Old radiators in the south, forced air in the north
The southern end of town around Spring Glen, Whitneyville and Westwoods holds many homes built between the 1910s and the 1950s, with hot-water boilers, some steam, and radiators that are often original. Farther north, Hamden Plains and Mount Carmel move into postwar capes, raised ranches and newer colonials, mostly on forced air. Gas reaches much of town, but a good share of homes still heat with oil, so burner tune-ups and questions about switching come up on almost every visit.
Hamden also has a lot of rental housing near Quinnipiac and the New Haven line, where landlords need repairs that are quick and documented. We leave a written summary with every visit so owners and tenants see the same information.
