Product Summary

The ASZH4 electric heat pump is built into a heavy-gauge galvanized steel enclosure with a wire fan discharge grille, steel louver coil guard, and rust-resistance screws. A powder paint finish is baked-on for maximum protection against the elements. In addition to a compact footprint, the enclosure provides convenient top and side panel access for maintenance and single-panel access to controls; there’s also space to accommodate field-installed accessories. Bracket kits are available for anchoring the heat pump per the 2010 Florida Building Code.

Factory-installed components include a heater band and suction line accumulator to ensure reliable refrigerant distribution in extreme temperatures. An inline filter drier protects against dirt and moisture. The unit also has a sound control blanket and high-capacity muffler for quiet operation. It is optimized for efficient cooling with copper tubing and an aluminum fin condenser coil that uses R-410A refrigerant for maximum heat transfer. The ASZH4 has a SEER (Seasonal Energy Efficiency Rating) of 15 so the investment can lower HVAC system operating costs.

A 10-year limited warranty on parts is included. To obtain a lifetime warranty for replacement, become a member of the X Protection Family today.

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.
