Alpha Mechanical is a Watertown HVAC company that holds an active Massachusetts HVAC license and a BBB profile listing 28 years in business with an A+ grade, though it isn't a BBB-accredited business and the page shows no complaint counts. The recent written record centers on friction with the office rather than the mechanical work itself. In a 2025 review, a customer described the company doing the minimum and needing repeat visits and repeat charges, and singled out Adriana on the phone as argumentative — that reviewer speculated the business is under different management than in past years. Two reviews from early 2024 describe similar phone-call conflicts: one called dealing with owner Adriana a nightmare over a warm-air complaint, and another simply found the phone call disrespectful. An older 2021 review described being billed for three separate inspection visits addressing the same non-heating air conditioner problem within about a month in late 2019. Not every account is negative — a May 2024 review described a full air conditioning and heating system installation for a condo, with the owner, Sean, described as patient in walking through the options; that reviewer noted having seen criticism of Sean and Adriana online before deciding to write in with a positive account of their own job. What to know before calling: several recent reviewers describe pushback or dismissiveness on the phone, particularly from the office side of the business, and more than one review mentions repeat visits or repeat charges for what should have been a single fix. Given that pattern, it's worth getting scope and pricing confirmed in writing before work begins.
If you want a repair company that does the minimum and makes excuses when they need to come back repeatedly and keep charging you, Alpha Mechanical is a great choice. Also, Adriana on the phone is nothing but argumentative. I shouldn't have to convince you my heat isn't working. They must be under different management because there used to be a very knowledgeable man who was polite, courteous, and highly informative. I called them again for THAT guy, but I guess he's gone. Word to the wise, spend some more money elsewhere and make less phone calls. EDIT: WENT WITH ANOTHER COMPANY AND THEY UNCOVERED THE REAL, MUCH MORE SERIOUS ISSUE. I would've spent WAY too much money paying them to come back over and over just to replace the furnace in the end.
on May 16, 2024 looked for their web site because I wanted to recommend them to a friend and was horrified about some of the criticisms of Sean, the owner, and Adriana, his wife. I used Alpha Mechanical to install a new air conditioning and heating system in my condo. Sean was very patient at educating me about the options. I signed a contract in May 2022. It was difficult to get the equipment as it was during the pandemic but I ordered everything to have it on hand in case my AC failed during the summer. Fortunately it lasted and I was able to replace the entire AC and heating system in September, a year and a half ago. It has worked flawlessly and when we had a problem, caused by my husband, they came and rectified the situation. They are a small operation so it is not always possible to get them to turn on a dime but so far, so good, and I have nothing but great recommendations for Alpha Mechanical.
If it were possible to give Alpha Mechanical zero stars, I would not hesitate. My recent experience with this company, particularly with the owner Adriana, has been utterly disappointing and frustrating. Three weeks ago, I contacted Alpha Mechanical to have my A/C checked due to warm air blowing out. From the outset, dealing with Adriana was a nightmare. She dismissed my concerns, claiming the air was warm because the outside temperature was too cold. Her absurd explanation continued with assertions that no one in Massachusetts used A/C, including herself. Despite my persistence, she refused to acknowledge the issue and instead insisted on her erroneous beliefs. After weeks of unbearable heat and humidity, I reluctantly called again, hoping for a resolution. Unfortunately, Adriana’s attitude remained unchanged. She repeated the same illogical excuses, even misrepresenting the outdoor temperature. Her lack of professionalism, rudeness, and indifference to customer satisfaction were glaringly evident. Adriana’s incompetence extended to her inaccurate assessment of the situation and her disregard for customer concerns. It was only after persistent insistence that the repair crew was finally sent. To their credit, they performed excellently and treated me with the respect I deserved. However, one positive interaction does not compensate for the overall dismal experience. I cannot in good conscience recommend Alpha Mechanical to anyone. Adriana’s unprofessional behavior and lack of knowledge make her unfit to handle customer inquiries. Potential customers beware: don’t be deceived by any positive reviews, as I suspect they are fabricated by the company itself. In conclusion, my encounter with Alpha Mechanical was a lesson in poor customer service and unprofessionalism. Save yourself the trouble and consider an A/C company that genuinely cares about its customers.
Very disrespectful over the phone. Will never hire them now.
From November 18, 2019 to December 16, 2019, because the air conditioner did not heat up, the company’s three inspections cost a total of $590. In fact, the three repairs are less than a month. He should no longer charge, but they are the first Charges will continue for both the second and the third time
