H.O. Services

H.O. Services is the kind of call people make from a dark house — a Belmont, Massachusetts electrical, plumbing, heating and cooling outfit that the Better Business Bureau describes as a family-owned sole proprietorship going back to 1990, run by Howard Oven. The written record is dated but strikingly consistent: thirteen reviews on BuildZoom, all from 2010 to 2014, describe the same pattern. In a 2014 review, a homeowner with a dead circuit said the crew came out the very next day, explained the problem clearly, and had the power back on quickly. Another 2014 account, about a failing service panel, specifically called out being quoted a price upfront before the work started. Across the run, the words that keep showing up are on time, polite, and thorough — a technician's manner mattered as much to these customers as the fix itself. The Better Business Bureau backs that up from a different angle: an A+ rating, even though the business has never sought BBB accreditation. On BuildZoom, the company shows 84 permitted electrical and building projects and a license it says it verified as an active Massachusetts electrician registration (#13852) in June 2026. Before calling, it's worth knowing the license picture isn't entirely clean: BuildZoom lists a second business license (#34114) it hasn't rechecked since its recorded 2016 expiration, and couldn't verify a third number (#13852A) at all — worth confirming with the state board directly for a bigger job. For a house with an electrical problem, or the plumbing, heating or cooling work that comes with it, H.O. Services reads like a long-running, one-crew operation that shows up when it says it will and quotes the price before starting — just pin down which license covers the specific work being done.
