A1 HVAC Plus is Arthur's operation — an owner-operator working out of Middleboro whose customers write about him by name rather than about a company. The written accounts run from 2015 to 2024 and they describe one man's standard of service: in a 2020 review, a homeowner credited appointment confirmations and follow-up calls; another that year said Arthur explained the fault in layman's terms and fixed it on the spot; a 2024 customer fifty miles away had him on site within two days at the height of the cooling season. The work is heating and cooling — central air installation and repair, heat pumps and ductless mini-splits, per its trade listings, which also describe the company as Massachusetts licensed. It carries 4.7 from 44 ratings on Angi. In a January 2020 review, a customer said Arthur rang back minutes after their online request and had a new system in within a week. The older accounts cover the harder calls: a January 2019 review described an eight-year-old boiler that several earlier visits had failed to sort out after the house lost heat over Christmas, and a January 2016 customer with a disabled daughter at home had a dead furnace running again the same day. The complaints are old, and they are about estimates and scope. In an October 2015 review, a customer said the work went ahead without an estimate, included work they had not asked for, and cost $500 for a faucet and two shut-off valves. Another reviewer that month said a price the owner had given over the phone was not honoured, and that they were billed hourly while parts were fetched. In a February 2016 review, a customer called the price high but paid it, because Arthur was the one who came out on the coldest day of the year. For a straightforward AC or heat-pump job around Middleboro, this is a small shop where the owner does the work and picks up the phone, and the accounts of his diagnostic work are consistent from 2015 through 2024. Ask for the estimate in writing, with the scope and how parts time is billed spelled out, before anyone starts.
Although 50 miles from my house A1 was there within two days which was impressive with the "hot" season in full swing. Extremely friendly and knowledgable.. Gave advice for the future of my system (mini-splits) and what I could expect.
Arthur was able to fit me into his busy schedule, and had me up and running in no time. Arthur was very knowledgeable, and prices where fair and reasonable. Would recommend and use his services again.
After my experience with Arthur I would try to hire him for my next home heating or air conditioning needs excellent service great modern and efficient equipment, fast response, attention to detail. thanks for helping me out Arthur. Richard B.Pembroke MA.
Really appreciated the professionalism of Arthur. While my job ended up being relatively small he followed up the next day to make sure all was well. Will be keeping his card for any future needs.
Arthur, was excellent! He explained the problem in laymen’s term and was able to diagnose the problem fast and fixed it. His pricing seems to be very fare and highly recommend him for any AC related problems.
