Evolved Mechanical is a Malden heating, cooling and plumbing company that Greater Boston homeowners call for heat pumps, mini-splits, AC repairs and furnace replacements. Its site says it is family-owned, opened in 2003, and was founded by Jason Moriarty, who trained in heating and cooling in Cork City, Ireland. Google shows 4.9 stars from 337 ratings. The state registry shows Massachusetts hvac license 12566-SM-J1, held by Jason T Moriarty, as active. A July 2026 customer whose AC would not turn on had two technicians out within a few hours, and listed the prices: $189 for the diagnostic visit, about $410 for a contactor and about $420 for a capacitor. Another July 2026 customer said the technician, Eoghan, stayed until almost 7 pm to finish a complex repair during a heat wave. In a January 2026 review, a customer whose furnace failed before a cold week had a dual-stage system installed over a Thursday and Friday. A May 2026 customer gave 2 stars after weeks of unanswered calls and emails and technicians who did not show when promised for a heat pump and drain line, and hired another company. In July 2025, a Google reviewer gave 1★ saying a company driver nearly ran them off the road while texting, made an obscene gesture at them and littered out the window. In a February 2024 r/malden comment, a customer with 8-zone mini-splits praised the pre-sale process with Jason and called the pricing very reasonable, but said the installation was a comedy of errors. In an October 2021 review, a Medford customer said the May 2021 heat pump install went ahead without permits, fixed only after months, and that the installed equipment did not match the model on the quote, so a MassSave rebate was rejected.
“[Evolved Mechanical](https://www.evolvedmechanical.com) is local and highly recommended.”
“I second this, Evolved installed my heat pump. Great company & their owner is one of the more knowledgeable people ive met regarding Heat Pumps.”
“Mixed experience with Evolved Mechanical: 8-zone mini-splits for a large house. The pre-sale process with Jason (the owner) was outstanding, and pricing was very reasonable. Installation was a comedy of errors. And I have not been at all delighted with the service after the sale.”
“Another recommendation for Evolved! They’re fantastic.”
“Another recommendation for Evolved. I’ve worked with them twice. They provide excellent, honest service.”
After having a different company two months prior to Evolved Mechanical, I was pleasantly impressed with the knowledge, professionalism and care Matt and Anne took not only in explaining everything to me but in replacing things that were moved to do their job. I would highly recommend this company for HVAC service. I also like the ideal of having plumbing, electrical and HVAC all under one roof which was not the case for me in the past.
I absolutely recommend these guys. They are punctual, clean and polite. GREAT JOB.
Super easy to get a mechanic out within a day or two of requesting diagnostic. The mechanic was very thorough and my AC is back to basically normal! Eoghan took his time ensuring the system was reading appropriate levels (pic is BEFORE he did actual service repairs) and really explained everything well. We signed up for the maintenance plan immediately and happy to have this as one less thing to think about as annual checkups. Great, friendly service!
AC wouldn’t turn on and Evolved Mechanical sent two technicians within a few hours. Matt and Anne came and fixed the issue! Even if they hadn’t fixed it, I was super appreciative that they took the time to explain the issues, answer all questions, suggest ways to keep up w maintenance, etc. They also went to go buy replacement parts and problem solved their way through various blockers. Would highly recommend Evolved Mechanical! Pricing was $189 for the diagnostic visit $~410 to replace the contactor $~420 to replace the capacitor
They're outstanding! My AC went down during the heat wave and my dog with heart disease was really struggling to stay cool. It turned out the problem was quite complex and required a part that was not easily available. Despite that, they consistently prioritized my case and repaired the system as quickly as they possibly could. Huge shout out to Eoghan, the technician, who stayed until almost 7 pm to make sure the job was finished, and we didn't have to wait another day. He was incredibly pleasant and kind despite having to do the repair in intense heat and sun. A+ company that actually cares about their customers.
