What winter actually asks of a system in Andover
Andover drops below freezing on about 123 nights a year, and below 10°F on about 14 of them. Those coldest nights — not the average winter day — are what a furnace, boiler or heat pump has to be sized for. A system that keeps up in November and struggles in January is usually a sizing problem, not a broken one.

Andover's natural gas is distributed by Eversource Gas of Massachusetts. The town sits inside the area affected by the September 13, 2018 Merrimack Valley overpressurization, which the NTSB traced to a low-pressure distribution system originally installed in the early 1900s with cast iron mains and operated at roughly half a pound of pressure — the same pressure delivered straight to household appliances. The event damaged 131 structures and shut the low-pressure system down for 8,447 customers across Lawrence, Andover and North Andover. Since July 1, 2026 the town has also been operating under the Specialized Energy Code for new construction, on top of a Stretch Code it adopted voluntarily back in 2011.

The low-pressure natural gas distribution system in the Merrimack Valley was installed in the early 1900s with cast iron mains and used 14 regulator stations to supply and control pressure, delivering gas to mains at about 0.5 psig — essentially the same pressure supplied to the customer's piping and used by appliances. The system was confirmed shut down for 8,447 customers in the Lawrence, Andover and North Andover areas, with an additional 2,447 customers outside the area shut off as a precaution.
Natural gas in Andover is distributed by Eversource Gas of Massachusetts, which files applications with the Andover Select Board for gas work on town streets, and Massachusetts DPU public hearing notices for Eversource Gas Company are posted through the town's agenda center.
Andover adopted the Stretch Energy Code effective January 1, 2011 and voted at the April 2025 Town Meeting to adopt the DOER municipal Opt-in Specialized Code effective July 1, 2026. The Specialized Code applies only to new construction; additions, renovations and historic buildings follow the existing Stretch Code. It does not ban fossil fuels and mixed-fuel pathways remain available.
The town advises residents that wind can cause snow to drift in ways that cover home heating or drying vents, and to monitor those vents and ensure they are clear and not blocked by snow.
