Welcome to NEXGEN
For 15 years, NEXGEN has grown from a single technician's vision into 10 locations serving homeowners across Los Angeles, Orange, Riverside, San Bernardino, and Ventura counties. Today, NEXGEN is a privately owned company under the leadership of owner John Akhoian. We're a licensed HVAC and plumbing contractor, California Contractor's State License Board #1011173, and we're proud to be a BBB Accredited Business.
Is NEXGEN a Reputable Business?
Yes. We hold an active California contractor's license (CSLB #1011173) and BBB accreditation, and we pull permits on every job that requires one, so the work is done to code and properly inspected. While we primarily serve homeowners, we've also worked with many of the region's larger contractors in Orange County, Los Angeles, and Ventura County, bringing that same level of expertise to every home we service. We back every job with competitive, transparent pricing and a price match guarantee: if you find a better price on a comparable quote, we'll match it. We also stand behind our work with a lifetime warranty on our own equipment line, so you're covered long after the technician leaves.
What We Do
NEXGEN keeps homes across Southern California comfortable, from AC and heating repairs to full system installs, plus plumbing work like drain clearing and water heater service. Whether it's a summer breakdown or a routine tune-up, our local teams in Los Angeles, Orange, Riverside, San Bernardino, and Ventura counties are ready to help.

Can't Say Enough Good Things
“My thermostat took a dive on me so I went to replace it. That's where I met Breanna at Home Depot she advised me on the Ecobee one and normally I don't use big companies because of cost is always higher since they have higher overhead. However, at $49 for a diagnostic they sent someone out and that's when things got even better Lazaro was our technician. He was trustworthy and communicative and effective at explaining to me and my wife what he's doing to our unit and why. In the end because of his demeanor and character I chose to get work done through his company. I got an ionizer placed and he patched a few areas where air was escaping. Cleaned condenser and added a second capacitor and cleaned the fan on inside of my house as well as checked the coils which were fine. In summary the company is trustworthy or at least my experience was good. At at a $49 diagnostic fee it was worth it to have someone come out and let me know where I'm at. Can't say enough though about Lazaro he sold me on trusting next gen so if everyone is like him you'll find value.”- S.S. -
Trustworthy Team
“My technician Joseph was a solid and upstanding dude. He took his time doing an inspection of my old hvac system. He let me hover over him and helped educate me on the different components of the furnace and AC units. He didn’t tell me what I wanted to hear, but he told me what I needed to hear. Would trust him and his team to do my maintenance and future installs for my home.”- Andrew W. -
Great Service!
“My AC stopped working and gave me a power failure message. Ryan was dispatched as the technician to assist. He was great, he quickly diagnosed the issues (fuses and capacitors). He gave me practical solutions and was great to work with. If I have issues in the future I will be asking for him specifically.”- Roger D. -
Appreciate the Team
“Gabe was so efficient and explained everything so we could understand. He took his time to thoroughly look at all of our concerns and figure out some type of solution. I appreciate his taking the time with us!”- Carly N. -
Went Above & Beyond
“Ryan was extremely professional and knowledgeable. He took the time to thoroughly explain everything in a clear, detailed way, which I genuinely appreciated. He was clean, respectful of our space, and very thorough in his work. You can tell he takes pride in what he does. He went above and beyond, and his kindness and professionalism did not go unnoticed. Highly recommend.”- Erika A.
