Product Summary

Delivering a cooling rating of up to 18.5 SEER and efficiency of up to 10 HSPF, the ASZC18 heat pump is energy efficient, quiet, and dependable with a lower operating cost that comparable equipment. Its Copeland two-stage scroll compressor uses chlorine-free R-410A refrigerant and includes overload protection. Peak cooling performance can be expected to last for years, as the compressor is designed with fewer moving parts than reciprocating compressors.

The HERS-tested heat pump is built for quiet operation. A sound control top on its heavy-gauge galvanized steel enclosure reduces noise, while a baked enamel finish protects the unit from the elements. A sound control blanket has been specially engineered to reduce noise levels from heat pump components, while a high-capacity muffler is also included. Thanks to time-delay SmartShift™ Technology, transitions to defrost mode are smooth and quiet. At the same time, indoor comfort is easily adapted with continuous monitoring provided by ComfortBridge Technology.

In addition, the ASZC18 is protected on many levels. A factory-installed bi-flow liquid line filter drier keeps dirt and moisture out of the refrigerant system, extending service life, while smart diagnostics constantly monitor performance. Copeland® ComfortAlert Diagnostics help find trouble spots quickly and reduce failures of electric or mechanical components. Furthermore, our standard warranty protection is expanded to a 10-year parts warranty and lifetime warranty on unit replacement when you join our X Protection Plan.

Operating the heat pump is simple when you connect it to Nest home automation systems. This allows you to control heating and other systems from your smartphone. It also provides instant notifications of problems and digital tools to act on them at any time.

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.
