Frigidaire – FFRE0533S1

Frigidaire has been in this business for quite a long time. This experience, coupled with extensive research gives them a wealth of information on virtually all kinds of possible customer needs and taste.

If you live in a small room such as a trailer camper or a small studio apartment, the noise level of your window appliance is of paramount importance as it could ruin or enhance your experience and sleep.

Frigidaire has got you covered with a small mini-compact powerful window air conditioner that is going to ensure your room is sufficiently cooled quietly with its 5,000BTU FFRE055S1 model. Let’s look at what it has to offer.

Description of the FFRE0533S1 by Frigidaire

If you have a room of about 150 square feet, then this window-mounted Frigidaire’s 5000BTU FFRE0533S1 could help you quickly cool it effortlessly with its small but powerful air conditioner. I50 sq. Ft spaces include campers, trailers, and small bedrooms.

This unit will work perfectly with outlets with the standard 115 voltages and still work as expected. 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 12.2. This is well above the Energy Star requirement of 10.0 EER.

The yearly cost of operating the appliance is significantly low at 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.

You don’t have to worry about keeping the unit on during the night as the noise is considerably subdued to about 50dB enabling you to sleep comfortably.

Unlike its FFRA0511R1 mechanical equivalent, this unit features a handy digital control panel to take care of those people who could have been turned off by the rotary controls in its bestseller counterpart. It has two fan modes and an additional auto fan mode that automatically chooses the speed of the fans. There is also a timer function to help those with busy schedules.

In case of a power outage, the unit effortlesslyΒ restarts 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.

The warranty only covers one year of operation on labor and parts.

Users' feedback

Users quotes on Amazon.comMan does this thing does its job. I've had it for about 6-7 months now and it can cool an 11x11 room in 15 mins. Noise isn't too bad but here's a more detailed note on this.. I sleep 3 feet away from this thing due to where my window is. Even if it's on all night, I can still sleep like a baby. However, I personally do need some sort of noise when I sleep. If you're someone who needs absolute silence, then this will be a problem."

Users quotes on Amazon.comSo far so good. The only thing we don't like is that when you turn off the AC and turn it back on, the default setting is for "econ" mode instead of the mode you last left it on. Small complaint. Overall it's been working great and isn't too noisy but provides the right amount of ambient noise to sleep in. We use it in our baby's room which is small but it cools off within minutes."
