Keystone KSTAT10-2C Air Conditioner Review

Cooling Performance

With effective BTU cooling power of 10,000, this unit will adequately service a living space of up to an estimated 450 sq. ft. On top of this, as an added bonus, this unit will remove approximately 2.3 pints of moisture per hour from the air of your home. We would recommend this in-wall AC unit for use in medium sized living spaces.

 

Efficiency / Certifications

With an Energy Efficiency Ratio (EER) of 10.6, its easy to see how this unit earned its Energy Star Qualification. This means that you as the user can be assured that this unit will not consume an excessive amount of energy. Thus, saving you hard earned money.

The Keystone KSTAT10-2C can also boast being UL-Listed. This means the appliance has been tested thoroughly by Underwriters Laboratories, the results of such concluding that this device does not have any negative effects on the air.

 

Convenience

On the topic of convenience, this device comes with several features in order to make user operation as easy and painless as possible. With a wireless remote control included, you won’t have to trek across the room to tweak the settings on this unit.

Further, the built-in 24-hour programmable timer means you can enter what hours you would like your unit to work. In response, this appliance will automatically power on and off in accordance with the timetable you program into it.

The Keystone KSTAT10-2C also has an Auto Restart function, whereby the unit will automatically reboot itself in the case of a power outage.

Other features include Fan Mode, Energy Saver Mode, and Sleep Mode. Fan allows the device to circulate air in the room without cooling it, for a refreshed, clear atmosphere. The Energy Saver functionality causes the unit to function at a reduced capacity, with the aim of saving you money, and consuming less energy. Finally, the Sleep function enables the device to slowly increase temperatures throughout the night, maintaining a comfortable environment while you sleep, saving you money, all the while at a lowered noise level.

Design

With an easily washable air filter, you needn’t fear inhaling large airborne particulates such as hair or dust. We recommend washing this filter monthly however, as if it gets too dirty, it will not function efficiently. This product’s 4-Way directional louvers allow for airflow to be directed at specific points in the room, which is an effective way of providing quick relief to very hot areas of the home.

Weighing 69.3lbs, the Keystone KSTAT10-2C is actually relatively light compared to other units of its type. However, we always advise our readers to seek aid, should the unit prove to be too heavy for them to lift, if they ever find themselves in such a situation.

Finally, with decibel rating of 58dBA, this unit is relatively quiet, with the average human conversation registering at about 60dB. This might be a bit tricky to deal with, however, if your unit is installed very nearby where you are holding a conversation.

 

Help & Support

Keystone’s customer support structure is unfortunately not as advanced as we would like it to be. With representatives only being contactable via email, and with virtually no other resources provided by Keystone, we find their customer service infrastructure to be severely lacking when compared with other brands we have reviewed.

Backed by a 1-year appliance warranty, and a 4-year compressor warranty, Keystone’s coverage is slightly below industry standard, as they only cover their compressors for4 years, one year less than the usual 5-year warranty. If you have any questions regarding warranty policies, we recommend that you contact Keystone directly.

 

Verdict

Overall, this is fine choice of in-wall air conditioner unit. However, there are issues. For one, we cannot help but be slightly suspicious when there is relatively little customer support being supplied by a manufacturer, and so we advise our readers to conduct some of their own research before blind-buying this product. Secondly, the lack of a dehumidifier mode and an auto mode is a shame, as these two modes are some of the core convenience enhancing features that we look for in units like this one. Putting this critiques to one side however, our final verdict stands, that this is a highly efficient unit, with a multitude of perks that not all units can boast having.
