Should I Set My Thermostat Fan To On?

People can get confused about how to properly set their thermostat fan. Remember not to focus solely on the heating and air conditioning switches when adjusting the temperature on your thermostat. The fan switch shouldn’t also be neglected because it can highly affect the way that your HVAC comfort system works. The following guide gives you tips on how to properly set the fan on your thermostat.

Using the On Switch for Your Thermostat Fan

If you want to ensure that the air pushed into your home is clean, you must turn on the “on” setting of the thermostat fan switch on your thermostat. The air will then be pushed through the filtration system and cleaned before being sent into your home.

There are a couple of good reasons to set your thermostat to on, specifically in the summer. The first is that you get constant filtering of the air in your home. The second is that because the air is moving, you have a more even temperature throughout the home. However, leaving your fan on 24/7 is not a good idea. The filter will become dirtier much faster and need to be replaced more often. The cost to run the fan constantly is much greater than simply turning on your HVAC when you need it.

Using the Auto Option for Your Thermostat Fan

Setting your fan to “auto” allows the thermostat to determine when heat needs to be blown into the home. This cuts down on the overall costs of heating your home because the heat will not be blasting all the time. One downside to this option is that the areas located closest to the thermostat will always be warmer than the rest of your home. Rooms that are far away from the thermostat may feel significantly colder than rooms that are closer to it.

The best option to choose when operating the fan on your thermostat is the circulate option. This allows the fan to run for a portion of each hour without overwhelming the system.
