moving a condensing unit to other part of yard
hello the lady is getting a sliding door installed and condensing unit is in the way. the easiest way to run part of the extended line set necessitates about a 12 foot run along the roof. otherwise I have to drill 2 holes to get through the garage. the line set will be about 25 to 30 feet longer. will running it 12 feet across the roof cause problems?
