HVAC Services

Even in Southern California’s temperate climate, homeowners rely on their heating and cooling systems to stay comfortable. But every HVAC system will wear over time. Fortunately, our team can fix problems with all types of HVAC units and thermostats, especially if your home isn’t cooling evenly, the system is making noise, or it won’t turn on. Heat pumps can be repaired and we can maintain your furnace so it’s safe and reliable. Cleaning an air duct can dramatically improve efficiency and indoor air quality, while new insulation can minimize air leakage and keep your home cozy.

Plumbing Services

A toilet overflow, slow drain, or water backup can indicate a piping problem or an issue in your sewer line. If you hear running water but nothing’s on, there’s probably a leak. Our team specializes in leak detection methods that let us resolve issues fast. Whether a repair involves non-invasive repiping, sewer cleaning, or resolving a gas leak, NexGen is ready to serve Mission Viejo homes at a moment’s notice. Our gas plumbing experts can keep your home safe. We’re even experienced with tree root removal and preventing roots from encroaching on underground pipe again.

HVAC Units and Products

  • Traditional Units: We install and service high-efficiency air conditioners like the ASX14, up to the AVXC20 with inverter technology, a variable speed compressor and ECM condenser fan motor, and advanced diagnostics. Products also include an extremely efficient modulating variable-speed gas furnace unit.
  • Electric Units: Our energy efficient air handlers and heat pumps offer quiet operation, while delivering superior cooling capacity. The ARUF air handler is designed for easy attic access, minimizes cabinet air leakage, and is suited for cooling and heat pump applications. We also offer the AVPTC, an auto configurable air handler.
  • Rooftop Units: Featuring a durable all-aluminum evaporator coil, the APH14M packaged heat pump and APG14M gas electric model also use a multi-speed motor to improve efficiency. A variable-speed circulator motor further improves the reliability of the APH16M heat pump and APG16M gas electric system.
  • Ductless Units: Our wall-mount heat pumps with up to 17 and 19 SEER use a variable speed inverter compressor delivering up to 12.5 EER. The Aurora model provides up to 100% heating capacity at 5°F and peak cooling capacity at temperatures up to 104°F. All ductless models provide coverage of up to 1,600 square feet.

Amazing Reviews From Our Loved Clients

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.
Jack W.
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.
