How much electricity does an air conditioner use?

On average, air conditioners use 500 to 4,000 watts of electricity. Actual energy usage depends on what kind of air conditioner you’re using.

How much energy does an AC use a year?

A large (or poorly insulated) house in Phoenix, for example, could use 12,340 kWh per year for air conditioning. On the other hand, an efficient apartment in San Francisco might only use 375 kWh (if it even uses central cooling at all). What about the amount of energy an AC uses at any given moment?

Does a building air conditioning system work at 100% capacity?

Realistically, no building air conditioning system operates at 100% capacity for the entire daily cooling cycle. Air conditioning loads peak in the afternoon -- generally from 2 to 4 PM -- when ambient temperatures are highest, which put an increased demand for cooling and electricity.

How much electricity does a window AC unit use?

An air conditioner uses significantly more electricity than a fan. A ceiling fan uses about 75 Watts of electricity per hour, while an average window AC unit uses about 1,000 Watts per hour. 2. Which uses more electricity, a window AC unit or central air? Central air uses about two thirds more energy per hour than a window unit uses.

How much electricity does a 5000 BTU AC use?

You can see from the chart that a 10,000 BTU AC uses 1.00 kWh, so anything smaller than 10,000 BTU will use less than 1.00 kWh. Example 3: How much electricity does a 5,000 BTU air conditioner use? A 5,000 BTU air conditioner uses 0.50 kWh per hour, and 360 kWh per month.

How many kWh does a 3-ton AC unit consume?

As you can see, this 3-ton AC unit will consume 16 kWh of electricity in 8 hours. Namely, every unit that runs on 2,000W will consume 2 kWh per hour. If you run it for 8 hours, that’s 16 kWh. This is just one example. It demonstrated how to calculate air conditioner kWh usage.
