Somerville at a glance
Heating and cooling climate
NOAA's 1991–2020 climate normals for the BOSTON LOGAN INTL AP, MA station (about 5 miles away) show about 5,545 heating degree days and 802 cooling degree days in a typical year, with about 92 nights at or below freezing and 14 days reaching 90°F or more. Heating demand is far larger than cooling demand here, so the furnace, boiler or heat pump carries most of the load and a breakdown in a cold snap is the most pressing kind of call.
How homes in Somerville are heated
According to the Census Bureau's American Community Survey, 70% of occupied homes in Somerville heat mainly with utility gas, 19% with electricity, 6% with fuel oil or kerosene and 3% with propane (bottled or tank gas). Gas-fired furnaces and boilers are the most common setup, which means igniters, flame sensors, gas valves and venting come up often on heating calls.
Housing age and HVAC systems
The median year built for housing in Somerville is 1938, and about 80% of its 37,756 housing units were built before 1980. Many older homes here were built around hot-water or steam boilers and radiators, and some have had forced-air systems and central air added later, which can mean older ductwork and mixed equipment.
