Knowing the wattage of your AC unit allows you to find out the cost to run it. Air conditioner capacity is often described in British thermal units instead of amperage or wattage. To determine the cost to run a 5,000-Btu air conditioner, however, you'll have to know the amperage rating. In turn, you can convert that number to wattage. Once you know the wattage, you can find out the cost to run the air conditioner for an hour, a day, a week, a month or a year. Locate the amperage of your 5,000-Btu air conditioner. There will generally be a tag on the bottom or inside the filter panel with the specifications that you need. Most 5,000-Btu air conditioning units are rated at around 5 amperes. Calculate the wattage from the amperes. For example, multiply the 5-amp figure by how many volts there are at the outlet. In most cases this will be 110. Therefore, 5 x 110 = 550 watts. This figure will allow you to calculate your kilowatt-hours. Find out what you are paying for each kilowatt-hour from your local electric company.

The national average is approximately 12 cents. Determine how much the air conditioner would cost to run over a 24-hour period. Use the basic formula of watts x hours of use ÷ 1,000 x cost per kilowatt-hour = cost of operation. (Dividing by 1,000 changes watt-hours to kilowatt-hours.) For example, in this case the mathematical formula looks like this: 550 x 24 ÷ 1,000 x $0.12. The cost to run a 5-amp, 5,000-Btu air conditioner over a 24-hour period is about $1.60. Divide the cost per day by how many hours in a day to get an hourly cost amount. For example, $1.60 divided by 24. The answer shows that it will cost 6 cents to run every hour. Multiply the per day cost, $1.60, by seven days to get a weekly cost. In this instance it will cost $11.20 per week to run continuously. Multiply the weekly amount by how many weeks in a month (4) to get a monthly cost. In this case, the cost per month will be approximately $45. A yearly cost can be determined by multiplying the cost per week, $11.20, by how many weeks in a year, 52.

The total approximate yearly amount to run a 5,000-Btu air conditioner continuously will be about $585.

Window Air Conditioner Install Prices Window air conditioners aren’t the most efficient way to cool an entire home, but if you’re looking to provide heat relief to one or two rooms, this type of unit is very effective (which is why it is also known as a room air conditioner). This buying guide explains the major window air conditioner options as well as how much the units cost to purchase and install.

Window Air Conditioner Considerations The efficiency of air conditioners is described by their Energy Efficiency Rating, or EER. Ranging from a federal minimum of 8 to as high as 11.5, the EER is the ratio of a unit’s cooling capacity (in British thermal units per hour [Btu/h]) to its power input (in watts). Choose an air conditioner with an EER of 10 or greater to achieve energy savings. To provide adequate cooling and maximum efficiency, an air conditioner must be sized appropriately. To determine the correct air conditioner size you must look at two numbers: the output of the AC unit (in Btu/h) and the size of the room. As a general rule of thumb, an air conditioner requires 20 Btu for each square foot it is to cool. So, for example, a 200 square foot room would need an AC unit with an output of at least 4,000 Btu/h. Window Air Conditioner Installation Although installing window air conditioner units is a straightforward do-it-yourself task, if you’re physically unable to do it, or just would prefer not to, then a professional can do it for you.

There are steps you can take, however, to improve the efficiency of the air conditioner and/or make it a permanent installation, and for this, a professional is recommended. Replacing the air conditioner skirts with Plexiglas or Lexan will allow a much better air seal around the air conditioner, helping to ensure the efficiency of the unit as well as providing a view through the sides of the unit. Making an air conditioning unit permanent is the same as the modified temporary setup described above with the exception that it additionally requires the use of window silicone to permanently seal the unit from air flow. But keep in mind that this type of installation is meant for milder climates, not cold regions, as the AC unit itself is not insulating. Window Air Conditioner Average Costs The actual cost to purchase and install a window air conditioner depends on the size and type of the unit, the local economy, the presence of any installation complications, and other factors.
