Recommended Customer Reviews

We had a clog issue with our dishwasher. I called to setup an appointment and they were able to send a technician the next day. The technician was very friendly and helpful. He was able to fix the clog and also took the time to answer any questions. I would recommend NexGen, great experience.

The lady who set up our service was friendly and personable. I spoke to a couple ac repair vendors and her kind personality is what made me choose NezGen.
The man who fixed our AC arrived when expected. He was friendly and efficient and got our ac running nice and cold!
We just purchased our home and made the mistake of making an appointment before we consulted our home warranty. So we had to pay out of pocket for a $700 t
repair. But it broke during the wild heatwave and when there were fires in our area. So we didn't have a lot of time or patience for red tape. In the future I will check first. In the end we got what we needed.

If you're looking to add, replace, or service your A/C and/or heater, I could not recommend a better company. From start to finish, my wife and I were kept abreast of progress, days schedule, and the care of our home was white glove. The crew Nathan, Ivan, Jeremy, JR, and those not mentioned were the consummate professionals. I'm sitting in my home with A/C and it couldn't have come sooner. Thank you NexGen and team.

New to the neighborhood and called these guys, they were honest and helpful, quick and responsive and got the job done. Thank you so much!!!

My AC unit was making a strange noise. Felipe checked out my AC unit in a timely, professional, and helpful manner. Turns out nothing was wrong, it was just the water pump. He explained it to me and even waived the diagnostic fee. I will definitely be calling Felipe again!

Murphy's Law! Our A/C unit gave up the ghost right as the heat wave began. NexGen was the company that could get to me the earliest. The office confirmed I still needed service two days prior and on that day the tech, Justin, who works out of the Simi office arrived right on time. He was thorough, knowledgeable, and well spoken. Before he even left his Project Manager, Edson, called to discuss the situation. It's a relief to have a bright tech in your home to explain things clearly! Great service all around.

Really came through!
AC took a dive during a heatwave. Scheduled an appointment for next available window on a Saturday with NexGen for repair. Not only did they fix the issue, they also called me earlier in the week to let me know they had an tech (Alex) that could visit during an earlier window on Thursday. So helpful for my family during what was a pretty intense SoCal heatwave! Thank you NexGen

Felipe was so nice and thorough with all that he was doing, took his time to check it all out and was very informative. I am so happy I called. I previously had a negative experience with another company, but Felipe provided amazing service!
We will be using NexGen from now on.

The serviceman, Josh Perales, knew his job and we were quickly able to diagnose and repair our blower fan. He worked quickly and carefully to make the repair and get our AC back on-line. We definitely will use NexGen in the future!!

I was very satisfied with the replacement of my non-functioning HVAC system. They responded very quickly and completed the job in two days. The guys were courteous and explained anything I asked about. So glad I found NexGen.
