Installation & Replacement

An air conditioning, cooling, or heating system can operate efficiently only if it is installed correctly. We can ensure it is properly connected and sized for your facility, so it is safe, efficient, reliable. Nexgen installs ductless split systems, central air conditioning units, and package/rooftop units as well as various types of equipment. Our technicians can install a thermostat or provide additional insulation. If the reduced performance of an aging and/or failing AC system is affecting indoor comfort, it is time for replacement. But there are many reasons to consider replacing an HVAC system long before it fails. It can:
  • Reduce Maintenance Costs: You won’t require as many repairs or need to find outdated, and more expensive, original parts.
  • Boost Energy Efficiency. Modern systems use less electricity to provide the same heating/cooling power, so they can lower your company’s utility bills.
  • Remove Contaminants: Dust, pollen, viruses, and other pollutants are more effectively removed, improving indoor air quality and the well-being of employees and customers.


Nexgen is a full-service HVAC repair company and can fix all types of HVAC units. Our technicians can get your air conditioning system working again whether there’s a leak or drainage problem, broken compressor, or damaged condenser coils. If there isn’t enough cold air in your office or retail location, we can determine the cause and fix it. A duct leak can be repaired to restore your system’s performance and efficiency, as our team is experienced in duct repair and replacement. Insufficient heating and cooling are sometimes caused by a faulty thermostat or sensor, but we provide the necessary repairs to restore the function of your system. We can quickly diagnose common problems such as lack of temperature control or an air conditioner not turning on. Electrical control and connections failure, limited airflow, and stale air are other problems that can be addressed by our technicians. Corrosion on an electrical connection can negatively impact performance, but we can replace affected parts to resolve the problem.

Maintenance Service & Plans

Routine maintenance enables your commercial HVAC system to run at peak efficiency. It can help avoid unforeseen problems and mitigate minor issues that can ultimately lead to system failure and expensive repairs. Maintenance means fewer repairs, longer system lifespan, and improved indoor air quality. At Nexgen, we offer an exclusive maintenance plan that includes system tune-ups, indoor air quality testing, and checking refrigerants to determine whether a recharge is needed, among various other services. Our X Protection Plan guarantees you priority service and savings on important maintenance and repair work, with both short-term and long-term benefits. Best of all, it can be customized to the needs of your facility. We can prevent commercial or industrial air conditioning system malfunctions that can be highly disruptive to business. Familiar with the maintenance needs of leading HVAC systems and commercial customers in Southern California, we provide service at regular intervals to ensure no issue goes unchecked. Preventative maintenance allows us to fix minor problems before they are noticeable.

Not only did his team deliver promptly and on time, they were friendly and left with a professional install of my new A/C unit. I can’t mention the AWESOME price I got, but needless to say they can beat any deal, and will give you the fastest 1st-rate service available.

Yesterday I had Nexgen install a new furnace and a/c system to replace my 30-year-old system. Their representative Jeff met with me the day before to go over the system that would work best for my home, and presented me with a price I couldn’t turn down. Incidentally, Nexgen’s price was over $3,000 cheaper than all other competitors.

My call was promptly returned by Jeff and an appointment was scheduled for the next day. Jeff presented an offer that I couldn’t refuse! A crew was available that day and came, saw and conquered. I had A/C that evening at a very fair price. Highly recommend Nexgen.
