Cambridge packs dense, old housing between the Charles River and the Somerville line, and its HVAC runs on century-old bones: triple-deckers, Greek revivals, and Victorians heated by aging boilers — many with radiators and no ductwork — through long winters. Summer brings the other peak: garden-level and top-floor units that never cool down, and a high water table near the Charles that keeps basement equipment rooms damp year-round.
No-heat calls dominate winter: aging boilers and furnaces in century-old buildings fail on the coldest nights, and steam systems need specialists who still understand them. Summer brings the other peak — upper floors of triple-deckers and brownstones that never cool down, and condensers straining through heat waves.
The housing is historic and tight — triple-deckers, Greek revivals, and Victorians from the 1800s, many converted to multi-unit rentals with heating systems from several eras patched together. High water table near the Charles keeps basement boilers and air handlers damp; old brick and stone foundations wick moisture continuously. Balloon framing hides retrofit ductwork that was never sealed, and the housing stock's density means one building's failed boiler is the whole block's emergency.
When heating or cooling trouble hits your Cambridge home — a boiler that fails in January or a top-floor rental that bakes every summer — AirFlow HVAC connects you with an independent local HVAC pro. Tell us what is happening and we will match you with a pro nearby, fast.

Homes here, and the HVAC problems they get
Local housing notes
- Triple-deckers, Greek revivals, and Victorians (1800s), many converted to rentals with aging boilers.
- High water table near the Charles River keeps basement equipment rooms chronically damp.
- Radiator-heated buildings with no ductwork — ductless mini-splits are the standard cooling retrofit.
- Chimney-liner decay: old coal-era chimneys now carry furnace and boiler flues, and crumbling liners leak carbon monoxide into living spaces.
- Rear-alley condensers: tight lots push cooling equipment into shared alleys where airflow is poor and access is worse.
Common local HVAC issues
- No-heat emergencies: aging boilers in converted multis fail on the coldest nights.
- Upper-floor overheating: dense old housing without central AC bakes every summer.
- Damp equipment rooms: high water table corrodes below-grade boilers and air handlers.
- Nor'easter freeze-ups: coastal storms dump wet snow across the dense grid, and top-floor tenants report mini-splits icing over while ground-floor radiators bang and knock.
- Skylight heat loss: converted top-floor units with old skylights bleed heat all winter and bake all summer.
