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 (though still louder than some) and it's backed by an excellent warranty. On the down side, this air conditioner may not qualify for an Energy Star tax rebate, and Amana's reliability record is less than stellar.


Efficient – to a point. The chief measure of a central air conditioner's efficiency is its seasonal energy efficiency ratio, or (SEER). This is a measure of its cooling output over an entire season divided by its energy use for the same period. Most sources, including the product brochure, say the Amana ASXC18 can reach a SEER of "up to 18." However, depending on how it's configured, the unit's SEER may actually range from 15 to 19. Likewise, the energy efficiency ratio (EER), a measure of its efficiency at a given point in time, can vary from 11.2 to 13.25. So it may not qualify for an Energy Star rating, which requires a SEER of at least 14 and an EER of at least 12.

The noise level also varies (71 to 74 decibels, depending on the unit's cooling power). The editors of describe this as "particularly quiet." However, we did find other air conditioners in our sources that are quieter.

Pricing and rebates

A budget pick. Since Amana, like other manufacturers of central air conditioners, doesn't make its prices public, we turned to two contractor-run sites for price estimates. provides wholesale prices for the ASXC18 ranging from about $2,550 for the 3-ton unit to about $3,300 for the 5-ton version. This is roughly in line with the average prices reported at, which range from $2,399 to $3,139.

These prices make the Amana ASXC18 significantly less expensive than most of our favorite central air conditioners. However, because it's less efficient than others, the ASXC18 may not qualify for government and utility company rebates, including a $300 federal tax credit offered through 2013.

Maintenance and repair

Iffy reliability, but great warranty. Amana air conditioners as a whole are not as reliable as many other brands. A survey of more than 40,000 homeowners with central air conditioning systems shows that 17 percent of Amana units needed repairs during a five-year period, compared with 11 to 13 percent for most brands. Reviews at are split between positive and negative, with complaints mostly based on durability. However, positive reviews often point out that problems with central air conditioning are likely due to poor installation rather than faulty equipment.

One strong point of the ASXC18 is its warranty. In addition to a 10-year limited warranty on parts, which is par for the course, Amana offers a lifetime limited warranty. 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.
