Ductless Mini-Split Installation in Rockville, MD
Older homes in Rockville often have rooms the original system never reached well: sunrooms, third floors, converted porches. A ductless mini-split conditions those spaces directly. 24-7 HVAC of Bethesda serves Rockville, Twinbrook and King Farm. Our phones are answered around the clock, every day of the year.
Rockville housing and systems
Homes in Rockville are mostly 1950s ramblers in Twinbrook, townhouses in King Farm and Fallsgrove, and condos along Rockville Pike. Twinbrook ramblers usually have compact basement or closet systems with older ductwork, while the newer King Farm and Fallsgrove townhouses mostly have heat pumps with attic air handlers. Knowing the housing in Rockville helps our technicians plan each ductless mini-split installation call before they arrive, including which parts and tools to bring.
