Bethesda housing and systems
Homes in Bethesda are mostly 1930s through 60s brick colonials and Tudors, newer custom homes built on older lots, and condos near downtown Bethesda. Older Bethesda colonials often have the furnace in the basement and a second system in the attic for the upstairs, so we check both whenever one floor is uncomfortable. Knowing the housing in Bethesda helps our technicians plan each ac replacement & installation call before they arrive, including which parts and tools to bring.
