Customer Reviews

Paul McPherson

My AC unit went on the fritz during a recent heatwave and Nex Gen was available almost immediately to help! Their customer service was outstanding in a world where quality customer service is a rarity and most often a huge disappoint!! Alondra was kind, courteous, and very helpful when making the appointment! She did an outstanding job by clearly communicating the timeline and all updates on the days events. The service technician, Juan, was simply wonderful!! He was kind, courteous, clean, and extremely knowledgeable about his job! He clearly explained what the issue was and exactly what he was going to do about it. He worked in a timely manner and was just the nicest guy in the world! I would highly recommend Nex Gen and in all honesty would give them 15 out of 10 stars!!! Thanks again, Juan!!! Keep up the great work!!!??

The HVAC technicians were friendly and provided full explanations of the issues with my system including photos. They clearly explained the options or help in deciding how to move forward. They completed the installation quickly and cleaned up the workspaces when done. One of their plumbers also provided quick maintenance on my instant hot water heater. Highly recommend this company.

I had a great experience with Jose Benjamin Frias from Next Gen Systems. He performed maintenance on my unit, cleaned out my attic area, and added an ionizer to my system. He was professional, punctual, and very knowledgeable. He took the time to explain everything clearly and made sure my system was running efficiently before leaving. I truly appreciate the quality work and attention to detail. Highly recommend Jose and Next Gen HVAC Systems for their excellent service!

Our Tech Juan J was great. I had issue with furnace and he diagnosed the issues fast. He replaced the new part we needed and most importantly he worked with our busy schedule. Very professional, NexGen is in good hands.

Carlos Jimenez

Ryan from Nexgen AC did an excellent job from start to finish. He arrived on time, was very professional, and clearly knows his trade. He took the time to properly diagnose the issue instead of jumping to conclusions, and he explained what he was checking and why at each step of the process. Ryan walked me through the system operation, the electrical readings, and how the components interact, which I really appreciated. He made sure everything was operating within spec, verified voltages and controls, and confirmed proper system response before wrapping up. He also kept the work area clean and organized and made sure nothing was left behind. What really stood out was his attention to detail and willingness to explain things in a way that actually made sense. I never felt rushed or in the dark about what was being done. If you’re looking for a technician who is knowledgeable, thorough, and takes pride in his work, I highly recommend Ryan at Nexgen AC.
