Aquion Mechanical Group LLC

Aquion Mechanical Group LLC delivers plumbing, heating, and cooling services across eastern Massachusetts and southern New Hampshire, with a physical base in Burlington. Founded by owner Brian Donahue, the company has accumulated more than 15 years of specialized trade experience and maintains full licensing for plumbing, heating, and cooling work in both states. The business holds a perfect 5.0-star rating derived from 31 verified customer reviews, positioning it among the highest-rated mechanical contractors in the greater Boston metro area. Homeowners in Stoneham, Burlington, Lincoln, and surrounding Middlesex County communities regularly call on Aquion for both routine maintenance and emergency repairs.

What distinguishes Aquion from larger competitors is Donahue's personal involvement on every job site, he never dispatches anonymous subcontractors, giving clients direct access to the expert making decisions. The company specializes in boiler and furnace systems, including tankless water heater conversions and steam boiler retrofits featuring Low Water Cut Off and Automatic Water Feeder installations. Their water filtration division installs whole-home systems targeting specific contaminants, while ductless mini-split installations provide cooling solutions for older homes lacking ductwork. The maintenance plan, priced at $25.99 monthly, includes annual combustion analysis and priority scheduling, with waived off-hours emergency fees for subscribers.

Customer stories from verified reviews reveal the range of situations Aquion handles. One Burlington homeowner recounted how Brian arrived within hours to install a new Low Water Cut Off device and flushed their steam boiler the same day, work completed at reasonable pricing. A Lincoln property manager facing a 24-hour municipal deadline described how Brian responded on short notice to repair a failing boiler before a tenant could move in, meeting the city's exacting timeline. Reviewers repeatedly credit Donahue with avoiding unnecessary upsells, providing upfront pricing before work begins, and taking time to explain code compliance issues affecting remodels.
