Cooling load in Lisbon
Lisbon's older homes weren't built with cooling in mind, so central air is almost always an add-on — and on these tight downtown lots, that usually means a condenser tucked wherever it fits and ductwork pressed into service that was sized for heat, not cool air. Ductless mini-splits are a common fix here for the older homes and converted upstairs rooms that ducted central air can't reach without tearing into plaster.
