The area's colonials, split-levels, and townhomes are at the age where furnaces, heat pumps, air conditioners, and water heaters need experienced attention, and many older panels are due for upgrades. Humid Chesapeake-region summers add strain, winter cold snaps test heating systems, and finished basements make sump pumps and moisture control priorities.
