To get a general idea of your daily energy costs, multiply the wattage by the number of hours of energy consumption. For example, if the air conditioner consumes between 3,000 and 5,000 watts and runs for nine hours each day at a cost per kilowatt of $0.10, the daily cost ranges from $2.70 to $4.502.
The average cost per kWh in the US is currently $0.11, according to the Energy Information Administration (EIA). This means an AC unit could cost you from $5.17 to $5.94 per day to run. Or about $155-$178 per month you're running it.
Leave Your Air Conditioner On
You might think you're saving money by turning your AC off when you step out of the house. However, a wave of heat and humidity can sneak into your home in the interim. Therefore, leaving your air conditioner on all day in hot temperatures is more energy efficient.
Electricity usage can vary depending on different factors. On average, a home air conditioner can use about 3,000 watts of electricity an hour. If you have it on all day, that's 72,000 watts of electricity a day! However, running it on the 'fan-only' mode will only consume about 750 watts an hour.
"But the average monthly cost for most people is anywhere from $70 to $144 a month in the summer." The type of cooling system in your home can also affect energy use, but not as much as you might think.
How Much Electricity Does a Ceiling Fan Use? Ceiling fans come in a variety of wattages, but a standard 48-inch model uses about 75 watts per hour on average. This would cost you about $0.01 per hour, or $6 per month if you leave your ceiling fan on 24/7 all month.
Heating and cooling: 45-50%
The largest electricity consumer in the average household is your heating and cooling appliance. By a long shot. Central air conditioners and heaters use tons of energy in order to keep your home set to the right temperature.
Best AC Temperature Settings While You Are Home
As you consider the most comfortable room temperature for your lifestyle and family, keep in mind that for each degree that you set your thermostat above 72 degrees, you can save up to 3% on your energy bill.
The constant running of your AC unit will reduce pressure in the evaporator, or cooling coil until it freezes over, according to Cool Today. This is why in some cases, this constant running can be dangerous.
Although many people believe that it is more costly to turn your AC on and off vs. leaving it on, this is entirely false. People often base this belief on the idea that powering on your system requires a burst of energy, so leaving it running would minimize energy usage by reducing these bursts.
There are a few reasons you don't want to run your AC system all the time: System stress: Your air conditioner unit needs time to take a break. If it's running all the time, it can be damaging to the system and lead to the need for a costly replacement. Energy bills: The cost to run your AC 24/7 can be high.
Let us now calculate the AC power consumption using an example. For example, there is a branded 1.5 kW AC that runs 8 hours per day. As a result, the total power consumption of that air conditioner will be 1.5 * 8 * 30 =360 units per month.
While running your air conditioner will cool your home, it consumes a lot of energy, leading to higher electricity bills. Yet not using the air conditioner isn't practical.
Cons to Keeping Fan Continuously Running:
It could cost you hundreds of dollars a year. The average unit has a 500 watt fan, which uses almost as much energy over the course of the year as a refrigerator, resulting in a $50/month bill.
A ceiling fan is made up of different parts and pieces, and they will wear out over time. Sure, your ceiling fan can run throughout the day and night without issue, but running it for several days or months on end may not be the smartest choice and will reduce the overall lifetime of your fan.
To find how much electricity your TV uses, multiply yearly electricity use by average electricity rate in your area. Using a TV 21 hours a week will use about 54.75 kilowatt-hours of electricity per year. It costs an average of $1.30 to run a TV for a month and $15.54 to run for a year.
On average, a central air conditioner uses around 3,000 to 5,000 watts of electricity per hour. With the average U.S. residential electricity rate at around $0.13 per kilowatt-hour (kWh), the daily cost of running your central air conditioner for 8 hours would be approximately $3.12 to $5.20.
Studies have shown that, on average, shutting off your air conditioner at night will reduce your total cooling costs by somewhere around 30% compared to leaving it turned on 24 hours a day. However, this depends in large part on how warm it is at night as well as the humidity level.
While aircon can be expensive to run, your overall monthly cost can be reduced with the right model and wattage. Not only should you consider the space you want to cool and heat, but what your energy budget is.
Sixteen percent of the rate increases in California have come from the state's efforts to protect the grid against wildfires. Colorado, Texas, Hawaii, and Oregon have also seen significant wildfires in recent years that will likely push future bills higher.
