Heating & Air Conditioning / HVAC near Exeter

“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.“

“They are AMAZING! I’ve been using them for the past 7 years. They do great quality work that you immediately notice. Their professionalism is also second to none. Highly recommended.“

“They worked with me during this hot 4th of July 2026. AC stopped unexpectedly. Just need a capacitor replaced.The girls in the office are amazing! professional and very helpful, and very friendly! I won't use anyone else. They replaced my AC unit 6 years ago. I received a quote from another BIG shop for 3x what Kearney charged. They (Crny) wanted to replace my entire system heating/cooling system which was not necessary. Kearney was honest and 6 years later 100% correct & honest. No hard sell. Just honest, clean, reasonable group! Very grateful for your help!“

“Very good service from Abram. PROMPT ARRIVAL - he arrived at the time quote. This makes for planning your day much simpler. Reliability is a hallmark of a good company. Highly recommend.“

“Highly recommended! From estimate to install of a heat pump in under two weeks. Clear communication, excellent products, and the best price in town. They stand by their work and have the longest warranty/free service follow-up period of anyone we found.“

“James was very professional. He set up somebody to come out Friday and fix my nightmare although a plumbing job. I cannot wait to have it done and over with. James was very nice and explained everything in full detail.“

“DJ was really great! Prompt and knowledgable. We will call him back for future projects.“

“Dan and Jay worked as a good team and they were knowledgeable and courteous. We are very satisfied with our new heat pump system.“

“As a general contractor you can only be as good as your sub-contractors. Dan's team always shows up on time, do great work and clean up after themselves making it easy for us to provide our clients with the best level of service and quality that we can.“

“Excellent service! Our HVAC consultant is very kind, professional, and knowledgeable. We highly recommend Main Stream Mechanical.“

“Great and easy to work with. Replaced my AC unit last year And just did my furnace this year. Both are working perfectly. They advised me correctly on the correct products for my house. Will only be working with them in the future on all HVAC needs.“

“I’m a local contractor and I’ve been using this company for years. Kevin Hart and his team never drop the ball on anything, they bring the energy every time and complete the mission no matter how challenging. They are efficient on schedule and fair. I will recommend them to anyone.“

“We have worked with Todd, Marvin, Rob, Andy, Dave, and Jose! Everyone has been extremely helpful, friendly, and professional. We truly appreciate their quick (and reliable!!) ability to problem-solve any issues that have come up in the home. We have had them resolve issues with our oven’s exhaust system, solved a complex heating issue, and plumbing for an irrigation system. APH have become our “go to” guys. Thank you so much!“

“The outcome was great. Took too long for outcome to happen. Was not in his control. It was a warranty issue and paperwork was submitted immediately. Took 35 days in the dead of winter to finally get furnaces replaced and running.
Mike was as frustrated as we were. The work Mike did amazing work and once he had everything inline he did it in a timely fashion around Mother Nature. I would recommend diamond mechanical again. He is only one person operation but worth working with. My only issue I had at all was communication during that 35 day period.“

“Anthony and his team just replaced both my heating and a/c systems. Professional, efficient, friendly and finished the job ahead of schedule. Would not hesitate to recommend them for any plumbing or HVAC needs. I will have them continue to service my new systems.“

“I was impressed with S-NICK Dryer Vent Cleaning & Air Duct Cleaning Services Hampton, NH. They were very prompt and efficient with providing the estimate and setting up the service appointment. Kevin and Ben were very pleasant and professional. They did a great job cleaning the air ducts, bathroom fans, and dryer ducts. They also documented the work so I could see the before and after differences. I would definitely ask for their service again.“

“Peter Leighton is an angel and honest as the day as long! We live in a disposable society where everybody wants to replace everything, but Peter believes in the value of service, maintenance and replacing parts. He had been maintaining our heating system for the past 12 years in West Newbury and I recommended him to an elderly client in Merrrimac who had been getting quotes up to $17,000 for a new heating system. When I arrived to her condo yesterday they were sitting and chatting at her kitchen table. He was explaining how worst case scenario she just needed a new hot water for 3K and he would be happy to maintain the old system. He didn’t even charge her for service call/consult! Don’t know what I’ll do when he retires ?“

“Great experience with Dowling! I had received quotes from 5 different companies; one looked at our job for 5 minutes and left, and the others provided various load sizes but no explanation as to why they recommended that size. Dowling did their due diligence to look at all of our space to calculate the appropriate load size for our unit as well as the ductwork layout (both the vent locations and the duct lines to minimize ceiling impact) so the system is as efficient as it can be. They're willing to explain why they made their recommendation and educate me better, which was important to me considering the investment. Ductwork and installation went smoothly and the technicians worked through a 100+ degree day to get the AC turned on (one tech actually finished our job and left for another at 6pm that same day). Would highly recommend Dowling. They educate, provide reason behind a recommendation, and the pricing is competitive. All well worth it to gain peace of mind that I have the best system and layout for my needs.“

“Atlantic Fuels provides excellent customer service. My oil burner ceased to operate. Chris the driver agreed to check it during a delivery this week. I was in NY. He informed the office it wud not start up. I drove up the next day to meet Travis the technician for service. As always, he is friendly, professional and knowledgeable. He diagnosed the problem immediately. His knowledge base is impressive having worked in this capacity for years. Last year he did a tune-up and asked if he could move the file cabinet back so he had more room to do a better cleaning of the furnace. That sealed the deal. I then knew I was working with an individual committed to doing a thorough job. He uses his time efficiently. He expressed how he loved his job. Afterwards, he cleaned the area he was working in being respectful of my place. Does work performance get any better than this? Madison and Kristen are also very dedicated to making sure performance of everyone has a positive outcome and customers are happy. Atlantic Fuels has an extraordinary team dedicated to providing the very best customer service to their clients. Thank you!“

“Most honest nicest person did such a great job for us in such a scary moment where we had no heat. He was right there for us. Couldn't ask for a better heating plumbing specialist. He is above five stars. Thank you so much! Extremely grateful so knowledgeable at what he was doing. Would recommend him to everyone I know“

“Had a new heat pump installed for heating / cooling, new thermostat as well as service for a gas furnace. Great service and easy to work with. Would absolutely recommend to anyone.“

“We've relied on Clint for many years now and always appreciate how he explains what is happening with our system and how hes going to fix it. Very friendly and professional, would not hesitate to recommend him to friends and family. If you are a client of his you are in good hands.“
