Description of the FFRE055S1 by Frigidaire

If you have a room of about 150 square feet, then this window-mounted Frigidaire’s 5000BTU FFRA0511R1 could help you quickly cool it effortlessly with its small but powerful air conditioner. I50 sq. Ft spaces include campers, trailers, and small bedrooms.

You only need to have the standard 115V outlet near this unit, and you can go on and enjoy your day in a cool breeze inside the house. It is also made to start with low voltage so as to save on energy. To add to this the efficiency has really been improved as it can cool effectively at an EER of 11.1. This is well above the Energy Star requirement of 10.0 EER.

Such efficiency pushes down costs of operating the appliance significantly to about $41 ( based on the national average electricity of 12 cents per kWh and seasonal use of about 8 hours per day over a 3 month period). You should, therefore, be able to save on costs while operating this unit.

Dehumidification is also modest, going at a rate of 1.1 pints per hour. This should ensure you keep the excess moisture controlled. There is also a filter with an antibacterial mesh that is accessible from the side by slide. This filter is able to remove harmful bacteria and dust particles from the air ensuring you have a comfortable experience.

The noise is kept considerably low during the operation and you should be able to sleep or study comfortably without being constantly woken up.

The control panel is very dependable as it features two mechanical rotary controls to manage the cooling and fan speeds. There is also an additional control knob that allows you to direct the air to the desired direction. One of the knobs, the thermostat dial, has a range of up to 7 different levels. You will have to settle manual temperature levels as opposed to a more accurate digital temperature display.

In case of a power outage, the unit is able to effortlessly restart and resume to previous settings.

This unit requires a window width of 23 – 36 inches to install easily. The extra-long, 6.5-feet, three-prong power cord makes extension cords unnecessary. You should refrain from using this unit alongside other appliances as it triggers circuit-breakers or breaks fuses.
