How Much Power Does An Air Conditioner Use?

An air conditioning unit is an indispensable appliance in homes within the Phoenix area. AC units help cool the rooms to enhance your comfort. So how much electricity does your AC use? The amount of energy consumed by your AC depends on several factors. Your installation technician can help you reduce your air conditioner’s energy consumption. Read on to learn more.

How Much Electricity Does an Air Conditioner Use?

Several factors impact the amount of power your air conditioner consumes. Understanding these factors makes it easier for anyone who wishes to estimate the power consumption of their AC. The primary determinant of the amount of power consumed is the type of air conditioner you have installed in your home. 

How Much Power Does a Central Air Conditioner Use?

Most central air conditioners use between 3000 and 3500 watts per hour during a warm month. Since Phoenix is a warm area, you can expect your power consumption to be within that range. However, if your ac runs on fan mode, the power consumption can be as low as 750 watts per hour.

How Much Electricity Does a Portable Air Conditioner Use?

The size of your portable air conditioner matters a lot when it comes to power consumption. A medium-sized portable ac consumes about 2900 watts per hour, while a fairly larger one can consume up to 4100 watts per hour.

Window Air Conditioner Energy Usage

Like portable air conditioners, energy consumption in a window ac unit depends on its size. Larger window air conditioners use about 1440 watts per hour, while medium-sized ones use about 900 watts per hour. However, if you have a smaller one, your energy consumption drops to about 500 watts per hour.  

Understanding Air Conditioner Power Consumption

The energy usage provided in the previous sections gives you an estimate of what most air conditioners use. So does ac use a lot of electricity? To get the actual energy consumption for your AC, you need to compute it. Calculating energy consumption should not be complicated; just check the power rating on your AC. This information is provided in watts, but your electricity tariffs are in kilowatts.

You will need to convert the watts to kilowatts by dividing the hourly consumption rate by 1000. If the power rating of your AC is 100 watts per hour and it runs for 60 hours, your energy consumption is 6000 watts, which is equivalent to (6000 ÷ 1000) kilowatt-hours or 6 kWh. From this, you can get your energy consumption in dollars by multiplying the value by the cost of electricity in your area. In the state of Arizona, the cost of electricity averages 12.8 cents per kilowatt-hour.

However, your AC does not run continuously but in two cycles of 15 minutes each per hour. That means your electricity consumption is about half what you calculated using the energy rating. Most homeowners spend about $400 annually on air conditioning. However, this figure may change depending on several factors.

Factors That Affect Air Conditioner Electricity Usage

Now that you know how much electricity your air conditioner uses, the next step is to learn why your AC consumes more energy than others. While the type and size of your ac may determine your power usage, other factors may make you pay more. Here are some of those factors:

Your Air Conditioner’s Capacity

The air conditioner’s capacity measures the ability of the AC to cool your entire home. Your air conditioner’s capacity is measured in British thermal units (BTUs). You need 20 BTUs to cool an area of one square foot. The larger your home, the more BTUs are required to cool every room. Homeowners with large homes spend more than those living in smaller ones.

Your Air Conditioner’s Efficiency Rating

How much electricity an air conditioner uses is based on the efficiency rating of the AC. Each ac unit has a Seasonal Energy Efficiency Ratio (SEER) rating. The SEER rating gives you the maximum efficiency of the ac unit per season of cooling. A higher SEER rating means the ac is more efficient. Federal regulations set the minimum SEER rating at 13 or 14, depending on where you live. However, you can still get an ac with a SEER rating of 25.

Climate

Why does ac use a lot of electricity? This question is common in areas that have a warm climate. Since the primary role of the AC is to cool your home, you would expect it to use more electricity in warmer areas like Phoenix than in cooler regions.  

Your Maintenance Routine

Poorly maintained air conditioners consume more energy. Regular maintenance can help reduce the energy consumption of the ac unit. To keep the air conditioner at its optimal efficiency, you should schedule professional maintenance twice a year. In-between the professional maintenance schedules, you can change or clean the filters on your own. If you are among those who wonder whether an AC uses a lot of electricity, you will be surprised to learn the amount of energy you can save through regular maintenance.

Temperature Settings

The temperature settings on your ac also impact your energy consumption. Most ac manufacturers recommend setting the temperature to 75 degrees. If you keep changing the temperature settings, your energy consumption goes high.

Air Flow

It’s important to consider all components of the air conditioning system to help distribute the air it’s blowing. Have your registers been cleaned and sealed? Is your ductwork clear and free of particulates? Is your system’s blower motor operating at maximum performance? Has your coil been cleaned in the last year? If you don’t know or have answered “no” to any of these, it’s time for a professional duct cleaning. This will not only promote proper airflow in the home but help keep it free and clear of contaminants.

Insulation

Insulation helps retain the cooled air in the room or prevent hot air from getting in. A well-insulated room reduces the workload of the ac to save energy. We recommend a minimum of 3 to 4 inches of insulation with an R-value of at least R-30 for maximum energy efficiency.
