Verified record
TSL H.V.A.C /R Mechanical is a Medford, Massachusetts HVAC contractor working on central A/C, heating, and furnace systems. In a March 2019 Angi review, a customer called the service excellent, very responsive, and fairly priced — the only written account on file, so there isn't much of a track record to weigh yet. The company's own material makes conflicting claims about how long it's been around: its About Us text says 'over 14 years of industry experience,' while a separate highlight badge on the same page lists 26 years — worth asking about directly. For a homeowner in Medford needing central A/C or heat pump work, TSL is worth a call, but with just one review on file and that tenure discrepancy unresolved, getting a written estimate and asking a few questions up front is the sensible move before booking.
