Heating & Air Conditioning / HVAC near Henniker

“Patrick was knowledgeable and willing to explain and answer questions. He didn't try to sell us anything more and gave us tips on how to keep our furnace in great shape.“

“AGS helped us replace our old hot water heater, and they were fantastic from start to finish. Everyone we spoke with was super friendly and helpful, and they made the whole process easy. They explained our options clearly, didn’t try to upsell us on anything, and got us scheduled quickly.

On the day of the install, the technicians showed up right on time, were really professional, and respectful of our home. They did a clean job and made sure we understood how everything worked before they left. It’s been working perfectly ever since—no issues at all, and we’re so happy to have reliable hot water again!

Honestly, it’s hard to find a company that’s both good at what they do and great to work with, but AGS really is. We’d definitely call them again and wouldn’t hesitate to recommend them to anyone who needs HVAC or plumbing help.“

“I called Ben and he came the following day. We have a rustic log home and I was concerned about what the outside installation of pipes and outside unit would look like. Ben installed 2 mini-splits inside our log home and placed all the pipes hidden in the corner of 2 closets. There's no visible pipes, wiring inside or outside our rustic log home. Ben and his awesome crew did an OUTSTANDING QUALITY JOB. I want to add they installed our mini-splits in 4 hours on a Sunday afternoon. Our electrician came the following week and Ben came on that same day to test the units and show us how to run the units. Thank you, Nichols Heating and Cooling LLC for a great experience.

“Sean has been our go to for the past 7 years. He’s been reliable, kind, professional, and very reasonable. Highly recommended!!“

“Very friendly and always responsive, they are the most expert and efficient problem solvers of any plumbing and heating business we’ve ever used. We’ve had repairs and installations done by them. Top notch!!!!!“

“On purchasing our new-to-us 120 year old home, it became immediately clear that the heating system was not only breaking, but also not sufficient to actually heat the building and grossly inefficient to the point that it would bankrupt us if we kept things as they were.

Working with Kyle and Pete, we figured out a conversion plan to Gas with Mini Splits for each apartment unit. They were creative, respectful, professional and hard working to solve our problem and get everything installed.

I couldn't ask for a better team and I would recommend them to anyone and everyone.“

“Nick was very nice to work with. He is efficient and professional. He is very neat and cleans up before he leaves. I would have him do work for us in the future.“

“Unlike a couple of idiots including my brother John , I think Jim is very competent and reasonably priced“

“Val from AirMaster Heating & Cooling was exceptional! Not only did he provide a very competitive quote, but he was also incredibly responsive to all my communications. He arrived exactly on time, demonstrated meticulous attention to detail throughout the entire process, and made sure everything was spotless when he finished. The system he installed is working flawlessly. After seeing his outstanding work in another home in NH, I didn't hesitate for a moment to call him for my house in MA. I wholeheartedly recommend him for anyone seeking top-notch service!“

“Aaron and his team performed absolutely outstanding service! From start to finish, this company exceeded all expectations. The team was punctual, professional, and incredibly knowledgeable. They diagnosed the issue quickly, explained everything clearly, and completed the work efficiently. Not only did they fix the problem, but they undid the bad work of a previous company who botched the original job. It's rare to find a company that combines skill, honesty, and great customer care—these guys nailed it. Highly recommend to anyone needing HVAC services. Thank you for the amazing work, and cannot wait to have you back again to service our furnace and AC yearly for tune ups!“
