We’ll discuss the many factors that affect cost below, but know that high cooling capacity and high energy efficiency are two of the biggest ones.
What Factors Affect The Price Of a Window Air Conditioner?
When trying to get to the bottom of “how much is a window air conditioner?” there are a number of variables to consider.
Among these are:
- Ability to Cool
- Energy Conservation
The size of the area that must be cooled by the window air conditioner is one of the primary factors in determining the cost of the unit.
Of course, the greater the cooling capacity of a window air conditioner, the more electricity it will consume and the higher the price it will be.
A window air conditioner’s BTU rating is a good indicator of how well it cools a room. This is the standard measurement for determining a device’s cooling efficiency.
The BTU rating indicates the size of the room that can be cooled by the air conditioner.
Here are some common BTUs for window air conditioners:
- 5,500 British Thermal Units (or 150 square feet)
- 8, 000 BTU (or 350 square feet)
- 800 square feet or 9,000 BTU
- 1,050 square inches, or 10,000 BTUs, of heating power.
- A unit of heat output equal to 12,000 BTU (or 550 square feet)
- 730 square feet or 14,000 BTUs.
The price of a 14,000 BTU window air conditioner will naturally be higher than that of a 5,000 BTU unit.
Having the appropriate sized window air conditioner is crucial for effective cooling.
An improperly sized window air conditioner runs the risk of either failing to adequately cool the space or causing excessive energy use and a corresponding spike in your monthly electricity costs.
Similar principles apply to through-the-wall air conditioners, which are installed into a wall rather than a window and look and function similarly to window air conditioners.
A through-the-wall air conditioner is an option if you want to keep your window unobstructed. Review our top picks for through-the-wall air conditioners to help you make a decision.
When figuring out the answer to the question “How much does a window air conditioner cost?,” energy efficiency is another factor to think about.
A more expensive air conditioner is not necessarily a more efficient one. In fact, the Energy Efficiency Ratio (EER) or Combined Energy Efficiency Ratio (CEER) is the most reliable indicator of how well a window air conditioner controls energy usage.
Both the Energy Efficiency Ratio (EER) and the newer, more stringent, Cooling Efficiency Ratio (CEER) were implemented by the Department of Energy in 2014. Both of these figures, for instance 10.8, 11.1, and 12.2, are displayed on the Energy Guide label alongside the air conditioner.
Keep in mind that a higher EER or CEER number indicates a more energy-efficient air conditioner, but it also indicates that the unit will cost more to operate.
Higher purchase prices on energy-saving appliances are inevitable.
It’s true that not all air conditioners for windows are created equal. While some are built with only the most essential features, others boast more sophisticated technology like Wi-Fi, programmable thermostats, and adjustable airflow.
More features mean a higher price tag for a window air conditioner.
The cost of a window air conditioner also depends on the brand.
Like any other product on the market, the price of a window air conditioner will depend in part on the company’s reputation.
Choose a well-known brand or one that has a sizable market share if you’re in the market for a window air conditioner.
This increases the likelihood that you’ll get a top-notch product and helpful assistance in the event of a malfunction.
How Much is a Window Air Conditioner in Total?
As you saw, the price of a window air conditioner can range from $138 to $500, depending on the model you select and other factors like its cooling capacity, energy efficiency, and features.
The average person can expect to pay as little as $0.52 per day to run a window air conditioner.
What this means is that the total amount you spend on a window air conditioner is totally up to you and the amount of time you plan to spend using it.
Most people benefit from having their air conditioner on for eight hours a day. However, more or less usage may be preferable.
The question of how much it costs to run a window air conditioner is more difficult to answer, of course, because there is no single, all-encompassing figure.
However, we do hope that the data presented here has helped you estimate the total monthly and hourly costs associated with operating a window AC unit.
Running Cost Of Windows AC Unit
You can figure out how much power your window air conditioner uses by calculating:
- What determines how many amps an air conditioner uses is not just its size, but also its Seasonal Energy Efficiency Ratio (SEER). The current consumption of a two-ton air conditioner with a SEER rating of 16 is about 15 amps.
- Air conditioners for windows typically have a 240-volt power cord and a wattage requirement. Once you multiply the amps by the wattage, you get 4,320 watts.
- KWh: The kilowatt-hour can be calculated as follows: (Amps x Watts)/(1000). This is the standard unit of electricity consumption in the United States. Inputting the aforementioned data into the formula (4,320/100), we get a result of 4.32 kWh.
Per Hour Running Cost Of Windows AC Unit
When you know how much electricity the air conditioner uses in a given hour (4.32 kWh), you can divide that number by the price per kilowatt-hour in your area to get the cost of running the unit for one hour. If you live in Ohio (where the cost per kWh is $12.55), for instance. After multiplying the price (12.55) by the amount of energy used (4.32), we get a total of 54.216.
That equates to $0.54216 in energy costs per hour for your AC unit.
Per Day Running Cost Of Windows AC Unit
In order to calculate the daily cost of operating your air conditioner, multiply the cost per hour by the number of hours it is used. So, if you use your AC for 8 hours a day, you would multiply that by the cost per hour ($0.54216).
Your daily operating cost for the air conditioner is thus ($4.33).
Great! What I mean is, “how much does it cost to run a window air conditioner?” Electricity rates can have a significant impact on how much your air conditioner ends up costing you. Depending on their British Thermal Unit (BTU) and wattage, window air conditioners can have hourly electricity costs anywhere from $0.065 to $0.195.
