HVAC & Air Conditioning Contractors in Londonderry, NH

"I couldnâ t have asked for a better experience. Losing your central air conditioning during a 10-day heat wave is miserable. As miserable as my problem was, within 72 hours of making contact with Next Gen, I had a brand new air conditioner installed. There was no hassle, no delays, everything promised & paid for was delivered. Dan from Next Gen was great to work with. I am a happy & satisfied customer. I will certainly call Next Gen for any future HVAC needs."

"Hysen is an excellent plumber and person. We reached out to him to take a look at the furnace and boilers of a home we bought; he accommodated our schedule to meet with us on a Sunday, sent a fair quote promptly, and less than a week later he diligently worked a very long day to finish the tankless water heater installation. He is also very responsive, which was such a pleasant change from other contractors we've worked with.
