Centralized Air Conditioner System On and Auto Modes

Your Air Conditioner System does not only produce cold air, it also uses a fan to circulate the air in your home, allowing you to enjoy cooler temperatures in every room.

There are usually two fan settings: ‘On’ and ‘Auto’ which can be confusing to homeowners who aren’t familiar with how their Air Conditioner System works.

The below explanation of an ‘On’ and ‘Auto’ settings will help you better understand how to set up your AC fan for maximum comfort and efficiency.

‘On’ means that the fan is constantly running, pushing air through the house whether the AC is currently in cooling mode or not.

‘Auto’ runs the blower only when the air conditioner and furnace can make the air cold and warm respectively.

‘Auto’ setting benefit:

The primary advantage of the “auto” setting is that it uses less energy than the “on” setting because the fan only runs when your home is in a heating and cooling cycle. This also means that your fan motor will last longer before you need to service it because it’s not running all the time.

‘On’ Setting:

Using the fan more often means it will break down more often. Furthermore, your electricity bills will be higher. Using the fan when the Air Conditioner System isn’t cooling can also draw humid air back into the house, which can counteract some of the comfort you gain from the continuous air distribution. But ‘On’ setting does have its advantages. The fan will circulate air more evenly throughout your home, making you more comfortable. Running the fan more often means that filter is catching more airborne pollutants that agitate allergy and asthma symptoms.

The Choice Is Yours

Overall, it is up to you whether you prefer saving money on your electric bills or keeping your ventilation system running all the time. If you need more help deciding what to do or getting your fan set up properly, or if you would like a heating and cooling system serviced or installed in your home, contact DeMark Home Ontario, your heating and cooling expert.
