Common Boston HVAC emergencies

Furnace not igniting or blowing cold
Furnace won't ignite · blowing cold air · short-cycling · burning smell on first startup. In Boston, a furnace failure in deep winter can lead to frozen pipes within hours. If you smell gas, leave the building immediately and call 911 first.
Pipes freezing while heat is out
Once Boston indoor temps drop below 55°F, pipes in exterior walls and unheated basements are at risk. If your heat is out and the forecast is below freezing, this is an emergency — restoring heat fast prevents thousands in burst-pipe damage.
AC out during a summer heat wave
Outdoor unit silent · warm air at vents · short-cycling. Even short Boston summers bring stretches of 90°F+ days — an AC failure during a heat wave is a real-comfort emergency. Most causes are electrical and require a technician.

Boston's cold-winter climate & your HVAC
This is a heating-dominated Zone 5A (Cool-Humid) climate — the furnace is the most-used appliance in the home for 5–7 months a year. Federal SEER2 13.4 (North Region) minimum applies to new AC equipment, and AFUE 90+ is the de-facto baseline for new gas furnaces in cold-winter regions.

HVAC in Boston, MA: local data & sources
Every numerical claim below references a federal, state, or municipal primary source — NOAA climate normals, U.S. Census ACS, the Massachusetts licensing authority, and your local utility's published rebate program.
NOAA NCEI 1991–2020 Normals
Boston Logan International Airport (KBOS) is the NOAA reference station for the city. Per the NOAA NCEI U.S. Climate Normals 1991–2020 (station USW00014739), Boston records an annual mean temperature of 51.9°F, approximately 5,545.4 annual heating degree days against only 801.8 cooling degree days, 43.59 inches of annual precipitation, and 49.2 inches of annual snowfall. The 6.9:1 HDD-to-CDD ratio plus coastal humidity and nor’easter snow-load exposure defines Boston as a classic Zone 5A cool-humid climate — winter heating capacity is the dominant HVAC design factor, and older-home weatherization often matters more than equipment selection.
U.S. Census ACS 2022 5-Year
The U.S. Census Bureau ACS 2023 5-year estimates (Tables B25040 and B25035 for Boston city, Massachusetts) report 279,216 occupied housing units with a median year built of 1947 — among the oldest housing stocks of any major U.S. city, reflecting Boston’s dense triple-decker, brownstone, and pre-war row-house inventory. Heating-fuel distribution: 57.2% utility natural gas (159,684 units), 30.7% electricity (85,739 units), and a remarkable 7.2% fuel oil / kerosene (19,969 units). The fuel-oil share is an order of magnitude higher than most U.S. cities — a New England legacy — and represents one of the clearest statewide decarbonization opportunities, which is why Mass Save heat-pump incentives are among the most generous in the country.
Massachusetts Licensing Authority
Massachusetts does not issue a single statewide HVAC-specific contractor license the way some states do. Instead, HVAC work in Boston is regulated through several overlapping credentials: refrigerant handling requires federal EPA Section 608 certification; gas-fitting and plumbing portions of HVAC work require licensure through the Massachusetts Board of State Examiners of Plumbers and Gas Fitters; sheet metal work is licensed separately. Verifying that a contractor holds all required credentials before authorizing work is the baseline due-diligence step for every Boston homeowner. Permit fees for residential mechanical work are set by the City of Boston Inspectional Services Department (ISD); contact ISD directly for the current fee schedule. For current utility rebate dollar amounts, visit masssave.com (the joint utility rebate program that includes Eversource and administers some of the most generous heat-pump incentives in the country) or use the ENERGY STAR Rebate Finder with a Boston ZIP. The federal Section 25C tax credit was terminated for installations after Dec 31, 2025 (OBBBA, P.L. 119-21) — the local incentives above remain active for 2026.
Eversource, DSIRE, City of Boston Inspectional Services Department (ISD)
Boston homeowners served by Eversource may qualify for savings through Mass Save Heat Pump Rebates (up to $10,000) when installing qualifying high-efficiency equipment. State HEAR rebates and utility programs remain the active federal-funded path in 2026 — the federal Section 25C tax credit was terminated for installations placed in service after Dec 31, 2025 (P.L. 119-21). Primary source: DSIRE — Massachusetts.
The federal Section 25C Energy Efficient Home Improvement Credit was terminated for installations placed in service after Dec 31, 2025 by the One Big Beautiful Bill Act (Public Law 119-21). State HEAR rebates and utility programs remain in effect. See our HVAC financing options for what's still available.
