Recommended Customer Reviews

I called NexGen to service my Gas Furnace. The technician by the name of Roger Cuadra came out and what a great person he was. He explained everything he was doing and what needed to be done. I felt no pressure. I'm a senior on a fixed income and he was so kind to wave the service charge. He deserves 10 stars

The NexGen team was fantastic! I was having issue with our heater and after doing a Yelp search, called a few places and immediately got a good vibe that mirrored the positive feedback I was reading in reviews. From that first phone call, the team was professional and organized. They asked me preliminary questions to understand the scope of services I needed, gave me an appointnment window, provided confrimation and even texted me with same-day updates on the status of their arrival which made me easily plan my day and not have to sit around and wait. Roger Cuadra, the technicain who came to diagnose was prepared and made sure he was communicating what he was doing every step of the way. He was open and honest from the onset, explaining a few options from best to worst case scenario to manage my expectation and I was thrilled when he ultimately was out of there in less than hour and was able to solve my issue with the tools and materials he had on hand. From beginning to end their services was top-notch. I had a great experience and I won''t hesitate to call again if I ever need their services in the future. 10/10.

The technician that came to my house was named Alphonso and he was terrific. He was thorough and efficient and I would certainly recommend him to my friends and family.

Thank you Dylan for coming over and helping me with my garbage disposal. He was efficient, on time and had great customer service. I will continue to use Nexgen because of my experience with Dylan! Thank you so much!!

I was charged $400+ after the technician reset my tankless water heater back in Nov. 2022 after it stopped running hot water.
3/28/23 update: I initially wrote a harsh review Zach, the owner, reached out and offered a partial refund. He was frank with me over the phone and I appreciated his effort to help make things right. At the end of the day, Next Gen was the only company that was able to fix the water heater that day and I was able to avoid replacing the entire unit.

Paulie helped us out with a stoppage that required a hydro-jet of our pipes. He was able to fix our issue with minimal downtime. He also took the time to go to Home Depot to pick up a repair part for our sink. Great experience and customer service.

Conner & Clemente came out to unclog the drain outside. Showed up on time, smelling good and eager to work and very professional. Troubleshoot our problem with a cool looking camera and finished up within 30 minutes. Great guys and great service at a good price. I highly recommend them and I will use them again in the future.

Okay.... guess I'll have to eat my words a bit. Bill Kean showed up to my house this morning with the super competent and professional Ullisses. Both worked incredibly hard to find the errors in the system installed and immediately fixed all problems and installed a simple thermostat that I could understand. Bill also offered me a generous compensation. Ullisses will be back tomorrow to install a new plate so that I don't have to figure out paint. I'm super happy and now feel confident in the installation. Thanks Guys!

Just had a great experience with Patrick Cordova at NexGen. He did a complete check of my heating unit. He constantly explained everything he was doing and then gave me a complete understanding of the issue. He explained all the options I have and was patient to allow me to make the best decision for my family.

Very convenient!
Low price with high quality!
scheduling online web quick. Got a call to confirm. Service tech showed up on time and knew exactly what to do. Best service in California.
