    Went Above & Beyond
    “Ryan was extremely professional and knowledgeable. He took the time to thoroughly explain everything in a clear, detailed way, which I genuinely appreciated. He was clean, respectful of our space, and very thorough in his work. You can tell he takes pride in what he does. He went above and beyond, and his kindness and professionalism did not go unnoticed. Highly recommend.”

    Excellent Team

    Can't Say Enough Good Things
    “My thermostat took a dive on me so I went to replace it. That's where I met Breanna at Home Depot she advised me on the Ecobee one and normally I don't use big companies because of cost is always higher since they have higher overhead. However, at $49 for a diagnostic they sent someone out and that's when things got even better Lazaro was our technician. He was trustworthy and communicative and effective at explaining to me and my wife what he's doing to our unit and why. In the end because of his demeanor and character I chose to get work done through his company. I got an ionizer placed and he patched a few areas where air was escaping. Cleaned condenser and added a second capacitor and cleaned the fan on inside of my house as well as checked the coils which were fine. In summary the company is trustworthy or at least my experience was good. At at a $49 diagnostic fee it was worth it to have someone come out and let me know where I'm at. Can't say enough though about Lazaro he sold me on trusting next gen so if everyone is like him you'll find value.”

    Appreciate the Team
    “Gabe was so efficient and explained everything so we could understand. He took his time to thoroughly look at all of our concerns and figure out some type of solution. I appreciate his taking the time with us!”
    - Carly N.
    Trustworthy Team
    “My technician Joseph was a solid and upstanding dude. He took his time doing an inspection of my old hvac system. He let me hover over him and helped educate me on the different components of the furnace and AC units. He didn’t tell me what I wanted to hear, but he told me what I needed to hear. Would trust him and his team to do my maintenance and future installs for my home.”
    - Andrew W.
    Great Service!
    “My AC stopped working and gave me a power failure message. Ryan was dispatched as the technician to assist. He was great, he quickly diagnosed the issues (fuses and capacitors). He gave me practical solutions and was great to work with. If I have issues in the future I will be asking for him specifically.”

Traditional Heating & Cooling

Traditional Heating & Cooling

The XDiamond Elite air conditioner from NEXGEN represents the superior efficiency and comfort control of the AVXC20. Delivering up to 24.5 SEER, it includes a high-efficiency variable speed swing and scroll compressor and variable speed ECM condenser fan motor. Adaptability to high loads is enabled by the system’s field-selectable boost mode, which increases compressor speed to match demand.

A durable compressor demonstrates the latest compression technology and includes overload protection. Complimented by a high-efficiency condensing coil, featuring corrugated aluminum fins and refrigeration-grade copper tubing, it’s engineered for years of reliable performance. A bi-flow filter drier is installed in the field. Coil and ambient temperature sensors further improve performance as does a control system that relies on algorithmic logic.

Additional features that contribute to the XDiamond Elite include:

  • ComfortNet Communication: Temperature settings, scheduling, and performance monitoring can be managed via a touch-screen LCD, which also delivers automated maintenance alerts.
  • Acoustical Control: A high-density foam sound-reduction cover tops the compressor while a grille-style sound control top is fit on top of the heavy-gauge, galvanized steel cabinet
  • Comfort Speed Inverter Technology: The compressor and fan motor can run at 100% on hot days, but variable speed technology allows a reduction in capacity during milder days, thanks to an advanced energy management system.

A highly efficient design maximizes cooling capacity. The XDiamond Elite uses the latest R-410A refrigerant that meets the latest industry standards. Heat transfer is optimized via the use of an aluminum fin condenser coil and a five-millimeter refrigerant-grade premium copper tubing system. Power and speed levels are automatically adjusted as the inverter system calculates the lowest amount of energy needed to maintain the set temperature.

The unit’s heavy-duty enclosure not only offers sound-dampening properties. It is also a 500-hour salt spray tested and treated with a baked-on powder-paint finish for maximum durability. In addition to a steel louver coil guard and wire fan discharge grille, the unit provides single-panel access to controls and top and side access points for maintenance, so servicing and caring for your system is simple.
