What's different about smoke & co detector installation in New Haven
Battery-only smoke alarms should be sealed ten-year units. Renovations under permit typically require hardwired, interconnected alarms. A licensed electrician can plan locations under current code. Permits come from the city's building department. Test alarms monthly and replace them by the printed date.
Multi-family homes often have a separate small service for each unit, and knob-and-tube and cloth wiring are common. Heat-pump conversions, encouraged by state incentives, usually start with a service upgrade.
Weather and the utility in New Haven
New Haven faces nor'easters in winter and hurricanes and tropical storms in late summer and fall; Irene in 2011, Sandy in 2012 and Isaias in 2020 all caused long outages along the Connecticut shore. Low-lying areas near the harbor and Morris Cove are exposed to coastal flooding. Unlike much of Connecticut, New Haven is served by United Illuminating (UI), not Eversource, so meters, service drops and reconnection go through UI. Connecticut's Energize CT programs offer heat-pump incentives that change over time.
