HVAC Services

Even in Southern California’s temperate climate, homeowners rely on their furnace and heating system, as well as cooling, to stay comfortable. Maintaining your HVAC system is the key to ensuring it is reliable, efficient, and long-lasting. We can help do that and can fix any problem with traditional, rooftop, electric, and ductless units or heat pumps. We can provide a refrigerant recharge, component replacement, or air duct cleaning or sealing. Servicing your water heater is no trouble for our technicians and, if you need better insulation, we can manage that too. Our team can also fix, adjust, or replace thermostats as needed.

Plumbing Services

Emergency availability lets us resolve a water/gas leak, sewage backup, or burst pipe before major damage occurs. If there’s a blockage, we can perform drain cleaning using the most effective techniques. Our technicians can provide video camera inspection and other leak detection methods to find trouble spots in your piping, but for deeper trouble, we can do a sewer cleaning via fast and simple methods. Even if you need sewer repair or tree root removal, we can complete the job without any digging. We use the latest repiping techniques to restore pipe from the inside out. And, if there’s an issue with your gas line, our gas plumbing technicians can quickly restore your safety.

HVAC Units and Products

At Nexgen, we offer the XBuilders, XComfort, XPrestige, and XDiamond Elite Series of HVAC systems. Representing some of the best equipment in the industry, these include:

  • Traditional Units: Quiet, high-efficiency air conditioners are available, but you can level up to a super-efficient variable-speed A/C (AVXC20). Our gas furnaces include a single-stage single-speed/multi-speed models and a modulating variable-speed gas furnace (AMVM97).
  • Electric Units: The ARUF air handler is built for efficiency and easy attic access, while the quiet ASZ14 heat pump has a pre-installed inline filter drier. We also offer an all-aluminum coil air handler and two-stage heat pump designed to reduce electricity consumption.
  • Rooftop Units: The APG14M gas electric heat pump and the APH14M packaged system provide the efficiency of a multi-speed ECM motor and durability of an all-aluminum evaporator coil. We also offer a heat pump and gas electric unit with a built-in variable-speed circulator motor.
  • Ductless Units: Variable speed compressors contribute to efficiency and reliable performance, which you can depend on the 17/19 Series Wall Mount single-zone heat pumps for. Our Aurora heat pump delivers an outstanding 20 SEER efficiency rating.

X Protection Plan

Nexgen is committed to providing members of our X Protection Plan with priority service. We can ensure your equipment is working and gets the care it needs through a free annual tune-up (for A/C’s and heaters), water heater flush, attic/crawl space efficiency/safety analysis, and whole house plumbing inspection. Priority installation is available for new or replacement systems. You’ll even get discounts on future repairs and indoor air quality systems. Plus, our plan is transferrable for when you move or rent out your home; it also comes with an extended warranty covering parts and labor.

X Protects Services

Our contractors aim to provide the highest quality service possible, which includes maximizing your safety and security. In addition to the most reliable and efficient equipment on the market, we can help improve indoor air quality to exceptional standards. Indoor air pollutants can be many times more concentrated than outdoors, which can be resolved through air duct cleaning, HEPA filters, and advanced air purification systems. We also install smart door locks, alarms, and complete home surveillance systems to keep you protected, and are committed to your overall comfort, privacy, and safety.
