Dan's Service

A BuildZoom score of 103 puts Dan's Service in the top 10% of Massachusetts's roughly 139,000 licensed contractors — a solid credential for a small, family-run mechanical shop. Based in Medford, the company says it's been installing, repairing, and servicing air conditioning, heating, refrigeration, and ice-machine equipment for commercial, industrial, and residential customers for more than 35 years. Its Massachusetts HVAC license is active and current in the state registry. Beyond that, there isn't much to go on: Google shows a 4.7-star average from just three ratings, and an HVAC-specific directory shows the same shape — two perfect scores and one four-star rating whose only complaint was about site navigation, not the work itself. The Better Business Bureau gives it an A+ grade, though the business hasn't sought accreditation. One thing worth sorting out before calling: the BBB has the company on file at a Somerville address under owner Dan Galvin with a 1988 start date, while its own website, Google listing, and other directories all place it in Medford. It's almost certainly the same company with an older address on file, but confirm the current location and phone number before scheduling anything. With so few public reviews, this looks like a licensed, longstanding shop that simply hasn't accumulated much of an online presence — a reasonable call for HVAC or refrigeration work around Medford and Somerville, but worth a quick reference check given how few independent reviews exist.
