Medford Wellington Service Co.

Medford Wellington Service Co. runs HVAC work out of 17 Locust St in Medford — one of three addresses the Better Business Bureau lists under the same corporate name, alongside North Billerica and Rocky Hill, Connecticut. The BBB puts the company's history at 59 years, and it carries an A+ grade there despite never seeking formal accreditation. Its Massachusetts HVAC license is active, and on Google it holds a perfect 5-star rating — but that rests on just two ratings, a count an HVAC directory listing echoes almost word for word. That thinness matters, because a separate account describes a heating repair that didn't actually fix the problem, with another company later called in to sort it out. There isn't much else here to weigh that complaint against: no work photos, no detailed service history, no deeper run of independent reviews. Before booking, it's worth asking exactly what a repair covers and what happens if the issue isn't fully resolved. An active license and a clean BBB grade make this a reasonable option to call for routine heating and cooling work in Medford — just get the scope of any repair in writing given how little independent track record backs up the good rating.
