A 2020 customer expecting to need a new compressor for their air conditioner said Dan found that work by a different HVAC company had left an item incorrectly wired. That 2020 customer said Dan corrected the wiring, charged the system with 1 pound of R405 refrigerant, and that no new compressor was needed. A 2020 customer said the tech was prompt, got the part needed and had their furnace running the same day. A 2021 customer said NEXTgen called and came the next day to get the work done. A 2020 customer said he put in a unit and called the price good. On both HomeAdvisor and Angi the company holds 4.9 stars from 8 ratings. Its New Hampshire hvac licence, number MBE2401710, is active on the state registry, with Next Gen Plumbing and Heating LLC as the holder of record.

NEXTgen was very quick. Called me, and came the next day to get the work done.
The tech was prompt, professional and knew what needed to be done. He was able to get the part needed and get my furnace running same day. Definitely keeping their card.
Dan was very professional. He verified that the work performed by different HVAC company lead to an item incorrectly wired. I did not need a new compressor for my air conditioner. He noted that the mistake that was made was probably due to in experience and not intensional. He corrected the wiring and charged the system with 1 pound of R405 refrigerant. The system is working properly. I will definitely recommend him to anyone with an air conditioning issue.
