Why Sudbury homeowners plan insulation and heat pumps together
A heat pump sized for a leaky house is bigger and more expensive than it needs to be. By sealing and insulating first, Sudbury homeowners can often choose a smaller system that runs more efficiently.
Older homes with radiators or baseboard heat often switch to ductless heat pumps, which avoid opening walls for new ductwork.
Being close to Westborough means our crews know Sudbury well and can schedule quickly.

Know your Sudbury home
Sudbury is mostly larger single-family homes, many colonials and contemporaries built from the 1950s through the 1990s, plus historic homes near Sudbury Center.
Sudbury is a largely residential town along the Sudbury River, with historic homes around Sudbury Center and many larger colonials and contemporaries built from the 1950s on. Big homes with cathedral ceilings, skylights and finished attics often have hidden air leaks we find with blower door testing.
From the inner suburbs to MetroWest, Middlesex County homes range from 19th-century two-families to large newer colonials, each with different weak spots.

Insulation targets and incentives in Sudbury

Climate & code
Climate zone 5A targets
In climate zone 5A, which includes Sudbury, recommended attic levels are R-49 to R-60, well above what most homes built before the 1980s were given. Many Massachusetts towns have adopted the Stretch Energy Code or the Specialized Opt-in Code, which raise insulation and air-sealing requirements for new construction and major renovations.
