12,000 btu emerson quiet kool 220/230 about 9 years old, need to know $$ per hour to run with total kw/h cost $0.30 (this includes all taxes and fees). Sorry can't provide wattage or amps (no manual and front panel is being very stubborn-don't want to damage in removal).Thank you for your assistance. Henry

I found this I hope it helps.

Performance BTU/H Cooling: EER: Voltage: Amps: Watts: Cooling Area (Sq. Ft.): Pints/Hour: Room Air Delivery (CFM): Plug Cap Amps: Plug Type: Dimensions Width: Depth: Height: Net Weight: Shipping Weight: http://www.appliancefactoryparts.com/airconditioners/emerson/12ht13.html#Manuals

the total power used is 750 watts so multiply that by the number of hours in use say 60 hours a week
so 60 X 750 = 42000 or 4.2 kw hours X 4 cents per kw/h =418 cents or $4.18 per week X 4 weeks =$16.72
if you are a college student talk with a maths teacher and see if what I an calculating is correct but there is no way that the ac unit will cost $150.00 a month to run
you have to be careful here as to charge you for an ac unit , it has to be on a separate meter and I suspect that he is trying to get you to subsidise his electricity account outside of the rent costs which include power for the stove and hot water
as an example we run a 2.7kw ac for 12 hours or longer and the total household bill at 21 cents / kw hour ( we live in a country where the power is a major component of the household budget) is around $360.00 per month so I think that by comparison he is trying to rip you off
seek legal advice on the subject and if the rent payment includes electricity usage then he will need a separate meter to charge for the ac unit

I know that a Island Air units come in all shapes and sizes and they make a ton of different units. They are made in new york thats who I would use. I would definitly go with the 12,000 btu unit 500 square feet needs 12,000 btus 10,000 is under sized. 500 square feet divided by 500 = 1 ton of cooling. let me know if I can further assist.

To determine the cost of using this air conditioner, you will need to find out what your electric company charges per kw/h. This is the standard unit that electricity is charged for. Next determine the wattage of the air conditioner. This should be found on the unit name plate. If you can not find the wattage by the name plate, the take the voltage and multiply by the amperage, this will give you watts. Next multiply the wattage by 24. (watts per hour x 24 hours) Finally divide this number by 1000. This will give you the total Kw that the unit will use in a 24 hour period. If you multiply this number by the cost per Kw that will give you the operating cost of your unit for one day.
ex. electric company charges .25/Kw The unit uses 1000 watts 1000 x 24 = 24000 watts 24000/1000 = 24 Kw 24 Kw x .25/Kw = $6.00 day
Note: all figures shown above were randomly generated in my head, and have no correlation to your calculations. Hope this helps.

Air conditioner equipment power in the U.S. is often described in terms of "tons of refrigeration." A "ton of refrigeration" is defined as the cooling power of one short ton (2000 pounds or 907 kilograms) of ice melting in a 24-hour period. This is equal to 12,000 BTU per hour, or 3517 watts.[13] Residential central air systems are usually from 1 to 5 tons (3 to 20 kilowatts (kW)) in capacity. To determine the correct size keep in mind that 12,000 BTU's equals 1-ton. Use the table below to determine the size AC that you need. Hope this helps. Area To Be Cooled (square feet) Capacity Needed (BTUs per hour) 100 to 150 5,000 150 to 250 6,000 250 to 300 7,000 300 to 350 8,000 350 to 400 9,000 400 to 450 10,000 450 to 550 12,000 550 to 700 14,000 700 to 1,000 18,000 1,000 to 1,200 21,000 1,200 to 1,400 23,000 1,400 to 1,500 24,000 1,500 to 2,000 30,000 2,000 to 2,500 34,000

The internal motor mounts for the compressor are broken, that is the loud banging.
At 17, new one is more energy efficent.

If you know where to find a filter for a Emerson Quiet Kool--Model # 18DD4H-EE
