Im having a patio built and it was suggested by my hvac professional to move it so that I would have more accessible space on my small patio. Moving it would back it to my fence and require the lines to run along the outside of the house and along the fence line. The thought of having those lines exposed over that distance concerns me. Although the space would be of great value.
Does this seem reasonable? Any cons you see with this? My main concern is possible freezing of the copper line since so much of it will now be exposed to our Maryland winters. Anything else I should ask my guys about?
Thanks for your thoughts!
