HVAC reviews in Hudson, Massachusetts

Above and beyond! -From wilkins street

Didn't want to come out to service - said to call our septic company in the morning even though we wanted immediate assistance.

Excellent service. Very knowledgeable and friendly. Have dealt with them over many years and they have never disappointed. Highly recommend them for sales and service.

Honest, hard working, and efficient. They did exactly what I needed on my hvac. I would highly recommend and definitely use again!

We had a small job to replace a leaking 1" ball valve in our office building. We called another contractor who is 1/2 mile away from us. They said they would come by to look at it. We called them several days later to check on the visit and got no response to our voice mail. We then called Demelo on a Monday. Their plumber arrived at 8:00 Tuesday morning as promised and he was out of here by 9:30, having done an excellent job. Highly recommended.

I cannot say enough about this company from its high quality work to their amazing staff. Always a positive knowledgeable person on the other line to answer your questions and there workers do amazing work i use this company at my facility all the time if you want the job done the correct way call Demelo i highly recommend

Just had Aiden at my house yesterday. He was awesome very thorough and did a great job and great attidude!! Thank you!!! Great job!!!

Steve was very professional and helpful above and beyond. He went over everything with me and made sure everything was running perfectly. Arianna was very friendly and accommodating. I would highly recommend this company.

We purchased our air conditioning from them...units are excellent. We also purchased the eco-plan that has 2 cleanings a year on the units. Very satisfied with them.

Amazing - they came in to do a cleaning service of our heating & a/c system and did an amazing job. The also were very helpful explaining and clarifying all the questions I asked. I highly recommend!

Had some central air issues in our new house, these guys were very responsive and did a great job. Didn’t sell me parts I didn’t need, explained in layman’s terms what was going on, and got me back up and running again. Highly recommend them!

Demelo HVAC installed a new Combi Boiler, replacing an old furnace using the mass save early replacement program. Both his office staff and the installers were great. Friendly and professional.

Wonderful experience, extremely reliable and so helpful. Resolved my plumbing issues with ease and professionalism. Gabe was wonderful and I highly recommend him and this business.

Aiden arrived on time and ready to solve the issue. Three flex ducts had to be repaired, patched or reconnected. He explained the problems, repaired everything and cleaned the work space. Highly recommend Demelo to others

If you want a job done quickly, professionally, and up to code, this is the place for you. From the office staff to the technicians they are professional and informative. They have always been a go to for our company for any large projects or emergency repairs.

This is from Dr. He's primary care for adults, We are very grateful for prompt service Mr. Demelo provided couple weeks ago, the heater in the clinic was not working full strength, we have called Demelo Heating, they were able to fit us in their busy schedule the very next day. Thank you so much.

I'm so thankful for Josh at Demelo for fixing my AC. Right in the middle of a hot spell and the rate was still very reasonable. He gave some great advice too on how to maintain the system. Would highly recommend this company.

They did a good job but it is hard to believe that prices are fair.. $200.00 for 2 shut off valves and $185. An hour for service with a minimum of 2 hours....$370....cost me $679. Total for the job....way over priced...i do not believe that it should cost this much for what was done....i will not be calling again......

Over charging everything as other reviews mentioned, $185/hour PER WORKER, the “inspection” hour can’t be deducted even you decide to let them do the work which it’s so unusual, and they charge an whole hour even it’s not a full hour. There are many other business out there, avoid this one.

After looking at the aggressive, attacking and completely incorrect info response from the owner, all I can warn everyone is be aware and choose wisely!

Came out twice on emergency calls totaling over $750 and actually made things worse. Then tried to upsell me on getting a whole new system. Another company came later and had to undo their changes + actually fixed it for $600.

This is a great company. Steve did a terrific job replacing a clogged pipe. He was professional, punctual, clean and tidy, and pleasant. I have already called the company back to schedule more jobs with them. I highly recommend them!
