Goodman DSXC18 Review

Author by

PROS / The Goodman DSXC18 uses a refrigerant that is chlorine-free and is formulated to protect the ozone layer.

CONS / The SEER rating is comparatively low.

 VERDICT / Other products are slightly more efficient, but a lifetime warranty helps Goodman DSXC18 stand out in a good way.

The Goodman DSXC18 central air conditioner is available in three different capacities, has a lifetime warranty and a durable design, and is quiet enough that it will not bother you or your neighbors. It does not quite make the top rankings because it is not as energy efficient as some competitors. It is still likely to save you on future electrical bills if you are replacing an outdated model, though.

This AC unit has met all the Energy Star guidelines, established by the Environmental Protection Agency to reward manufacturers that conserve energy. It also features up to 18 SEER (seasonal energy efficiency ratio) performance. At this rating, the unit is excellent when it comes to energy efficiency, but the very best central air conditioners have even higher SEER ratings.

This air conditioning system uses environmentally friendly R-410A refrigerant. This refrigerant is chlorine-free and is formulated to protect the ozone layer. This central air conditioner also features a two-stage scroll compressor that is specifically designed to have fewer moving parts. The means less energy consumption.

A high-density foam compressor sound blanket is available to help reduce the sound from this unit. But overall, you won't be bothered by this quiet air conditioner. Its sound output is 71 decibels. This is fairly quiet for this type of device, although it is worth noting that it is not the quietest of the home AC units we considered.

Upkeep should be pretty simple with this unit. The onboard diagnostics allow you to store up to six fault codes so you will always know when there is a problem developing. You will also have multiple access points that will simplify repairs and annual upkeep.

One of the standout features of this central air conditioning system is its excellent warranty. The Goodman DSXC18 features a lifetime warranty. If it fails and you are the original purchaser of the air conditioning system, you will receive a new unit as long as you live in the same residence. All parts on the device are covered by a 10-year parts warranty, which is also an excellent benefit.


The Goodman DSXC18 is an energy-efficient product that can help save you money over older generations of air conditioners, however, it is not quite as impressively-efficient as our top-ranking products. It has the fifth-highest SEER rating in our comparison but this air conditioning system is built to be durable and efficient, with environmentally friendly R-410A refrigerant and a lifetime warranty to ensure it will provide a comfortable indoor environment for many summers to come.
