Best heating and air conditioning pros near Dunbarton, NH

"This company went above and beyond to help us. Our furnace stopped working and we had no heat at all. We called them and Brian came out the next morning and gave us a quote on the spot. Four days later they installed our new furnace and had us up and running in no time. I would heartily recommend this company. I know I will call them again if I have any problems in the future!"

"Everclear called near immediately upon my query through Angi. The technician came out within a few days, was very prompt on the scheduled appointment and took care of my dryer service. They were very reasonable in my opinion and would highly recommend them on all counts."

"Absolutely top notch service and knowledge for the best price around Literally wouldn’t even consider calling another hvac company - thank you Keenan we look forward to the next time we need your services"

"Never having had to hire someone to fix my AC unit only to install it (and the company was not reputable), I had serious trust issues. Action was the only one to contact me of all the suggested companies. That made me even more suspicious! They were able to fit me in for the next day. Hmm, more hesitation. But I rested in Action's good reviews on HomeAdvisor and kept the appointment. I was so happy I did. Mike was fantastic. He was personable and extremely informative. He knows his AC and heat pumps really well. I look forward to having them back in a couple of weeks to clean my furnace and do some cleaning and troubleshooting on a Hearthstone gas fireplace. When one finds a company one can trust, well, stick with them and get what needs to be done, done. I am so happy to have done something so out of my nature, like trusting HomeAdvisor. Thank you, Action Plumbing, Heating, and Airconditioning!"

"Cornerstone IAQ is simply excellent. They arrived exactly (to the minute) as they said they would, showed me before and after duct pix, and offered sound advice on other related actions I could take. They are worth every dollar spent. I recommend them to anyone needing their HVAC ducts cleaned. Hats off to Mike and Jason...."

"I finally got to build my dream garage to store all my tools and have a cool hangout on Friday nights with the boys n a couple coors. Chris came and did everything from the bathroom and the heating system. I will definitely be calling him back to add a mini split in the future. He was professional, punctual and clean. Very knowledgeable you can tell he cares about his clients."

"Kyle is always quick to respond and come out to evaluate, even after hours! He never lets us go without heat or hot water, if he can help it, and for that I am extremely grateful. He is also very knowledgeable in the field of HVAC"
