Lake Ronkonkoma takes its name from the legendary lake it surrounds — the largest freshwater lake on Long Island at 243 acres.

Long Island winters bring freezing temperatures, coastal winds, and occasional ice storms that push heating systems to their limits. For Lake Ronkonkoma homeowners, a reliable furnace is essential from November through March, and Long Island Climate is the trusted local heating expert serving Lake Ronkonkoma and all of Suffolk County.
