Running the Fan on Your Air Conditioner Continuously: The Pros & Cons
If you're trying to stay comfortable in the summer heat, you might feel tempted to constantly run your air conditioner's fan. But is running the fan on your air conditioner continuously really as advantageous as it seems? Bates Air & Heat LLC, the top-rated heating and air conditioning services in Vero Beach and the surrounding area, breaks down the pros and cons.
The Benefits of Continuously Running Your Air Conditioner's Fan
With more frequent days of excessive summer heat, air conditioning is now more than a luxury; it's essential for your family's safety. With your health in mind, there are several benefits to running your air conditioner fan constantly.
Reduced Dust
When you constantly run your fan, the dust has less chance to settle on your furniture and other surfaces throughout your home. While you'll never rid your home of dust completely, using your fan directs more of it to your filter than the living spaces of your home. This means your family will likely experience fewer respiratory issues.
Reduced Allergens
Dust isn't the only thing that can aggravate your allergies. When you run your fan, you're preventing particulates like pet dander and pollen from settling in one place and causing problems. The more these substances circulate, the more chance your air filter has of catching them.
Fewer Harmful Organisms
Organisms like bacteria and viruses can become airborne, eventually settling on your surfaces or entering your respiratory system. According to the American Lung Association, circulating your air more frequently directly reduces the level of viruses and bacteria in the air and their likelihood of spreading.
Consistent Humidity Levels
Did you know that lower humidity levels can cause problems that are just as severe as high humidity? Whereas high humidity can damage your property and even cause heat exhaustion, humidity that's too low increases your risk of catching the flu and other viruses.
Running the fan constantly stabilizes the moisture levels within your home. More humid rooms, such as the bathroom or kitchen, will stay dryer when you constantly run your fan.
Fewer Abnormal Temperatures
If you notice some rooms in your house are colder or warmer than others, running your fan can distribute the conditioned air more consistently throughout your house. Some rooms are more susceptible to these variations, such as areas above your garage or converted attic spaces. If you have vulnerable living spaces that you use frequently, consider keeping your fan going while you're home.
Greater Air Conditioner Life Expectancy
One of the longest-lasting benefits of running the fan on your air conditioner continuously is that it can extend the life of your air conditioner. Because it prevents your device from starting and stopping as much, it reduces the stress on your air conditioner. When combined with regular maintenance, it can help your device last between 10 and 15 years.
The Problems of Running Your Device's Fan Continuously
If you're searching "keeping the fan running on my air conditioner," you should also be aware of the disadvantages of consistent fan use. While it's great for your health, it also presents a few challenges.
Higher Energy Bills
The biggest problem with running your fan consistently is that it increases your energy bills. Even though your air conditioner won't be actively cooling the air, powering the fan still consumes a significant amount of electricity. You'll pay more to run the fan on older air conditioner models when compared with newer ones. You'll likely have to carefully weigh the costs against the benefits to determine if it's truly worth it to keep your fan running constantly.
Reduced Life Expectancy of the Fan
While running the fan constantly can prolong the life of your air conditioner unit as a whole, it can actually reduce the life of your HVAC fan. Your fan requires a motor, which, just like any mechanical device, wears out faster the more you use it. That said, your HVAC technician can replace the fan motor for a more affordable price than a new air conditioner.
You can help prolong the life of your fan motor by regularly changing your air filter, which, under normal circumstances, requires attention every 30 days.
More Frequent Filter Changes
With more air circulating through your home, dust and debris will accumulate faster on your air filter. With your fan constantly running, you should check your air filter every two weeks. If you have more pollutants in your home than average — for example, if you smoke or have pets — consider checking your filter weekly to determine if it needs cleaning or replacing.
What happens if you let your air filter stay dirty? Not only will your energy bills skyrocket, it won't purify your air as well, and you risk severely damaging your device. If you're running your fan consistently for the health benefits, consider how much more you'll spend on air filters.
Less Control Over Temperature
While it seems counter-intuitive, running your fan actually decreases the control you have over your temperature. In the summer, it will blow more warm through your home, while in the winter, it circulates colder air. Without the proper thermostat setting, this means you'll run your air conditioner longer to stay comfortable.
