Verified record
Carlson HVAC is a Billerica outfit whose track record lives mostly in the permit book: BuildZoom counts 69 building permits filed since 2016, enough activity to place it in the top 18% of Massachusetts contractors on the platform's own scoring. Its Massachusetts HVAC license is active and state-verified, and BuildZoom separately lists a currently active Sheet Metal Business registration alongside an inactive Refrigeration Contractor license — the kind of trade-specific paperwork you'd expect from a mechanical and sheet-metal shop. There isn't much of a customer-review trail to go on yet. Google shows just two ratings averaging 3 stars, and BuildZoom reports it hasn't collected any reviews for the company at all — worth asking around or checking references before booking, since the permit history speaks to volume of work, not to how customers felt about it.
Typical Greater Boston range for this kind of work, from regional averages — not a quote from Carlson Hvac Inc. Use it to sanity-check bids, then get the real number in writing.
