Air conditioners are a necessary piece of equipment in most households. In the summer, they circulate cold air around the house to maintain a comfortable temperature. It’s critical to know how much electricity air conditioners consume in order to determine how much money you can set aside for your energy plan.
Some houses just have one air conditioner, but many two-story houses have two air conditioners, which can significantly increase electricity use. Electricity consumption varies depending on a variety of circumstances. A residential air conditioner uses roughly 3,000 watts of electricity per hour on average. That’s 72,000 watts of electricity per day if you leave it on all day! Running it in ‘fan-only’ mode, on the other hand, will only use roughly 750 watts per hour.
Window air conditioners can use up to 1,440 watts for large models, 900 watts for medium models, and 500 watts for smaller versions, while portable air conditioners can use up to 4,100 watts. Manufacturers of air conditioners publish information on the label to help you figure out how much electricity you’ll need. Most air conditioners run for an average of 1,600 hours per year, or 132 hours per month (depending on season and location).
What is the Expense of Using Air Conditioning?
On average, an air conditioner costs $0.06 to $0.88 per hour to run. Consider the cost of air conditioning on a monthly basis (assuming it runs for 8 hours per day). The lowest affordable option costs $14.40 per month, while the most expensive option costs $211.20 per month. Based on these figures, the annual cost would be between $172.80 and $2534.40.
Multiply the wattage by the number of hours of energy consumption to get an estimate of your daily energy costs. For example, if the air conditioner uses between 3,000 and 5,000 watts and runs for nine hours each day at $0.10 per kilowatt, the daily cost is between $2.70 and $4.50.
What Factors Influence Air Conditioning Costs and Energy Consumption?
The cost of air conditioners and the amount of electricity consumed can both rise as a result of several variables. The size of the unit and the quantity of space it must cool will have a considerable impact on the figures. A single-unit 1,600-square-foot home uses far less energy than a 3,000-square-foot residence.
Another thing to think about is the unit’s energy efficiency. The EER (energy efficiency ratio) and SEER (seasonal energy efficiency ratio) might affect the amount of energy used to operate the equipment. Units with higher EER and SEER consume significantly less energy than those with lower ratings.
People who utilize fans in conjunction with air conditioners can reduce their electricity use. Maintaining the units, as well as changing the AC filters and outdoor coils on a regular basis, can help reduce energy use. Additionally, lowering the amount of outside air that enters the house and increasing fan usage will lower costs. Other approaches, such as maintaining a constant airflow rate, decreasing airflow path blockages, and removing heat-producing objects, can also help.
Is Running a Window Air Conditioner or Central Air Cheaper?
The average cost of installing a central air conditioner is $5,700. It might cost anywhere from $1,700 to $10,900, depending on the size of your home or structure. On average, a window air conditioner costs $295, but keep in mind that these devices can only cool a limited area. The unit might cost anywhere from $75 to $1,000 depending on the size and brand. In comparison, the larger the home, the more cost-effective a central air conditioner is.
If you wish to cool the entire house, multiple window air conditioners will use more energy than a single properly sized central air conditioner. If you only need to cool a single room, though, a window air conditioner will be the most efficient option.
Are Air Conditioners More Energy Efficient Than Fans?
A fan consumes 5 to 9 times less energy than an air conditioner. While the actual number varies by size and model, practically all of them fall under this category. An air conditioner uses a lot of electricity even on the lowest setting to cool air, yet a fan saves a lot of money by just rotating a blade. If you want to know how much money you’ll save in your own house, an energy meter can help you figure it out.
Running window units costs one-third less than running a 2.5-ton central air conditioning system for the same length of cooling time. On the other hand, the size of your home will determine which cooling system is best for you and your family. Even if it is an energy star product, standard desktop or standing fans are always less expensive to run than air conditioning equipment because fans require significantly less energy to work effectively.
When is the Most Cost-effective Tme to Run Air Conditioning?
Customers are charged more for electricity used during “peak” afternoon hours, when demand is highest. When demand is reduced, electricity is most economical during “off-peak” hours. Overall, the cheapest seasons are fall and spring since energy demand is lower because heaters and air conditioners are utilized less during these months.
Many people use heaters in the winter, which raises costs, and many rely on air conditioners in the summer to keep cool. Summer, on the other hand, is often a time of higher demand than winter, therefore summer electricity rates will be higher. The timing of peak and off-peak electricity use is, however, largely dependent on where you live and the weather conditions.
What are the Advantages and Disadvantages of Air Conditioning?
There are various advantages to having an air conditioner. Air conditioners are especially good at cooling large rooms and keeping the house cool for long periods of time. Dehydration is also reduced in air-conditioned environments. Air conditioning benefits patients with respiratory disorders like asthma because it improves the air quality of the environment by eliminating allergens.
The production of energy alone for air conditioners emits around 117 million metric tons of carbon dioxide each year, harming the environment and contributing to climate change, but for most people, the cost of using air conditioners is the primary disadvantage. The costs of installation and maintenance, especially for central air conditioning systems, can be significant.
Furthermore, while air conditioners benefit some people, they can cause skin dryness in others. The same is true for respiratory disorders; while it may benefit some, it can also harm others, resulting in respiratory infections and allergies, especially in older machines. Furthermore, air conditioners can be quite noisy. Finally, too much time spent in air-conditioned environments might lead to heat sensitivity.
How Can I Save Money on My Air Conditioning Bill?
The most important thing you can do to save energy while cooling your home is to make sure you’re not cooling the outside. If your home isn’t brand new, the cold air inside is most likely leaking out through broken door and window seals, a poorly insulated attic, and other small gaps.
Close the blinds to decrease the sun’s potential to influence the temperature of your home. Instead of expecting your air conditioner to cool your house to 68 degrees, adjust the thermostat to 72 degrees, which will consume less electricity. You can save money as well, up to 10% every year or more. Finally, you are not required to use the same setting throughout the day. Change the parameters according to the time of day.
Finally, you may shade your property by planting trees around it. A smart thermostat makes temperature control more easier and can save you up to ten percent on your energy cost. Consider getting ceiling fans if you don’t already have them to assist circulate the air. Heat rises, therefore if you don’t want to use air conditioning, spend more time on the lower floors of your home if you have one.
