I have an 84 model doublewide on one of my places.It was put there new.We've been patching on the original A/C for about the last 5 years.It's completely out with no chance of repair this time.$7700 for a new system.Thinking about getting one big window unit for the living room with heat and air combined and then do just A/C units in bedrooms.Probably spend $3k on them because we would install with a wooden box in each window with insulation instead of just letting them sit on the window sills.I could probably swing the central heat and air,but it's gonna hurt.
Any advice?
