Nexgen is the leading HVAC/plumbing contractor in Fontana and Southern California.

We can reach homes quickly in an emergency and can perform any type of repair. Customers rely on Nexgen for installation, replacement, and maintenance of existing systems and the latest, most efficient air conditioners, heat pumps, and furnaces as well as prompt and effective plumbing service.

We are a professional contractor capable of reaching your home quickly. If you suspect a water leak or your A/C fails, there’s no reason to wait. You can call Nexgen and we’ll dispatch a crew to your home, and our technicians will diagnose the problem and fix it. We address drain and toilet problems, sewer issues, and any type of mechanical defect in your heating or cooling system. Live operators are available to help schedule a visit or send technicians in an urgent situation. We also offer free estimates, competitive pricing, and affordable financing options.

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.
