This calculator uses the average watt rating (100 Watts) for a Air Conditioner. You can input your Air Conditioner’s details to calculate the exact usage and cost of your device.
Enter how many hours per day you estimate you run your Air Conditioner. If it is less than one hour use a decimal. For example, 30 minutes would be .5 and 15 minutes would be .25.
Input the wattage of your Air Conditioner. If you are unsure enter the average wattage for a Air Conditioner: 3,500.
Enter the price per kilowatt-hour (kWh) you pay for electricity. If you are unsure you can use the average rate per kWh in the US (10 cents) or find the kWh rate in your area here.
Air conditioners are some of the essential appliances in most households. It maintains a comfortable temperature during the hot summer by circulating cool air around the house. However, the unit's energy consumption is a concern many people have when they consider installing an air conditioner.
Scheming your budget will be easier if you understand how much electricity an AC uses. Here are some tips and information you need to help you along.
For various living environments, different models of air conditioners are more appropriate.
For instance, a split or packaged air conditioner is what you need if you live in an area where most of the year is spent in intense heat.
However, you might have to consider a window unit or a portable air conditioner if you can't install central air in your house for whatever reason.
Before choosing a unit, you should also consider the air conditioner's size.
Here are some of your choices to assist you in reaching a more strategic decision:
Typically, split air conditioners consist of two components: an external compressor and an internal fan system. The louder component exits the building, where the noise and heat will be less disruptive, and ducts are used to circulate the cool air throughout the house's interior.
Central air conditioning is provided through packaged systems that are built in conjunction with a dual heating and cooling system (HVAC).
It is considered the most effective and (roughly) least expensive alternative air conditioning if your home already has forced air heating (and consequently ducting).
Contrary to conventional air conditioners, which use compressors that alternate between on and off to change temperature, inverter air conditioners operate at variable speeds and consume only the energy required to maintain the desired temperature.
Since they chill more effectively and consume less energy than conventional air conditioners, they are more expensive initially due to the relatively new nature of the technology.
Window units are independent air conditioners that are available in a variety of sizes. They can be installed simply for the months required or occasionally installed permanently by being implanted through the house's wall.

Dehumidifiers and portable air conditioners have a similar appearance. They are wheeled cabinets with all the necessary cooling system parts, just like window units. They must be vented to the outside; a kit is typically provided for this. While some portable appliances evaporate independently, many require you to empty a water tank regularly.
The amount of power used changes depending on several variables. A central air conditioner typically consumes 3,000 watts per hour during hotter days.
Your air conditioner uses about 750 watts per hour while operating in fan-only mode. Mid-sized air conditioners require roughly 2,900 watts per hour, whereas large, portable AC units can use up to 4,100 watts per hour. A large window air conditioner can take up to 1,440 watts, a medium one 900, and a tiny one 500.
You can reduce your air conditioner's wattage in several ways. First, replace an older unit with a highly efficient model. Close your windows and doors to prevent your home from being excessively hot during the summer.
For your AC to provide appropriate cooling, it must work harder, which uses a lot of energy. Your appliance's temperature settings and operating time will also impact energy usage. Most homeowners keep their homes more excellent than what is deemed necessary.
To prevent overcooling, keep the temperature in your rooms between 72 and 75 degrees. Ensure the unit's temperature setting is no lower than 8 degrees from the outside temperature.
You should also turn off heat-dissipating devices while not in use. Additionally, ensure your home is appropriately insulated to prevent conditioned air from leaking out of crevices.
If your home has cabinets, keep them closed at all times. They increase the air your air conditioner should chill when opened, using more energy than necessary. Change or clean your AC filters frequently. A clogged filter reduces airflow, which puts pressure on the appliance and increases energy use.
Have a professional check for refrigerant leaks, blocked coils, and a broken compressor, which can reduce the effectiveness of your unit. Be sure to get an air conditioner that is appropriate for the size of your home.
If you get a system that is too small for your needs, it will work very hard to cool your home. An oversized unit will cool your house more quickly, but a larger capacity uses more energy.
