Cost To Run Window ACs Image containing a window air conditioner, dollars and text related to the question: How much does it cost to run a window air conditioner?

How much does it cost to run a window air conditioner?

It costs $0.06 to $0.36 per hour to run a window air conditioner, with the average being $0.xiii and the most common hourly cost being $0.ten.

This assumes a price per kWh of $0.fifteen (the US average) and as well assumes continuous maximum power describe.

Window air conditioners do not operate at their maximum wattage continuously, withal.

The amount of electricity window ACs depict reduces during dissimilar cooling stages, at unlike settings and at different room temperatures, among other factors.

The initial hour of operation tends to exist the most demanding in terms of electricity, and therefore price.

As a result, the figures summarized in the table beneath (and mentioned higher up) provide a good estimate of the cost to run a window air conditioner in the initial 60 minutes of functioning.

Window Air-conditioning running price category	Cost per hour (assuming continuous max power draw)
Average	$0.13
Nigh common	$0.ten
Highest	$0.36
Everyman	$0.06

Still, using this hourly cost to estimate how much information technology costs to run a window air conditioner for longer periods of fourth dimension will result in inflated figures.

The bodily ability consumption of window ACs should be used when estimating running costs for long durations.

When testing power consumption of window units and and then estimating annual energy usage, ENERGY STAR assumes 750 hours per year of compressor operation under typical conditions.

And so let's apply this authoritative source to get a more accurate idea of daily, monthly and almanac running toll of window air conditioners.

The table beneath lists how much it costs to run a window air conditioner per day, month and year, based on actual power consumption tests.

Window AC running cost category	Cost per day (based on power consumption tests)	Cost per calendar month / thirty days (based on power consumption tests)	Cost per year (based on power consumption tests)
Average	$0.31	$9.44	$114.82
Most mutual	$0.21	$6.16	$75.00
Highest	$1.xix	$35.57	$432.75
Lowest	$0.13	$3.82	$46.50

These results are based on the actual power consumption of i,037 window air conditioners and assume 750 hours per year of compressor operation under typical conditions, which is then averaged. The average price per kWh in the US (i.due east. $0.15) was also used.

Based on actual power consumption tests, window air conditioners toll:

Between $46.50 and $432.75 annually, with $114.82 existence the average and $75 being the almost mutual cost per twelvemonth;
Between $iii.82 and $35.57 monthly, with the average running price being $9.44 and the most common cost being $6.xvi per month; and
Between $0.xiii and $1.xix daily, with $0.31 existence the average and $0.21 being the well-nigh common running price per mean solar day.

These aggregated figures of almanac ability consumption estimates (using ENERGY STAR figures) provide a more than accurate running cost estimate.

Older, less efficient units volition autumn closer, and fifty-fifty higher up, the higher cost figures.

The hourly costs listed above are relatively loftier compared to these figures. This is considering these figures assume a more realistic estimate of power consumption and don't presume that the unit volition run continuously all 24-hour interval (the assumptions are listed above).

Interestingly, the everyman price per day to run a window AC is $0.thirteen, which is the aforementioned every bit the price to run an average window Air-conditioning per hour at its max wattage.

This demonstrates the importance of using an energy efficient and appropriately powered unit for your needs.

So which window air conditioner is the cheapest to run? Let'due south take a look at this adjacent, along with a more than detailed wait at the running costs.

Cheapest window air conditioner to run

The cheapest window air conditioner to run costs $0.13 per day, $three.82 per month, and $46.l per yr.

The Frigidaire – FFRE053WAE is the cheapest window Air conditioning to run – cheque it out on Amazon, here .

This energy efficient, low wattage window AC costs close to 58% less per day to run than average. Per month, this works out to $five.62 less in electricity, which is $68.32 less per yr.

Compared to higher wattage units, the toll savings in electricity are even more substantial (as much equally $386.25 less p/y).

Assumptions, including duration of utilize and kWh charge per unit, are the same equally above.

It costs only 6 cents per hour to run this unit, fifty-fifty at its maximum wattage of 400W.

Depression wattage window ACs are cheaper to run than their more than powerful counterparts. Simply this doesn't hateful they are as energy efficient.
