Those rated as 14 000 can cover large rooms and even small apartments.
How much electricity does a small window ac use.
A good estimate for a medium sized window or wall air conditioning unit is 900 watts.
0 071 x 8 hours per day 0 57 per day 0 572 x 7 days per week 4 per week 4 x 4 weeks per month 16 per month.
Most smaller portable air conditioning units are powered around the 8 000 to 14 000 btu range.
Smallest window unit 500 watts.
The standard eer for most air conditioners is set at 10 0.
Largest window units 1440 watts medium window unit 900 watts.
If we take the average of running the device for eight hours per day and also consider the national kwh rate of 0 13 you can estimate spending the following amount per month on electricity for these different sized window air conditioners.
For test purposes i made power measurements using 2 typical products as examples.
A 5 000 btu small room budget ac unit the emerson quiet kool window air conditioner right.
The lower end of the spectrum 8 000 btu is enough for smaller single rooms.
Every air conditioner is going to use a certain number of watts per hour.
The lower two voltage ratings are common in smaller units while units with a rating higher than 15 000 btus will require a 220 volt circuit.
Eer is a measurement of how many btus the unit uses for each watt of power consumed.
How much does it cost to use a window ac for the average person.
Using these numbers you will be able to calculate how much using your air conditioner is going to cost you.
For example a 1000w ac unit spends 1 kilowatt hour of electricity per hour.
1500w unit for comparison spends 1 5 kwh of electricity per hour.
In other words it is a measurement of how efficient and how much energy your ac unit uses to cool the room.
An appliance s nameplate displays the amount of power it draws while running measured in watts.
The average central air conditioning unit will use somewhere between 3000 and 5000 watts of power every hour that it is in use.
Cost to run an ac your monthly power bill depends on local rates but there are a couple of ways to estimate your costs.
Most common voltage ratings for ac units are 115 125 and 220 volts and amperage rating can run from 15 to 20 amps.
If we assume that you run the unit for eight hours per day here s how much electricity it costs to operate a 550 watt window ac unit.
What affects how many watts an air conditioner uses.
High wattage air conditioners cost more to run.
A typical box fan used for cooling and white noise both are good choices as they re popular and fit the price range many people shop in.
