Andover, MA Contractors: HVAC, Roofing, Plumbing & More

Andover sits in southern Essex County with about 36,000 residents and a housing stock that leans large, established, and well-maintained — anchored by Phillips Academy in the town center, with neighborhoods spreading out through Shawsheen Village, Ballardvale, and West Andover. The mix runs from 19th-century homes around the academy and along Main Street to mid-century estates in West Andover to newer subdivisions on multi-acre lots.

Median construction is around 1965, but Andover has more pre-1900 housing than most Essex County suburbs and a higher share of homes over 4,000 square feet. Most retrofits involve multi-zone systems on larger floor plans, mini-split additions on older homes that lack ductwork, and ducted heat pump replacements on newer subdivision stock.

Andover is in National Grid electric territory, which makes homeowners eligible for the full Mass Save rebate program. Whole-home heat pump retrofits have qualified for up to $8,500 ($2,650 per ton) in recent rebate cycles paired with the required free Home Energy Assessment. Partial heat pump and ductless mini-split systems typically qualify for $2,500–$6,000. The Mass Save 0% HEAT Loan adds up to $25,000 of 7-year financing — particularly relevant in Andover where larger homes often need multi-zone retrofits exceeding $30,000. The free Home Energy Assessment is the gating step and on Andover's older estate homes typically surfaces meaningful insulation work subsidized at 75% or higher. Phillips Academy area homes have been heavy adopters of partial-electrification strategies that preserve historic radiator systems while adding mini-splits for cooling.

Andover requires a building permit for any HVAC system replacement, with the Building Department at the Town Offices on Bartlet Street handling review. A separate electrical permit covers heat pump circuits, and National Grid coordinates the meter inspection on panel upgrades. Standard permit turnaround is generally a few business days. The Andover Center Historic District around Phillips Academy and the downtown common requires Historical Commission review for any exterior change visible from a public way — including outdoor heat pump condensers. Ballardvale also has a designated historic district. Side or rear placement out of public view usually clears review without a hearing. Most established local contractors handle the filings as part of the project.
