Heating & Air Conditioning / HVAC near Merrimac

“David's is the BEST! I used Carters in July of 2024 to clean my oil furnace. I have previously used David's Heating & Cooling located in Merrimac, MA. but Carters pricing is much less expensive. Two nights ago I had the fire department at my home for Carbon Monoxide. Not only did the Carters Technician put the incorrect valve on my furnace but he never vacuumed it out. The incorrect valve and the poor quality of work almost killed my family. We were saved by our carbon monoxide detectors and the fire department. Please take this review seriously. Call David's at 978-346-4216 and spend the $300+ to have your furnace cleaned properly. Your lives are worth it! Pierre hands down is the best technician at David's. He's honest, trustworthy and competent. He fixed all our problems for $500. It was well worth it to have peace of mind entering the heating season.“

“Quickly evaluated and fixed the problem with my mini-split AC. They are prompt in keeping appointments, as well. I highly recommend Burke and Sons in Haverhill for anyone with Heating or AC problems.“

“I cannot recommend C&C enough. I have a rental property that had some water damage and the dryer duct had to be replaced. I called Jonathan and he was there within 20 minutes to get me taken care of. I'll definitely be going to them for future needs!Service: HVAC duct & vent installation“

Even spoke to the other company to explain our issue. Also installed a toilet seat while here. A plus service. Will recommend and call again.“

“I don’t often write online reviews, but this experience truly warrants recognition. Shawn recently replaced our water heater, and I couldn’t be more impressed with the quality of his work. The installation was completed efficiently, with great attention to detail, and at a very competitive price.

It’s clear that Shawn is in high demand—and for good reason. I feel fortunate to have secured his services, and I wouldn’t hesitate to recommend him to anyone seeking reliable and professional plumbing work.“

I would recommend Riverside Plumbing & Heating to anyone that needs plumbing work and appreciates professional and friendly service.“

“The boiler installation the Giard team did was great. They showed up on time, walked me through the process. Brought me down to the basement to inspect the location of the new boiler. Actually finished early and walked me through on setting the DHW temp and the controls for the boiler. Can not say enough good things about the Giard team. Thank you all“

“Joe, Kyle, and Ben were professional and kept me informed throughout the process of servicing one furnace and replacing another. I was impressed with the quality of the work and the clean-up. I’ve used other HVAC providers in the past and have dealt with unfriendly technicians who were condescending when answering my questions. Not these guys! I highly recommend Baldini Plumbing & HVAC!“

“Tim is very professional and knowledgeable. We were very pleased with his performance!“

“I had several plumbing items that needed to be addressed shortly after purchasing my home. Dan Dunn Plumbing quoted a fair price. All the services worked on by Ryan and Dillon were completed to my satisfaction. They cleaned up after their work was done and everything was spotless.

Coincidently, our washing machine shut-off valve failed two days before their scheduled visit to the house. We had to turn the main off until they arrived. They worked on that first and within the hour, we had water again! No questions asked even though it was not on their work order. I will be using them for all my future plumbing and heating needs.“

“I have been a customer of Nibroc for almost a decade. If you want to understand this company, look at the about page. It’s humble but the truth.

Russ runs what we need these days. Honest company with solid people. He stands by his work. He had to do my furnace and my central air split back in 2017. His crew did an awesome job and we have kept our oil with him since. Reliable and dependable.

He recently had to find a solution for my central air crapping out in the middle of this heat dome (I hate animals, fried the system). Others would have taken me to town, not Russ. He presented me multiple options with pros and cons. The guy is honest to the T and his whole company runs that way. I appreciate what a rarity Russ and Nibroc are in our world now. Show me one other company where the owner shows up at your door to stand by their work? That doesn’t exist anymore.“

“John and coastal HVAC are awesome - reliable, reasonable and have super fast response times. They have worked on our old house and now our new house multiple times over the last few years and always been great. I’d recommend them to anyone!“

“Very very impressed by PHD Plumbing and HVAC! They came to the rescue after we had a horrible experience with a big box store trying to get our gas range installed! Quick, professional and an absolute pleasure to deal with! Look no further for your Plumbing and HVAC needs! They will be our got to from here on out! Highly Recommended!“

“We have been using Callahan for years and we have had nothing but 5 star service. In about a week from now we will be moving and had an issue arise with our AC. Nick was sent out the same day and repaired the problem in no time...with a smile. I can't recommend this business enough!“

“We love working with Reliant and have worked with them for many years. They are super guys doing wonderful work. They offer excellent suggestions and options but never push things that you don't want to do. We couldn't recommend them more highly.“
