When you are selecting the ON or AUTO feature on your home’s thermostat fan setting, you are actually selecting whether you want the fan to be set to run continuously or only when the heating system is in use. Your furnace will run as needed to keep your home the set temperature, but whether you keep the fan set to ON or AUTO is a choice of cost vs. comfort.
At Rick’s Heating & Cooling, we are always looking out for residents within the Morrow and Lebanon, Ohio area when it comes to their heating and cooling decisions. To allow you to make the most informed decision for your home’s HVAC system and indoor air comfort, let’s break down the advantages and disadvantages of each setting.
Leaving the Fan Set to ON
If you set the fan to ON, you will likely experience better indoor air quality throughout your home. Because the fan cycles constantly, it:
- Is constantly filtering the conditioned and heated air throughout your home – this can help decrease allergies since dust and other particles are filtered out faster
- Will keep the temperatures consistent room to room – some homeowners complain that some rooms of their home are too cold during Ohio winters. If you’re fan is constantly running, it can do a better job of distribution the heat throughout the entire house
Leaving the Fan Set to AUTO
If you set your thermostat to ON, you will most likely pay more month to month on your energy bills. If your fan runs constantly, your monthly heating bills will be higher. The AUTO setting can cut some of that cost. Your ductwork fan will still run when the furnace is heating your home, but will stop once the rooms have reached the set temperature.
Leaving the fan set to AUTO will:
- Save you money
- Be more energy efficient
- Give your system a break (which can prevent possibly repairs from overuse)
- Lengthen the lifespan of the fan’s motor
Not only will an AUTO setting save you money month-to-month on your energy bills, but it can save you from paying for a new motor or other repairs that come from overuse of the fan and your HVAC system.
You don’t have to sacrifice indoor air quality with the AUTO setting either—changing your air filters regularly and having your ductwork cleaned every few years can also improve your indoor air quality and decrease allergies caused by the vent systems. Many HVAC professionals recommend using the AUTO setting.
