The Frigidaire FFRA0511R1 model boasts several features for maximum practicality and convenience. The unit has two cool speeds, two fan speeds, and a two-way air direction. These features allow the user to adjust the temperature and air distribution as needed. Additionally, you will be able to sleep peacefully with this unit’s ability to operate smoothly and quietly. It’s low-power start-up saves energy and ensures quiet operation. The unit also comes with a washable mesh filter, a large power cord, and a window mounting kit for ultimate convenience. 


A quick-mount window mounting kit is included with the unit to ensure easy installation. The unit can fit windows with a minimum height of 13 inches and width of 23 to 36 inches. A standard 115V electrical outlet is sufficient to power the unit, and a 6.5-feet, three-prong power cord is included for additional convenience. For best results, keep other windows covered with curtains, blinds, or drapes during the day to keep out extra sunlight and heat. External sources of shade, such as trees or other plants, are another great way to maximize the unit’s cooling capabilities; however, additional sources of shade and cooling are not necessary for the unit to function and distribute cool air effectively. Simply installing the unit and adjusting the cooling and fan speeds according to your needs will produce the desired results.



The unit does require regular cleaning of its filter, an antibacterial mesh, to ensure it works as effectively as possible. It is recommended to check the filter at least once a month to see if it needs to be cleaned. This is extremely important to ensure that the filter removes harmful bacteria from the unit and cleans the air appropriately and effectively. The filter’s slide-out access makes it easy to take out and clean as needed. In addition to cleaning the filter regularly, be sure to keep the rest of the unit clean and dust-free to avoid fire hazards and prevent damage.


This AC unit is specifically designed to save energy while still providing effective cooling. A window-mounted AC unit is also a perfect choice for smaller living spaces because it does not take up additional floor or wall space. The window-mounting feature means one-time installation, making it a quick and easy process, and the two-way air direction function allows for optimal cooling distribution. Most users report that the unit operates excellently and meets their cooling needs. The easy installation process is another benefit many users find especially appealing about this unit.


This unit is not practical for spaces larger than 150 sq. ft., so if you are looking for a unit with a higher BTU and larger cooling capacity, check out some of the other Frigidaire products designed for larger living spaces. Or, look for similar models with a higher BTU designed for cooling larger spaces, such as the FFRA1022R1 that has a BTU of 10,000 and is designed to cool rooms up to 450 sq. ft., or the FFRH1222R2 that has a BTU of 12,000 and is designed to cool rooms up to 550 sq. ft. Some users also say that the unit’s long-term durability is not as desirable, but it works well for use during the summer when heat temperatures are at their highest.
