How Much Does an Air-conditioning Price Per Month

Days are again growing longer and hotter and the temptation to leave your air conditioner on all mean solar day is high. When summer days scroll effectually, you tin can wait the energy bills to spike as the sugariness relief provided by your AC unit of measurement comes with a price.

It'southward hard to put a price on comfort, but if you are watching your spending, y'all might want to estimate how much your heating and cooling costs you per month & try some clever tricks to reduce the electricity cost of air conditioner.

How Much Does it Cost to Run an Air Conditioner

Before nosotros start computing the air conditioner price, we should practice a quick overview of the energy units that nosotros will exist using.

BTUs – A BTU stands for British Thermal Unit. It is used to measure out the amount of energy that is required for your air conditioner to cool one pound of water by ane degree Fahrenheit. Your air conditioner might have this number expressed in tons (on the energy label). One ton equals 12,000 BTUs per 60 minutes. The term one ton comes from how much heat is required to cook a block of water ice that weighs one ton.
Ampere – Amperage, or AMP, is a measure of how much electricity is flowing through an electric circuit per unit of fourth dimension.
Watt – A Watt (W) is another unit of power, and is defined every bit ane Joule of energy per 2d. Since watt is actually very small, we can convert one thousand watts to a kilowatt (kWh)
Kilowatt Hr – Kilowatt-hours measure the number of kilowatts used past an appliance in the duration of one hour.
Volt – A Volt is a mensurate of the electric potential between two points on a wire. In the United States, the standard power outlet voltage is 120 V.

If yous are however confused, we don't blame y'all. Electricity is a hard concept to grasp because we can't run into it. Let's instead borrow an analogy that we all can relate to more easily – a flow of water. The rate at which the h2o flows is measured as a current (in Amperes). As the h2o flows through a pipe, it creates pressure against the pipe, which would exist the voltage (measured in volts). And wattage is the amount of h2o (power) is released each second (measured in watts).

Navigating energy conversions can go a long way towards a ameliorate understanding of your utility bills and ultimately – being able to reduce them. If you are curious about other energy units and how to estimate your monthly electric nib, you lot can read our simple guide to help you primary the nuts.

But back to air conditioners…

AC Toll Factors

Now that the understand the free energy conversions involved, we can keep with our estimation of how much does it price to run an air conditioner for a period of time. At that place are different factors that will impact your air conditioning electricity toll:

Formula For Determining Air conditioning Costs To Operate

So now that we have all the ingredients, we tin finally calculate how much does ac cost per month. Still, keep in heed that the below calculations are based on many assumptions and should be used solely equally guidance.

Step 1: Allow's beginning by assuming that y'all have a standard 4-Ton Air Conditioner (Read where to find the tonnage of your unit here). Next, calculate how many amps does your unit of measurement draw:

ii-Ton Air Conditioner – fifteen amps
3-Ton Air Conditioner – 18 amps
iv-Ton Air Conditioner – 21 amps

Step 2: Remember, amperes point the rate at which the water flows (in our earlier analogy). The next step is to determine the corporeality of water itself – wattage. To effigy this out, merely multiply the amperage from step i by the voltage of your outlet – let's assume it'south a standard 220V.

21 amps ten 220 V = 4620 watts or four.62 kilowatts. What does that mean? If y'all let your air conditioner run for i hour, it will burn four.62 kilowatts of energy.

Step three: The final step in calculating your ac costs is multiplying the iv.62 kilowatts by however many hours volition your Air-conditioning exist running. If maths isn't your thing, don't worry. The Washington State University'south Energy Program offers a costless air conditioning running costs calculator on their website.

One last thing – Your price per kWh will profoundly affect your AC system cost to run. For case, if yous live in Texas and yous oasis't even so switched energy suppliers, y'all are probably paying the standard energy tariff of 11.85 cents per kWh. However, a quick look at offers from other providers returns several long term contracts with rates between 5.99 and 10 cents. With an average household usage of approximately 1000 kilowatts a month, this can make a huge difference to your utility bills.

Price to Run Air conditioning

Now, let'due south add up the number of hours per twenty-four hours usage to get the total estimate of your electricity cost for air conditioner in your monthly utility beak.

Toll To Run AC For An 60 minutes – From the earlier department, we know that your Air conditioning arrangement uses iv.62 kilowatt-hours of free energy (based on approximate figures!). Multiply this number by your rate per kWh to get the bodily cost of one hour's use of your HVAC unit of measurement. From the earlier example once again, let'south say your current rate is ¢ 11.85 per kWh.

4.6 kWh x ¢ eleven.85 = 54.51 cents

This is how much information technology costs to run your AC organization for an hour.

Cost To Run Air-conditioning All Dark- Let's say that the summertime day turned into a hot night and opening your window to let the cakewalk in won't cut it. Practice you lot want to know how much it costs to run your ac unit all night? If your HVAC unit runs for 8 hours in total, these are the costs:

54.51 cents x 8 hours = $iv.36

Cost To Run Air conditioning All Twenty-four hour period – What about if you keep your cardinal air running for the whole day – 24 hours per day in total?

54.51 cents ten 24 hours = $13.08 – The toll to run the HVAC system all 24-hour interval.

The to a higher place numbers confirm that air conditioners are not a cheap matter. The U.S. Energy Information Administration (EIA) 's estimate is that heating and cooling account for nigh 12% of U.Southward. home utility costs. These costs may be higher if your home HVAC unit of measurement is old (over five years), less efficient (not an Energy STAR rated model), or if you are paying a higher charge per unit per kilowatt of electricity.

FAQs

Below are answers to some of the questions y'all might take most your air conditioner toll:

How much does your utility bill become up with an air conditioner?

EIA estimates that primal air conditioning cost accounts for nearly 12% of U.South. home utility costs. The final number, however, will depend on unlike factors, including the efficiency of your unit, your thermostat settings, the outside temperature, and your electricity costs per kilowatt hour.

How much does AC cost per hr?

To summate how much electricity does a AC use per hour, you lot commencement demand to convert the tonnage of your unit into amperes, based on the below guide:

ii-Ton Air Conditioner – 15 amps
3-Ton Air Conditioner – eighteen amps
4-Ton Air Conditioner – 21 amps

Then, multiply the amps by the voltage of your outlet (220V is the standard) to go the wattage of your unit (W used per hour). Finally, multiply the number by your current electricity charge per unit to find your hourly HVAC cost to run. Y'all can use the free toll of running air conditioner reckoner resources online if you would like or follow our comprehensive guide to determine the price to run.
