Bottom Line

The Amana ASXC18 is not as efficient as most of our top-rated air conditioners, but sources say it's a good budget pick. It's fairly quiet and it's backed by an excellent warranty. However, depending on the configuration, this air conditioner may not be Energy Star qualified in all sizes.


  • Less expensive than other models
  • Reasonably quiet
  • Excellent warranty


  • Not all configurations are Energy Star qualified
Our Analysis

Breaking it down


Efficient – to a point. With a maximum SEER of 19, the Amana ASXC18 is reasonably efficient. However, depending on how it's configured, and the cooling capacity selected, some installations may not be Energy Star qualified. All Things HVAC says that it still could be a good choice for those in drier climates and where system demand is occasional rather than constant.


Two-stage compressor. While the Amana ASXC18 isn't a top-tier model, its lower efficiency allows for a lower price. However, that doesn't mean that it's completely devoid of extras. The editors at WebHVAC note that it uses a two-stage compressor, which provides for lower humidity, especially when matched with a variable-speed blower. ComfortNet is Amana's HVAC system that allows for components in the system to talk to each other to provide peak performance. The system works with ComfortNet or standard thermostats, but does not connect to the Internet or a smartphone app. It can alert users if a fault occurs, however, and stores diagnostic information to make troubleshooting easier. The noise level varies (71 to 74 decibels, depending on the unit's cooling power). The editors of Furnace Compare describe this as on "the quiet end" of central air conditioners, though some other models are notably better in this regard.

Maintenance and repair

A great warranty. The Amana brand is a mid-pack finisher in the latest Consumer Reports reader survey, with an estimated 18 percent of units needing service in the first five years. User feedback at Amana's site is better, 4.8 stars based on nearly 95 reviews. Keep in mind that many experts say that satisfaction and reliability are often more a function of the installer than of the HVAC equipment itself. Amana is confident enough in the ASXC18 to back it with a strong warranty. In addition to a 10-year limited warranty on parts, which is par for the course, Amana offers a lifetime limited warranty on the compressor. This means that if the compressor ever fails for the original purchaser, Amana will replace the entire condensing unit free of charge. However, owners must register their new air conditioners online within 60 days to validate the warranty; otherwise the coverage is for 5 years.
