What every best Central Air Conditioners has:
- High efficiency.
- Good value.
- A solid warranty.
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, and it's among the least expensive central air conditioners we cover. However, that doesn't mean that it's completely devoid of extras. The editors at WebHVAC.com 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 FurnaceCompare.com describe this as on "the quiet end" of central air conditioners, though some other models are notably better in this regard.
A great warranty. The Amana brand is a mid-pack finisher in the latest ConsumerReports.org reader survey, with roughly 18 percent of units needing service in the first five years. User feedback at Amana's site is better still, 4.8 stars based on 60 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. Owners must register their new air conditioners online within 60 days to validate the warranty; otherwise the coverage is for 5 years.
The Amana ASXC18 receives an in-depth review here. Editors rate the reliability at 4 out of 5 stars, and note that it gets good ratings from those that have installed the unit. They add that this Amana central air system offers "an attractive combination of high efficiency, excellent performance and one of the best warranties in the industry." Overall, the editors grant the system a rating of 4.5 stars.
Here, the ASXC18 earns honorable mention status. Efficiency and features trail higher rated central air conditioner systems, but the Amana costs less and is a "viable choice for those who only need to use the AC from time to time".
User reviews of central air-conditioner systems are hard to come by, but we found roughly 60 at the manufacturer's site for the Amana ASXC18. It earns an overall rating of 4.8 stars out of 5. Reviews are authenticated by a third party service, which adds to their veracity.
FurnaceCompare.com is most valuable as a source of owner reviews of central air systems, but here editors also give their take on the Amana ASXC18. Information is offered on efficiency, noise level and the ComfortNet control and communication system. A few owners also weigh in.
ConsumerReports.org does not test central air conditioners, but it does evaluate the reliability of some of the most popular brands, including Amana. The most recent survey is based on responses from more than 14,000 readers who purchased systems from 2009 through 2016.
