East Coast HVAC & EC Electric

East Coast HVAC & EC Electric, based in Dover, has built up 316 reviews across four platforms and a 4.9-star Google rating from more than 1,600 ratings — a volume that puts it among the most reviewed heating, cooling and electrical shops in the area. The reviews describe a roster of named technicians rather than a single owner-operator, and the business carries a BBB A+ accreditation. The specifics repeat across dozens of separate calls. When a customer's minisplit sprang a leak, technician Kaiya came out the same day and fixed it, even though the unit had been bought from another vendor — the customer says East Coast became their go-to HVAC company as a result. Another customer, working with the shop since 2020, describes technician Walter showing up punctually for annual maintenance and taking his shoes off inside without being asked. When a homeowner came back from vacation to a 48-degree house, Trevor Doucette diagnosed the problem and got the heat back on. Elsewhere, Mathieu Bergeron returned to fix pipe joints that had been leaking since East Coast installed the boiler itself back in 2019, and on another visit resolved an issue that had bothered one customer for over a year. On the electrical side, in a 2024 review a customer described Aaron installing a dedicated circuit for a new garbage disposal, calling him prompt and thorough about explaining the work. Not everything is spotless. One five-star review still flagged a phone line that rang out to a busy signal with no way to leave a message when the customer tried to confirm an appointment. And a Reddit comment from a New Hampshire forum, without any specifics, warned other users to stay away, citing unnamed "shady characters" among the staff — a single, unconfirmed account against hundreds of detailed, specific ones. For HVAC, AC, boiler or electrical work around Dover, the specific, repeat-customer accounts and the willingness to come back and fix old work make this a strong option — worth asking about the office phone line if scheduling matters, and weighing the one unverified online warning against the depth of the rest.
