A Plus Energy Services is a Milford, NH energy-audit and insulation contractor founded by Daniel Ramage in 1997, relocated to New Hampshire in 2000 and incorporated in Hampstead in 2002. The company states it performs home energy audits, air sealing, attic, wall and basement insulation, window replacement and suntube daylighting for residential, multifamily and commercial buildings across southern New Hampshire, and lists Amherst, Bedford, Concord, Dublin, Goffstown, Keene, Manchester, Merrimack, Nashua and Peterborough among the towns it serves.
Reviewers from 2022 through 2025 consistently describe Ramage personally conducting NH Saves energy audits and then completing the recommended insulation and air-sealing work himself, leaving job sites clean and explaining what was done and why. Several reviews get specific about the results: one homeowner who heats entirely with an outdoor wood furnace reported wood usage dropping from about 10 cords a winter to about 6 after roughly $4,600 of insulation work, and others describe warmer homes, reduced oil or gas use, and improved blower-door test results. Reviewers also credit him with knowing the NH Saves rebate program well enough to identify savings other insulation companies had missed.
Two reviews stand out as less positive. One reviewer gave 3 stars because repeated calls went unreturned and they were never able to have work done or evaluate it. Another gave 1 star after an in-home energy audit that, in their account, did not cover every inspection item listed on the company's own website. Everything else in the record, more than twenty other reviews spanning three years, describes a positive, hands-on experience with the same person doing the work.
The company also lists a set of individual energy-science credentials for Ramage, including HERS (Home Energy Rating System) certification, an IGSHPA geothermal installer credential, and training from several energy-industry programs; these are the company's own claims rather than registry-verified licenses, since New Hampshire does not license insulation or energy-audit work as a trade.
Anyone considering A Plus Energy Services should expect to work directly with Ramage rather than a larger crew, and should confirm upfront what an energy audit will and won't include, given the one account of a narrower-than-expected inspection. For homeowners looking for an experienced, personally run insulation and weatherization contractor familiar with New Hampshire's rebate programs, the track record here is strong and specific.
