Product Summary

The AMST air handler is AHRI certified and ETL listed. A DecaBDE-free thermoplastic pan is included, and also features secondary drain connections. The electric unit is designed to a depth of 21-inches, making attic access easier. It is also designed to reduce air leakage, which in accordance with ASHRAE standard 193 is:

  • Less than 2.0% at 1.0-in. H2O
  • Less than 1.4% at 0.5-in. H2O

The AMST’s all-aluminum coil features grooved tubing for efficient cooling and improved durability and comfort. A coil mounting track is designed to help reposition the unit quickly if necessary. The product’s factory-mounted expansion valves allow precise control of refrigerant flow, further improving efficiency, while the multi-speed blower motors help lower energy consumption and improve airflow. A SEER rating of up to 16 yields a great compromise between efficiency and cost.

An energy efficient solution, the HERS-tested unit is suited for heat pump applications that use an R-410 chlorine-free refrigerant. It is also R-22 compatible. This makes it ideal for adhering to the latest regulations and effectively delivering air heated by your furnace. And like other NexGen products, the AMST air handler features a 10-year lifetime warranty on parts and a Lifetime Unit Replacement Warranty, maximizing protection on your purchase.

This company cares for their customers. I had AC repair and the technician, Steve Arias, was very professional, kind, and very knowledgeable, not to mention handsome and well groomed. They followed up and made sure I was satisfied with my service. Also very easy to reach if I had questions or concerns. Great Service!!

Patrick truly came through for us in every way. Long story short, we were stuck in a 12-WEEK disaster with the home warranty company where we were without any A/C and no end in sight. One call to NexGen and Patrick showed up the next day with a clear, efficient, cost effective solution. He fixed it all within 24 hours.
