Massachusetts Pro HVAC LLC

Massachusetts requires a permit for any HVAC system replacement, and Shrewsbury's building department handles the review. A heat pump retrofit also needs a separate electrical permit for the new dedicated condenser circuits, which a licensed electrician pulls. Because Shrewsbury Electric & Cable owns the local distribution system, any electrical service upgrade — common when an older home's panel can't support a heat pump load — is coordinated directly with SELCO rather than an investor-owned utility. Reputable installers handle both permits and the SELCO coordination as part of the job.

Shrewsbury project costs tend to run slightly below the Boston metro because of Worcester County labor rates. A full whole-home heat pump retrofit typically lands in the $18,000–$28,000 range before any rebates; a single-zone ductless mini-split usually runs $4,500–$8,000 installed; and a like-for-like gas or oil boiler replacement is generally $7,500–$13,000. Newer subdivision homes with usable existing ductwork sit at the lower end of the retrofit range, while older lakeside houses that need new line sets or electrical upgrades push higher.

Massachusetts requires a written contract and a Home Improvement Contractor registration for most residential hvac work; ask for the registration number and check it before paying a deposit.
