Hi everyone. I currently have a Bryant 2.5 Ton Heat Pump system that was installed back in 1995. I'm currently getting quotes for a new system and the Trane Dealer noticed that I currently have a 5/8 inch copper line and the Trane specs call for 3/4" line.
What I wanted to know if does Lennox, Bryant, or anyone else use 5/8" line? I'm getting some other quotes and pulling new lines is going to be difficult based on the location of the indoor unit.
