We spoke about your units. We can move those for you...
My plans are to make the deck 16' X 16" with a picnic shelter style roof. Walk out the back door and you are under roof.
We did discuss. May just wait until the ac units need replaced and then move them. Last time I had one of those annual ac tuneups/inspections, they tried to convince me I needed a whole new system and that failure was imminent. Have never had issues.
