HVAC Services

We can install all types of HVAC units and provide service whether an A/C needs refrigerant or your furnace isn’t heating your home properly. Our team can fix heat pumps or clean an air duct while ensuring it is free of leakage. If poor insulation is affecting your home’s efficiency, we can add to or replace it so your home is effectively sealed. You can rely on Nexgen if your air conditioner breaks down or you’re looking at smart thermostats to upgrade an HVAC system. Also, you can count on us for maintenance that will improve both efficiency and the longevity of your air conditioning equipment.

Plumbing Services

We understand how urgent a plumbing problem can be. If your toilet is overflowing or you hear water but don’t know where it’s coming from, Nexgen can help. Our team performs leak detection to assess the condition of your piping as well as drain cleaning when necessary. Whether you need repiping or sewer repair, our techniques are less invasive than traditional methods. In fact, we can perform sewer cleaning from a remote access point as well as tree root removal and other sewer repair services. Technicians are dispatched no matter what time you call, so if you suspect a gas leak, our gas plumbing experts will come by and fix any issue with your gas line.

HVAC Units and Products

Nexgen offers the exclusive XBuilders, XComfort, XPrestige, and XDiamond Elite Series of:

  • Traditional Units: The ASX14 high-efficiency A/C includes an inline filter drier and self-diagnostics. We offer single-stage single- and multi-speed gas furnaces; a variable-speed A/C and the AMVM97 modulating variable-speed gas furnace are also available.
  • Electric Units: Our air handlers are designed with all-aluminum coils and for minimal air leakage. High-efficiency heat pumps, including the ASZ14/16, offer quiet performance; a two-stage heat pump and top-grade aluminum coil air handler are in stock as well.
  • Rooftop Units: Rooftop systems such as the APH14M packaged heat pump and APG14M gas electric pump take advantage of an all-aluminum evaporator coil and multi-speed ECM motor. Both are quiet and efficient. We also offer models with a variable-speed circulator motor.
  • Ductless Units: Single-zone heat pumps with 17 and 19 SEER energy ratings are available, while the 20 SEER Aurora heat pump achieves 100% heating and cooling capacity over an impressive temperature range.
