Being stuck in a hot, sticky home or office is not fun for anyone.
While air conditioning was once considered a luxury item, it has now become a staple in almost every home in the United States, and with many other countries quickly catching up with this metric.
To help shine some light how air conditioner use has changed over the decades, the amount of energy it consumes, and how much it costs to cool down our homes, we’ve put together this comprehensive list of air conditioning facts and statistics.
How do we know this? Because we scoured the Internet to find all of the air conditioning statistics available in order to bring them to you here.
Sharing is Caring
Feel free to share these facts on your own website, through social media, in presentations, etc. We only ask that you kindly place a reference link back to this web page so that others can make use of these statistics too.
Also, if you’re interested we have two detailed guides on how to the best low-cost air conditioner for your home. Check them out here:
AC Facts and Statistics
- A 2009 survey showed that 87% of U.S. homes have some form of air conditioning. In 1993, only 68% of all occupied housing units had AC.1
- In the U.S., it’s more common to have an air conditioning unit that a garage, dishwasher or even dining room.9
- 18% of households below the poverty line do not have any air conditioning equipment at all.1
- About a third of households below the poverty line use room air conditioning compared to 15% of households with an income above $100,000.1
- Only 42% of homeowners call a professional to perform routine maintenance on their air conditioning system. Of those who do, 40% of those air conditioners have a longer lifespan.1
- Air conditioners emit 117 million metric tons of carbon dioxide each year. This averages out to be about 2 tons per home.2
- Up until the last part of the 20th century, air conditioning systems used chlorofluorocarbons (CFCs) as their refrigerant. In 1995, CFC production was stopped because it destroyed the Earth’s ozone. In the 1980s, halogenated CFCs (HCFCs) were developed as a replacement, but these are also causing damage to the ozone. An eco-friendly replacement for HCFCs is expected by 2030.2
- In the U.S., households in the South, Midwest and West are most likely to use a central air conditioning system, while those in the Northeast use a room air conditioner.1 (Examples include a window air conditioner and ventless portable air conditioner units.)
- In the Southern states, 67% of central air conditioning is used all summer long.1
- Turning on the air conditioner in a hybrid gas-electric vehicle results is a greater loss of gas mileage and vehicle range. Depending on air conditioner load, MPG can drop between 6-40% and vehicle range is reduced between 9-38%.5
- 6% of all electricity produced in the United States is from residential air conditioning.2
- Homeowners in the U.S. spend an estimated $29 billion dollars on air conditioning costs.2
- A programmable thermostat can save up to $180 in air conditioning costs each year.6
- Due to higher temperatures in the summer, electricity demand is 10-22% higher than in the winter.7
- In the U.S., 5.5% of passenger vehicle fuel is used for running an air conditioner.8
- The average household spends about $300 each year on air conditioning and refrigeration.
- In 1990, 1% of Chinese households had an air conditioner compared to 62% in 2003.3
- In 2010 alone, 50 million air conditioning units were sold in China.3
- In 2007, only 2% of India households had an air conditioner, but sales are estimated to grow by 20% each year.3
- In households with central air conditioning, CO2 emissions can be reduced by adjusting the thermostat. For each degree it’s set above 72 F, 120 pounds of CO2 emissions can be eliminated.4
