Heating & Air Conditioning / HVAC near Stow

“Advanced Mechanical Systems did an outstanding job installing our brand-new AC units last year. It was a major project that required multiple cranes and a full crew, and they handled it with impressive coordination and professionalism.

From start to finish, their communication was clear, proactive, and consistent. The entire team remained calm, organized, and incredibly respectful of our business operations while working on site. For a project of that scale, the execution felt seamless.

We are extremely grateful for their expertise and would confidently recommend them. 5 stars all the way.“

“I couldn’t have been happier with the service we received from A&L. From the first outreach, the entire staff was informative, patient, and thorough in their explanations, and did everything they could to make sure I was doing the right thing for my house (replacing two HVAC units with heat pumps). This was not a cheap job, so I appreciated the care that everyone took - especially Sarah and Paul - to reassure me that while this wasn’t the cheapest option, it was the best option. I value honesty and transparency, and A&L delivers on both. A special shoutout to Lucas and Mike who did the brunt of the repairs — they were right on time, respected the property, were mindful of our dogs, etc. I felt 100% comfortable leaving them in the house without me being there. Happy customer!“

“We always have a great experience with Sostilio & Sons. They installed a new furnace and water heater system in our home, and their work was exceptional. They are clean, conscientious, and explain every option thoroughly, ensuring you feel confident in your decisions.

What sets them apart is their integrity and their workmanship is top-notch. If you want reliable, skilled professionals who truly put the customer first, this is the team to call.“

“Our air conditioning went down in a 85-90° week. TAG was able to send someone that day! A young technician named Mario came. He was prompt, friendly, professional. He fixed the problem and explained exactly what had happened and what he did to remedy the problem! As I told him at the time, if there was a 1-5 star rating, I would definitely give him at least 6! Can’t say enough good things about our experience.“

Cathy in the office was warm and attentive, Brian kept everything organized with clear estimates and reminders, and Gabe’s craftsmanship and professionalism were top-notch. Rich has built an all-star company, and it was a pleasure working with him.“

“I recently had the pleasure of working with Marlborough Air Conditioning & Heating Inc. in Marlborough, MA, and I couldn't be more satisfied with their service. From the initial consultation to the completion of the project, their team demonstrated exceptional professionalism and expertise.

They promptly replaced my outdated HVAC system with a new, energy-efficient model. The technicians were punctual, courteous, and took the time to explain the installation process, ensuring I was comfortable with the operation of the new system. They also left the work area spotless, which I greatly appreciated.

Since the installation, my home's comfort level has significantly improved, and I've noticed a decrease in my energy bills. I highly recommend Marlborough Air Conditioning & Heating Inc. to anyone in need of HVAC services in the Marlborough area. Their commitment to quality workmanship and customer satisfaction is truly commendable.“

“Great service! Competitive pricing. Respectful of property. Knowledgeable service. Just a great company!“

“This company continues to impress.
They came out within 24 hours of my call, diagnosed the issue and promptly made the appropriate repairs. The technician walked me through what had been done - coordinating everything with the main office. And not surprisingly, the final cost was not alarming but very fair.“

“We woke up Christmas Eve morning and our heat was broken….It was absolutely frigid and approximately 20 degrees outside and only 40 degrees in the house; it was so cold in the house that you could literally see your breath, inside. We called Regan HVAC and although we were on hold for a little, when we got through, we spoke with Jessica, who was SO nice and understanding. As expected, they were absolutely slammed due to the winter storm the night prior. Jessica explained that they were really busy, but they’d send someone out ASAP. About an hour later, the technician Joe arrived at the house. He fixed the heat within 5 minutes and explained the issue in detail and offered solutions. Although, he couldn’t permanently repair the issue as he didn’t have the parts, he still made sure the heat was working before leaving. He said he had about 13 calls after us to go to, but he didn’t rush the repair and was very clear, patiently answering the questions we had. Really spectacular emergency service, even on Christmas Eve! We greatly appreciate Jessica, Joe and the rest of the team at Regan.Services: HVAC system repair“

“They did an awesome job! The pricing was reasonable and the customer service is great!“

“Amazing service guy. Oil delivery guy is super nice. The office is run by a very nice lady. Love this place“

“I'm a holdover customer from the Dunn oil days. I was nervous when MacFarlane took over, but it has gone very well for me. The two Macfarlane techs who have done service at my home were outstanding. Very experienced, on time, efficient, knowledgeable. I have also had very good luck getting appointments and I like the modern text alerts they use to keep me informed and reminded. Overall, I'm very happy to have stuck with Macfarlane. In these times of shortages of skilled techs I like knowing these folks are there if I need them.“

“I've been using Knight Since I moved to Hudson 3 years ago. Service and delivery are always prompt and efficient. I woke up last night to a 50 degree house and they had a service technician come out at 4 AM to get it back up and running. Can't say enough about how happy I am with them!“

“We called early this morning about a leaking water heater and they were at our door less than an hour later. Ray replaced the water heater in about the same time. Excellent service always from Curley Plumbing. Wouldn’t use anyone else for my plumbing needs.“
