 Verdict / This slim in-wall AC unit has a lot of power, and it's packed with features that make it easy to use, including auto restart and a sleep mode. The FFTA1233Q1 is a great choice for a large room of up to 550 square feet.

There are many impressive wall air conditioners out there, but the Frigidaire FFTA1233Q1 still manages to stand out. It gives you full control over its many temperature, airflow and fan options, and the unit carries a variety of energy efficiency certifications. Also, its slim build makes it a good fit for most rooms. Because the FFTA1233Q1 has 12,000 Btu of cooling power, it can handle rooms up to 550 square feet.


This Frigidaire unit eclipsed its competitors because of how effectively it circulates air – up to 305 cubic feet per minute. That’s the highest airflow of the units we reviewed and means the FFTA1233Q1 can cool a room quickly. It has three fan speed options, so you can control the intensity of the air conditioner’s airflow. As such, you can control how comfortable the room is as well as save energy by setting the fan to use the least amount of power necessary to keep the air pleasant.

The unit has a high Energy Efficiency Ratio (EER) of 9.8. We reviewed several units with better EERs, including the Friedrich Uni-Fit US12D10C, but 9.8 is still impressive. One piece of proof is its Energy Star certification from the Department of Energy. Also, its estimated annual energy cost is $110. This number is based on using the unit eight hours a day over a three-month period – a standard measurement in the air conditioning industry.

This wall-mounted air conditioner can remove 3.3 pints of moisture from the air per hour, which helps make the room more comfortable if you live in a humid climate. It doesn't have a dehumidify-only mode, so if you want to remove moisture, you have to run the AC unit in a cooling mode. That’s usually fine since hot and humid weather tend to go together.


The FFTA1233Q1 has a programmable timer, so you can set it to turn on or off at specific times. For example, you can set it to turn on a little before you arrive home from work – the room will be comfortable right when you walk in, but you won't waste energy all day cooling an empty room.

If you don’t need to cool the room but want a breeze, you can use the unit’s fan-only mode. The device also has an auto-restart feature, so if there is a power outage, the air conditioner turns itself back on once power is restored. In addition, the unit’s sleep mode gradually increases the air temperature throughout the night. That way, you don't wake up to an overly chilly room or waste electricity. You can set the mode, temperature and fan speed via remote control from anywhere in the room.
