MAC HVAC

MAC HVAC has been running out of North Billerica since 2009, and the same names keep showing up in its reviews year after year — Mark, Kevin, Chris — the kind of repeat cast that suggests a small, steady crew rather than a rotating group of subs. The company describes itself as family-owned, and its Better Business Bureau profile carries an A+ rating. What the written record keeps coming back to is complex installs done exactly to spec. In a 2023 review, a homeowner described fitting individual HVAC systems to each floor of an old, cramped house — 'not an easy job' by their account — with everything working as requested afterward. In a 2022 review, another described three heat pump systems installed across two years with special routing requests for refrigerant and power lines honored down to the detail, calling it one of the better contractor experiences they'd had in any trade. Speed shows up often too. A condenser died on a 90-degree Friday this August, and Chris had a new capacitor in and the unit cleaned within hours — faster than the other HVAC shops the homeowner had called could even get someone out. In a 2022 review, a Saturday heat-wave breakdown got a Monday morning slot after the shop called back to say something had opened up. And in an early-2026 review, a heat pump issue that came in one morning was resolved by noon the same day. There's one dated complaint worth knowing about: a 2021 review, one star, describes a mini-split installed in a different brand than what was agreed — though it names the business's owner as 'Mack Antonoff' rather than Mark, the name attached to every other review and to the company itself, so it isn't clear the complaint is actually about this shop. Nearly all the rest of the written history here is glowing and spans 2010 through this year, across Google and HomeAdvisor, with Kevin doing much of the recent hands-on work and Mark handling more of the earlier years personally. For a heat pump or ductless install, a stuck AC in a heat wave, or routine seasonal maintenance, this reads like a steady, established call — worth confirming current pricing and lead times directly, since none of the reviews go into cost beyond calling it competitive.
