Should You Be a Fan of Running Your AC Fan 24/7?

Should You Be a Fan of Running Your AC Fan 24/7?

The air conditioner plays a vital role in our comfort this time of year. It ensures we have pleasant days and better sleep at night. However sometimes, that comfort can come with larger energy bills.

Efficiency keeps us cool and comfortably in our budget, too. So when we hear about a potential lifehack like keeping the heating and cooling system’s fan running all the time, we want to know the truth of the tip. Is it better to constantly keep your AC’s fan on? Read on to find out more!

Pros and Cons of Running the HVAC Fan 24/7

Some people might not realize that most systems offer you the ability to tell the fan to run all the time. We set our thermostats and let the system do the work of figuring out when they should run. Yet for many, this option gives them some appealing benefits:

  • Leaving the fan on eases the strain on the HVAC system. Constant motion means fewer stops and starts, which can extend the lifespan of your unit.
  • Constant fan use keeps the air in your home circulating through your air filters and UV sterilizers if you have them. People with allergies may appreciate the increased filtration of the air they breathe.
  • Increased airflow can reduce the number of hot and cold spots in the home, and provide a more consistent temperature. This distribution of heat and cooling can really help in homes with notorious hot spots.

Running the HVAC fan all the time does come with drawbacks, however. If these issues outweigh the benefits for you, leaving the fan on constantly may not be for you.

  • Continuous circulation means increased energy use. An HVAC fan uses power comparable to your home refrigerator. Leaving the fan on in your HVAC unit can cost hundreds of dollars per year.
  • You will need to clean your filter more frequently, as increased airflow through it means a faster buildup of pollutants.
  • During the summer months, constant HVAC fan use may blow more hot air into your home, causing your AC to run more often. The opposite is true in winter, forcing your heater to run more often. It may also bring more dirty air into your home.

What about the ever-popular “auto” setting? It, too, has points to ponder:

  • The “auto” setting is cost-effective, since it only works when it needs to. You will also have to change the filter less frequently, saving you money on spare filters.
  • The automatic setting works better for dehumidification. Since the fan stops turning, the system has the opportunity to drain moisture to the outdoors instead of blowing it back into your home.
  • Constant airflow does allow a more even distribution of heat and cooling. Letting the fan only work when needed allows more hot or cool spots in the home.
  • All the stops and starts can wear out the fan faster.

Customer Reviews

This was an exceptional experience! We woke up to our A/C on but not cooling (it was 6am and already 81 in the house). The person who set up our appointment was very nice, able to get us seen same-day, and let us know of some options to help save us money.

-Christy Cormier

The service from Sam and Chris was excellent! They were very knowledgeable and professional. They were able to answer all of my questions and completed all of my electrical issues. I will definitely use them again for future jobs. Thank you!

-Adrienne Beal

From the get go I could tell that the Snyder employees were truly professionals and didn’t push to make sales like other companies I’ve talked to my whole life. They took the time to explain so that I could make a decision. The installers and later the duct cleaners were very respectful during their work here. Thank you.

-Mike Daniels

Snyder Heating and AC is dependable, always on time and techs have always been courteous and knowledgeable. Emanuel was a great addition to the company. He was friendly and knew what he was doing. Thank you for great service.

-Linda Ackley

Snyder came in and did a total overhaul of our duct system. They had a great knowledge of what to do to make our home so comfortable! The technicians were all so professional and took great care of us! We’re so thankful for their expertise. Great and easy communication with the call center. We will definitely use them again!

-Crystal Hill

Snyder provided an amazing experience from start to finish. Most of us dread getting estimates with pressuring salespeople. Erik was a great guy, explained all my options and didn’t try to pressure me to act quickly! Justin followed up with my husband and I to offer further assistance in our decision. Again, no pressure, just helped with our follow up questions.

-Michele Bauer

Very prompt, professional, courteous, and cleaned up after repair. Had water line break in my front yard and no pressure. Very pleased and would highly recommend Snyder for all your plumbing, and AC needs. Thank you for making a rough morning get better with ease and professionalism.

-Chuck Jr.

Snyder was easy to get in contact with and had availability the next day. Clint came out and needed some parts so had to reschedule us for the next day for installation. He did a great job converting our old 3 knob shower to one. Looks great! Professional and courteous. 100% recommend this company, especially Clint.
