We’re the #1 HVAC company in Southern California for:

HVAC Services

Our technicians address any service need for traditional, electric, ductless, or rooftop HVAC units, whether it’s time for routine maintenance or you have an urgent problem. We service heat pumps and water heaters as well as provide new insulation and air duct cleaning and sealing.
The latest smart thermostats can be installed for additional convenience and efficiency. Nexgen will even perform electric panel upgrades before installing a new high-efficiency air conditioning or heating system. We are committed to ensuring our systems provide as much comfort and longevity as they are designed to.

Plumbing Services

Plumbing problems are often quite obvious, such as a slow drain, backed up toilet, or gas odor. Our technicians are skilled in performing drain cleaning and sewer cleaning if necessary (we even do hydro jetting). They can check for a gas leak and repair your gas line as well. Piping can be inspected with special cameras to isolate an issue to fix it or provide non-invasive repiping. If the issue is less obvious, we can employ advanced leak detection equipment to track down the problem. Sewer repair, replacement, and tree root removal can be completed without trenching your lawn.

HVAC Units and Products

  • Traditional Units: Our range of traditional heating and cooling systems includes the high-efficiency, quiet ASX14 air conditioner and advanced gas furnaces that range from a single-stage multi-speed model to a modulating variable-speed unit (AMVM97) that achieves a 97% AFUE and delivers continuous air circulation.
  • Electric Units: The ARUF heat pump accommodates cooling and heat pump applications thanks to a built-in check flowrator. Our popular line also includes the quiet ASZ14 heat pump and the AVPTC all-aluminum coil air handler that provides heating and cooling as well as auto configuration of airflow and tonnage.
  • Rooftop Units: Include packaged and gas electric heat pumps with a multi-speed ECM motor, single-stage scroll compressor, and heavy-gauge galvanized steel enclosure. Our APH16M and APG16M models integrate a variable-speed circulator motor for greater efficiency across their full range of operating capacities.
  • Ductless Units: We offer 17 and 19 SEER single-zone heat pumps that can be wall mounted. They provide air filtration and room coverage up to 1,600 square feet, like our other models. The Aurora, our top-of-the-line ductless high-efficiency model, offers up to 20 SEER and our widest heating and cooling range available.

X Protection Plan

Nexgen can tend to all your maintenance, repair, and installation needs with our X Protection Plan. For a small monthly fee, you’ll receive priority installation, discounts on repairs, and an annual air conditioner tune up, heater flush, and plumbing inspection. The plan also includes a dedicated phone line and guaranteed service window. We know that high costs often draw Tustin homeowners away from routine service, but our exclusive plan eliminates this concern from the equation.

X Protects Services

Our dedication to our customers isn’t limited to their comfort. Indoor air pollution can be many times more concentrated than outside pollutants. Nexgen installs the latest air purification systems and can protect your indoor air quality with HEPA filters and professional duct cleaning. If you’re concerned about security, we specialize in the Nest Secure system. Connected locks, alarms, and cameras can be controlled and monitored from your phone or other mobile device from anywhere.
