Amana ASZ18 18 SEER Heat Pump Rating


Amana products like the Amana ASZ18 18 SEER heat pump deliver very good quality, energy efficiency and a competitive price point.  This heat pump is energy-efficient for those who want to reduce energy consumption and utility bills.  It is built with quality parts that make it very dependable.  It’s no surprise that it does well across the board in heat pump ratings.

In this Amana ASZ18 18 SEER heat pump rating review, we grade this model in all the ways that matter, beginning with its energy efficiency.

Operating Cost Efficiency Rating [Rating:4/5]

The 18 SEER air conditioning and 9.5 HSPF heating are both Energy Star rated.  This model should produce a 35% to 50% drop in HVAC bills when it replaces a model 12-20 years old.  In moderate to warm climates, replacing a gas furnace split system with this heat pump and an air handler is also an option, especially where electricity is a good value or where utility companies are offering rebates for energy-efficient equipment.

Feature Rating [Rating:5/5]

The Amana ASZ18 18 SEER heat pump rating for features is a 5 because it offers everything you need for very comfortable home, and it has the versatility to be used in all climates.  Here’s an overview of the features that put it at the head of the class:

  • Copeland Ultra Tech scroll compressor is the top compressor in HVAC ratings.
  • 2-stage operation works with a variable-speed blower to optimize indoor comfort.
  • Duel fuel  capability makes this a good choice in warm and cold areas of the country.
  • Pressure switches offer maximum protection to the system.
  • Compressor blanket and other design features keep it running quiet.
  • Filter drier improves refrigerant performance and extends compressor life.
  • ComfortNet Communications coordinates system components.
  • R-410A refrigerant is more efficient and less damaging to the environment.


Reliability Rating [Rating:4/5]

The Amana ASZ18 heat pump demonstrates very good dependability and an excellent service record.  With proper maintenance, this is a 15-20 year heating and cooling solution.  The warranty proves Amana’s confidence in the reliability of this product.

Manufacturer's Warranty Rating [Rating:5/5]

This is one of the best warranties in the industry.  Amana backs the ASZ18 heat pump with a lifetime limited compressor warranty.  If it fails the original owner, Amana will replace the entire heat pump.  All other parts are covered by a 10-year warranty.

Overall Rating [Rating:4.5/5]

This is one of our highest-rated heat pumps.  The high efficiency cooling and the dual fuel heating makes it a top choice in climates with extreme temperatures.  For those in moderate climates, a more cost-efficient choice might be a 14-16 SEER heat pump that will cost less up front.  In moderate climates the high efficiency of this heat pump may not be required.

For reliability and outstanding performance, the Amana ASZ18 heat pump is one of the top handful on the market.
