Problem: No central Heat and Air and no place to install one. A concern for breaking the asbestos siding and whether we could do the job without too much construction. Also, we had to find a place to put the outside unit as there was no ground space available.
Solution: We installed a 19 SEER 5 zone Mitsubishi ductless mini-split covering three zones downstairs and two upstairs. We hung the unit on factory brackets to provide a place for the unit outside. Pulled a permit for the job.
