Diamond Pro HVAC Services Inc

Diamond Pro HVAC Services is an Ipswich, MA HVAC business built around one name — reviewer after reviewer describes calling and getting Mohammed himself, from the first call through the finished repair. Two things keep coming up: he shows up fast, and he doesn't pad the bill. Across dozens of Google reviews running from 2024 through this year, the same pattern holds. Customers call about a dead furnace, a leaking boiler, or an AC unit that quit mid-heatwave, and he's often out the same day or the next morning — one customer described calling the night a boiler failed and having a new one running by the next day. On price, reviewers are specific rather than just grateful: several say the final invoice matched the upfront quote, and more than one mentions he skipped an easy upsell — deep-cleaning a mini-split without pushing a replacement, walking a customer through a fix over the phone instead of billing for a visit. A Reddit poster in a North Shore community thread this August said much the same: a fair price, a clean install, and quick answers to follow-up questions. The work itself spans the everyday HVAC calls — central AC repair and full-system replacement, furnace repair and replacement, boiler service, mini-split cleaning and installation (including a Mitsubishi heat pump job), and ductwork on new installs. Several customers have called on him repeatedly over two to three years for seasonal maintenance, which is its own kind of vote of confidence — people don't keep coming back to a contractor who let them down the first time. One thing worth knowing before you call: in a July 2024 review, a customer described a rough stretch during a heatwave — their AC failed while he was out of town, and it took several days and a follow-up call before they could reach him. It's a single account rather than a repeated pattern, and nothing else in the record echoes it, but it's a fair thing to ask about if guaranteed emergency turnaround matters to you. For routine HVAC work — a furnace on its last legs, a mini-split due for its yearly cleaning, an AC making noise it shouldn't — this reads as a business people in the Ipswich area keep calling back and keep recommending to friends. Just confirm response time up front if you're calling during a heatwave or cold snap, when demand runs highest.
