So how do you know which size air conditioner you need given the many different sizes available? It depends on the size of the room or rooms you are trying to cool. To start you need to measure the area that needs to be cooled and this will give you a good idea of the correct size air conditioner you will need. If you are looking for an air conditioner that will cool your entire house then please call us as there are many other factors needed to calculate this. To calculate the size you need to multiply the length times the width of the room or rooms you are trying to cool. When trying to cool two adjacent areas determine each space separately and add the totals together. Then refer to our chart to the right to see how many BTU’s your air conditioner needs in order to cool the room(s) properly. Example 1: You want to cool just one room that is 10′ long and 12′ wide. 10 X 12 = 120 By looking at our chart you would need an air conditioner with 5,000 BTU’s to cool this room of 120 sq. ft.

Example 2: You want to cool two adjacent rooms. Room #1 is 10′ long and 11′ feet and Room #2 is 8′ wide and 10′ long. Room #1: 10 X 11 = 110 Room #2: 8 X 10 = 80 Total of both rooms is 190. You would need an air conditioner with 6,000 BTU’s to cool these rooms. Once you have determined the number of BTUs that will most efficiently cool your rooms, you need to make adjustments based on other factors as well: How many BTUs to cool a room? Here are some common room sizes and the needed BTUs: 8 X 10 = 80 sq. ft. | 9 X 10 = 90 sq. ft. | 10 X 12 = 120 sq. ft. | 11 X 13 = 143 sq. ft. | 12 X 12 = 144 sq. ft. | 12 X 14 = 168 sq. ft. | 13 X 19 = 247 sq. ft. | 14 X 18 = 252 sq. ft. | 16 X 20 = 320 sq. ft. | While you can calculate the square footage on your own, one of our trained air conditioning professionals may be the better choice to perform a BTU calculation on your home. Give us a call and we will be more than happy to help you get the correct air conditioner you need.

Proper air flow into the air conditioner is essential for performance and safe operation. Under no circumstances should you block or cover any exterior or interior vents of the unit. How does the power cord work on my air conditioner? When should I test the plug? For your safety all Frigidaire air conditioners feature a 3-prong grounding plug and current leakage detection device. These enhanced plugs help to detect damages to the power cord and can be tested following a few simple steps. 1. Press the reset button 2. Plug the cord into the power outlet 3. Press the test button, the reset button should pop up 4. Press reset button for use 5. Do not use room air conditioner if above test fails. For more information please consult your use and care manual. What is the additional vent located under my air louvers?

On select models, you may notice a small tab identified with Open / Fresh Air / Closed. This fresh air vent allows the air conditioner to: 1. Recirculate inside air - Vent Closed 2.  Draw fresh air into the room - Fresh Air  3.  Expel indoor air outside - Vent Open. Note: When in the cool mode fresh air venting or exhaust venting will affect cooling and decrease performance. I have noticed water dripping outside of my room air conditioner, is this normal? Water dripping outside is a normal function of the room air conditioner, especially during periods of excessive humidity. If condensation need to be directed, window air conditioners have a key hole drain in the bottom of the unit where one could connect a ½” drain hose for safe disposal of excess system water.  Part: EA150D / 5304481680. Never drill holes into the bottom of the room air conditioner to remove water. If water is dripping inside the room during the cooling, this is due to improper installation.

Please refer to installation instructions or check with your local installer. I have noticed that my ENERGY STAR air conditioner is frequently in Econ mode? For all new ENERGY STAR products the EPA has regulated that all ENERGY STAR air conditioners must be factory set to Energy Saver (Econ) mode. If you turn the room air conditioner off in cool mode, and restart the unit it will default back into Energy Saver mode. You may select out of Energy Saver mode by selecting the mode button, however we recommend using the feature to help save energy. What is Econ mode? Econ mode, or Energy Saver mode, is a setting that works similar to central AC. The room air conditioner will turn off once the set temp is reached; the fan then cycles on (for 20 sec.) every 10 min to sample the air temp. If the room temp is above the set temp, the compressor will turn back on. Since the room air conditioner is not running at all times, this setting will help save energy while ensuring the room temperature stays at the set temperature.

It is a professional term rating an air conditioner. BTU stands for British Thermal Unit - the quantity of heat required to raise the temperature of one pound of water one degrees Fahrenheit. The higher the BTU the larger space the room air conditioner will cool. What size window unit do I need? The size of the window unit needed will depend on the size of the room you wish to cool. To determine which size you need, measure the width of the room by the length and multiply those numbers together to determine the square footage. What happens if I lose power? After a power outage, the unit will memorize the last setting and return the unit to the same setting once power is restored. What does Sleep Mode mean? When this mode is enabled, the selected temperature will increase by 2 °F 30 minutes after the mode is selected.  The temperature will then increase by another 2 °F after an additional 30 minutes.  This new temperature will be maintained for 7 hours before returning to the originally selected temperature. 

This ends the “Sleep” mode and the unit will continue to operate as originally programmed.  You may also cancel sleep mode at any time by again pressing the sleep button. Why is my room air conditioner making noise? Room Air Conditioners, during operation, may make noise.  It is normal to hear ‘high pitch chatter’ a sound of rushing air, gurgle/hiss, pinging or swishing and vibration.  These are all normal.  For more definition of noises, please refer to your product’s Use and Care guide. How do I store my room air conditioner for winter storage? If you plan to store the air conditioner during the winter, remove it carefully from the window according to the installation instructions.  Cover it with plastic or return it to its original carton.  NOTE:   To prevent rust or electrical connections from being damaged, store air conditioner in an upright position and a dry place. Why is my Filter Reset light on? This feature is a reminder to clean the Air Filter (refer to Care and Cleaning section of the Use and Care Guide) for more efficient operation.
