Furnace not igniting or blowing cold
Furnace won't ignite · blowing cold air · short-cycling · burning smell on first startup. In Boston cold snaps, call right away if freezing weather is forecast — a home without heat risks frozen pipes. If you smell gas, leave the building right away without flipping switches or using phones inside, then call 911 or your gas utility’s emergency line from outside.
Pipes freezing while heat is out
If you will be away during cold weather, the American Red Cross advises leaving the heat on and set no lower than 55°F (Red Cross). If your Boston home’s heat has failed and freezing weather is forecast, call for service right away.
AC out during a summer heat wave
Outdoor unit silent · warm air at vents · short-cycling. An AC failure in Boston summer heat is worth a same-day call. Electrical and refrigerant faults need a technician to diagnose.

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 2023 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. 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).
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 efficiency program that includes Eversource) 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).
Eversource, DSIRE, City of Boston Inspectional Services Department (ISD)
Boston homeowners served by Eversource may qualify for savings through Mass Save Heat Pump Rebates when installing qualifying high-efficiency equipment.

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).
