Dynatemp HVAC Services

Dynatemp HVAC Services is an Essex-based heating and cooling contractor founded in 2001, working on furnaces, air conditioners, heat pumps, boilers, and ductless mini-splits across eastern Massachusetts. Reviewers name technicians Joe, Joey, and Tom directly across jobs spanning routine maintenance to full system replacements. In a July 2026 review, a customer described a whole-house conversion to a mini-split heating and cooling system, calling the team extraordinarily responsive and professional from design through coordination. In a July 2024 review, a customer said Tom took time during the company's busiest heatwave season to find a quick fix when their central AC failed, calling him a lifesaver. In another July 2026 review, a customer said the crew found and fixed a problem during the same visit as a routine maintenance call. One reviewer, in a July 2026 review, said they'd used Dynatemp for over 10 years across three units in two properties with no problems, and credited Joe with diagnosing an issue another company had missed. The company's technicians are NATE and EPA certified, and its Massachusetts HVAC license is active on the state registry. The one recent complaint, in a July 2026 review, was about an eight-week wait for a replacement circuit board, with the customer asking whether the manufacturer could be called directly to speed things up — a parts-supply issue rather than anything about the work itself. For routine HVAC maintenance, an emergency repair, or a full mini-split conversion, Dynatemp's two decades in business and specific, repeat-customer reviews make it a solid option — ask upfront about expected turnaround if a part needs to be ordered, since one recent review flagged a long wait.
