Heating & Air Conditioning / HVAC near Sudbury

“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!“

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

“Awesome. It was a slightly complex job and they kicked it out of the park. This is exactly on point.“

“Our tech was prompt and efficient. He was very knowledgeable and explained things completely. Very personal“

“Very professional company for HVAC needs. The staff members and technicians are competent and courteous. I have been using them for a couple of years and will continue to work with them if they keep up with the high standards.“

“Santiago was very professional, polite and thorough
Great service, explained all the details well. His professionalism, attention to detail, and commitment to patient satisfaction put me at ease throughout the entire process.“

“We absolutely loved working with Wellesley Plumbing & Heating. They were incredibly responsive, assessed our issue right away, and they were able to complete the work rapidly. They went above and beyond when I had purchased the wrong unit for the repair. They were able to find the right fit quickly, and made the installation without issue. I would recommend them to anyone looking for plumbing support in the Wellesley area. A+ service and professionalism!“

“Joe Medeiros was really great! He was incredibly helpful and even offered to take care of some other things on my list for me that I was unaware a plumber could do! He was able to remove my kitchen appliances for minimal fees, so I did not end up having to call junk removal for an extra cost. He was also extremely helpful because I live in a condo complex where the plumbing is unified, and he was willing to connect with property management on figuring that out for me. Extremely professional, polite, and went out of his way to be helpful, very grateful for that! The whole team at Flaherty has been great!“

“Amazing experience! Came out on short notice during the latest heat wave and fixed everything. Would highly recommend.“

“This was my very first service experience from Ideal Air and it was a great one. This was a last minute emergency appointment that they accommodated on a Sunday. Odean from their team came over promptly and did a great job of diagnosing the problem, he took the time to explain things to me in a manner I could relate/understand it easily. He was able to connect with the Navien support team during the appointment, they troubleshot the problem together, figured out the root cause and the right fix to the problem. My heating problem was resolved in a matter of hours the same day. I will definitely rely on Odean for help in future as well.“

“Quick response to unexpected burst pipe. And they don't overcharge for their work, so I continue to use & recommend.“

“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.“

“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.“

“Target Air Systems is one of the best reliable and honest service providers we have ever worked with .

They extended technical expertise and professionalism services.

They provided exceptional and quick service and they fixed the problem quickly. They were very kind and honest in dealing with their customer. We highly recommend them“

“It is January 2026, the day before a huge snow storm of 1 - 2 feet of snow. One heating zone was stuck open and not working. The indoor temperature was 79 degrees in January ! I called Coan Oil for emergency service at 8:43 am and Dave arrived at 11:05 am. Dave immediately inspected the furnace and the valve was replaced. Work completed by 11:30 am. Kudos to Coan for fitting me in on a busy day before a huge snowstorm and we are Grateful to Dave for his Knowledge, Professionalism and very friendly demeanor. Thank you Coan for having Dave on your service team.“

“Our furnace shut down this week on the coldest day of the year. Called J.W. Heating and AC. Josh showed up that day within a half hour, diagnosed and made the necessary repairs. What a great experience. He takes the time to figure out your problem and repair if he can, doesn’t take the easy way out and saved us money, not once, but both times he came out to work on our furnace. I highly recommend Josh and his company.“

“Mike is fantastic! He was very thorough and explained everything. He is super reliable. I would highly recommend him!“

“Have worked with Bob and his son, Charlie for almost 20 years. As always, prompt service, and great work at a fair price. He’s the only one we call! Always a great chat too!“

“Came home yesterday Friday August 8 at 3:00 pm to a flooded kitchen and basement ... thermostat not working ... a disaster! Called Acton Refrigeration ... had a technician there within an hour and up and running within 45 minutes .. fantastic job ... thank you so much!“

“This is an exceptionally good company! From planning our heat pump system for our residential home to execution, helping with receiving the refund from the State, and following up with questions and additional requests from us after installation, everything was smooth, friendly, and of high quality. They are competent, helpful, reliable, quick to respond, and always willing to adapt to the customer's needs. Fantastic. I have recommended them to friends and would recommend this company to everybody interested in switching their heating/cooling system to heat pumps. The heat pumps keep the house warm and comfortable even during cold Massachusetts nights without problems.“

“Huge thank you to the Martell team—they always show up promptly and ready to help whenever our dental office needs them.

James and Will, who came out to service our AC units, were professional, efficient, and incredibly thorough. They cleaned all four condenser units (with water access provided) and replaced all indoor filters. The difference is already noticeable; our space is much cooler and more comfortable.

Highly recommend their services to anyone looking for reliable and knowledgeable HVAC support!“

“Working with Rich Demelo, owner of Demelo Plumbing, was an outstanding experience. From the very beginning, Rich’s knowledge, leadership, and positive attitude set the tone for the entire project. He was a true professional and a pleasure to work with, making our master bath renovation feel smooth and enjoyable from start to finish. His team reflected his high standards as well. 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.“

“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!“

“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.“
