pull the TXV. Is there any harm in leaving it?
Wrong unit is XC16, swapping for 13ACD - each 3 tons. It's my downstairs unit and they offered to let me keep their "mistake" for $1k, would you pay that?
