"Fixed my poor ventilation of my dryer duct. Don't know how effective the hvac duct cleaning was. I figured it didn't hurt to do it once since it's never been done but mostly purchased deal for dryer duct."

"The owner called to let me know the crew would arrive in approximately 45 minutes and they showed up on time and got right to work. Jacob, the owner and I met to discuss options for additional work, which I agreed to. They started vacuuming up the old insulation and during the process I was shown pictures of the clean attic floor and informed what room they would be working on next. They sealed around all the openings in the attic to the HVAC vents, plumbing pipes, etc. All my questions were answered to my satisfaction. Once the job was complete and new insulation blown the crew cleaned up and loose debris in the garage and driveway. I am happy with the crew and their work."

"Repaired my ac and is working fine"

"Our thermostat went out, tried replacing it ourselves and then our heating wasnâ t coming on anymore. Gave NexGen a call and they got someone out the next day before the cold front came through. John came and took a look and found and fixed the problem quickly. He checked to make sure everything was wired correctly on our thermostat, and that everything was running smoothly. He also informed us of some cleaning that needed to be done to our system to help it run more efficiently, and offered the service to get it all cleaned up while he was there. All in all, NexGen was quick, informative, friendly and affordable. Highly recommend!"
