Excel Mechanical is a Tewksbury, MA HVAC and plumbing contractor, self-reported operating since 1996 (30 years), with a second office in Sandwich serving Cape Cod alongside Greater Boston and southern New Hampshire. It offers heating, air conditioning, ductless mini-splits, and full residential plumbing, including 24/7 on-call emergency service. The company is BBB-accredited with an A+ rating and carries a large volume of detailed, positive reviews across Google and Thumbtack. Reviewers across several years consistently name the same technicians — Ivan, Miguel, Randy, Bill, Peter, and Mike among them — describing thorough diagnostic walkthroughs, protective booties worn indoors, and clear explanations of the work and any code or permit requirements. The company's emergency response also draws specific praise: a 2022 review described a next-hour response to a burst pipe, and a 2023 review described next-day service during a boiler failure and burst pipe in a -10-degree cold snap when other plumbers weren't returning calls. A few things are worth confirming before booking. The state registry lists Excel Mechanical's Massachusetts HVAC license (650-SM-B) as expired. A March 2026 review described a mini-split installation leak that caused ceiling damage, which the company offered to repair before it stopped responding to follow-up calls. A Better Business Bureau customer review separately describes a wrong PTAC unit being installed with prolonged difficulty getting it corrected. Two older reviews, from 2023 and 2024, described high quotes for AC replacement or maintenance without work being performed on the spot. For routine and emergency HVAC and plumbing work, Excel Mechanical's technicians draw strong, specific, repeat praise. Given the license status shown on the state registry and the unresolved cases above, it's worth confirming current licensing and getting a clear resolution plan in writing for any installation work before it begins.
“Excel Mechanical was great. They used to be based in Somerville on McGrath Hwy but moved to Tewksbury for obvious reasons. Get a quote through MassSave, then go get two more once you have that. You can use your MassSave quote to negotiate the other two down. Ultimately though, you likely want someone that will make the rebate process easy on you. I found Excel to help a lot.”
Peter did a fantastic job…both times - with repair as well as HVAC maintenance. We have 1 repair awaiting delivery of space part…but overall a great job thus far.
On time, let me know when he was on his way, pleasant, efficient. I’d be happy if Peter were my assigned technician in the future.
Miquel was prompt, friendly, professional and did a thorough job!
Mike did a fine job here. He worked very hard. The mini split is all set but unfortunately the main AC is faulty and he had to turn it off and let ice melt. He had said someone would call me but no one has it is rather hot in here and it is a weekend. We have had trouble with this unit and had to live without AC a month ago for over a week. I hope this doesnt happen again. No fault of Mike. He did fine.
very professional, efficient, and personable
