You can call NEXGEN and we’ll dispatch a crew to your home, and our technicians will diagnose the problem and fix it.

HVAC Services

Indoor comfort is important even in Southern California’s mild climate. Without maintenance, mechanical problems can remain hidden until your heating and cooling system breaks down. Repairs are often more expensive if you wait, but we can ensure all underlying issues are addressed before then. Replacing filters, refrigerant, and minor components in any HVAC unit enables it to work better and last longer. Air duct cleaning can maintain airflow and improve indoor air quality. NEXGEN can service any type of equipment. Whether you have a traditional unit or electric unit, or your property has ductless units or rooftop units installed, you can depend on our technicians. Heat pumps are another specialty of ours; our service technicians are experienced with absorption and air source pumps as well as ductless and geothermal units. Furnace damage can put home safety at risk, so it is important to call us if you notice cracks, pilot light issues, or noise from the unit. Insulation affects the reliability and efficiency of your HVAC system. It can degrade over time and may not be the most efficient based on modern standards. We can inspect your attic or wall insulation to determine whether more needs to be added or it should be completely replaced to improve efficiency, safety, and your overall comfort. And, we can help improve climate control at home with smart devices like programmable and Wi-Fi thermostats.

Plumbing Services

The smallest of plumbing leaks can lead to big problems. Water dripping behind your walls can cause hidden mold, while a burst pipe can cause substantial damage quickly and requires urgent attention. That’s why our team is available 24/7. If you’re not sure where the leak is, we can employ advanced leak detection techniques to get to the source of the problem without ripping out all your piping. We also employ safer and less invasive repiping methods to perform plumbing and sewer repair as well as tree root removal. Whether you have a slow drain that requires drain cleaning, or backed up sewage that requires sewer cleaning, our technicians are up to the task. We can also promptly address slow or running toilets, whether it requires cleaning a pipe, fixing tank parts, or replacing the unit. Diagnosing any problem is fast, since we at NEXGEN can find leaks using advanced equipment and even high-tech camera inspection systems to get inside your pipes to find hidden issues. Our technicians are also gas plumbing experts. If your gas stove or furnace isn’t working or you smell sulfur in the air, call us immediately and we’ll inspect your gas line for leaks and damage. If there’s a gas leak, it can be fixed right away to restore your gas service and safety. In addition, we can fix and install appliances such as hot water heaters and garbage disposals, so you can depend on us for any plumbing need.

  • 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.
