Are air conditioners better than fans?


Fact Box

  • American electrical engineer Schuyler Wheeler invented the electric fan in 1886. 
  • The “Father of Air Conditioning,” Willis Carrier, designed “the first modern air-conditioning system” in 1902 after inspiration struck while waiting on a train platform where he realized he could “dry air by passing it through water to create fog.” 
  • The US Department of Energy reports that “three-quarters of all homes in the United States have air conditioners…at an annual cost of about $29 billion to homeowners.”
  • advises that maintaining indoor temperatures of 78 degrees and higher during the warm summer months is the most energy-saving.

Although air conditioning is considered one of America’s great luxuries, the cost of cooling our homes with an A/C unit is quickly depleting our finite natural resources. While fans also use electricity, they do not require nearly as much as A/C units, which means that they are vastly superior for anyone concerned with their carbon footprint

Aside from their energy efficiency, fans are also very cost-effective. Electric bills are typically much higher in the summer due to increased A/C usage. And with local power companies dependent on ever-rising natural gas prices, many people are planning ahead with more cost-saving alternatives to cooling their homes with A/Cs during heat waves.

Also, since A/C units utilize a refrigerant cooling system, they produce harmful emissions akin to the direct pollution of overly using cars for transportation. Fans are much friendlier to the environment. 

Fans are pretty much maintenance-free--except for occasionally keeping the blades clean--while air conditioning units require a lot of upkeep, such as changing coolant and filters and hiring specialized repair people when units break down, which can also be expensive and time-consuming. 

Air conditioning can also lead to poor health outcomes through dehydration and encouraging poor home air quality. This can affect the skin barrier and even dry out sinuses to the point of increased nosebleeds in certain people. And adding more dry air to the home can be uncomfortable and unnecessary for those already living in arid regions. 

Overall, fans are better for the environment, household budgeting, and, ultimately, our health.

Choosing between air conditioning units and fans is easier than most people think. That's because A/C doesn't only provide superior cooling, but it also delivers more advantages than its alternative. 

In some scenarios, A/C is the only ideal choice. For example, the CDC doesn't recommend using electric fans when the temperature is above 95 degrees Fahrenheit. Fans increase hot air circulation, which results in sweat evaporation and increases the risk of dehydration, electrolyte imbalance, and other heat-related illnesses. 

Fans are also ineffective in humid spaces. And because they can't lower overall humidity, individuals sweat more slowly and feel hotter. 

On the other hand, air conditioners can double as dehumidifiers. Their 'dry mode' provides many benefits, like protecting the overall property from excessive moisture. 

Air conditioning is also beneficial while cooling large areas. Its ability to regulate temperatures helps ensure the comfort of everyone sharing a space. A/C units even assist offices in complying with safety regulations that mandate certain temperatures. 

And on the topic of health and safety, many A/C systems include built-in air filtration. In addition to ensuring cleaner air, air filters reduce allergies, dust, and other particles. This, in turn, leads to better sleep and may even increase life expectancy.  

Most people avoid investing in air conditioners because they fear hefty bills. However, there are ways to minimize the energy these units use. For example, selecting high-efficiency air conditioners can reduce energy consumption by up to 50%. Therefore, energy efficiency shouldn't be a reason to rule out getting an A/C. 

Investing in an air conditioner is far superior to bearing with the heat or having to be stationed in front of a fan to find relief.
