The Chevy Chase Library reopened today after nearly a month because of a broken heating system.

The Montgomery County Public Library branch (8005 Connecticut Ave.) was closed on Dec. 10 to allow for county facility and maintenance workers to replace a deteriorated piping system that meant a non-functioning HVAC system.

THe Library, built in the 1960′s, did not have heat or cold air since the summer. MCPL and the county’s Department of General Services decided in November that Dec. 10 to Jan. 2 was the best time to close the branch.
