Good for areas of high moisture: When the humidity is high, the “circulate” setting could give you relief. It can also work to combat mold growth. Regulates hot or cold spots: Lowering or raising the temperature on the thermostat might not be necessary to keep it cool and cozy in your space.
Setting your thermostat to auto will allow your system to be more energy-efficient since the fan only runs when the system cycles on, not continuously. Typically, the fan will turn on 30 to 60 seconds after a heating or cooling cycle starts and then turn off a minute after the cycle ends.
“Circulate” Mode
If you have this setting, we recommend using it as often as you can because it's a good money-saver on hot days.
When you choose “auto,” the fan only runs when your air conditioner or furnace is running. The “circulate” (or Circ) setting will usually make the fan run about 35% of the time. The fan will operate when the fan is on and about 20 minutes of every hour otherwise.
So which was should your fan go in the winter vs the summer? For colder months, you want your fan to spin clockwise (reversed). And you should run it on low. This creates an upward draft that brings the room air up and pushes the hot air down and out.
The circulating fan feature allows the fan to circulate air when the system is not running. A percentage is selected to indicate how often the fan should run each hour. The circulating fan feature can only be programmed at the thermostat in 5% increments from 10% - 100%.
Which way should a ceiling fan turn to keep you cool in the summer? During summer months, your ceiling fan blades should be set to spin counterclockwise. When your ceiling fan spins quickly in this direction, it pushes air down and creates a cool breeze.
If you wonder, “How long should my HVAC fan run per hour?” then the answer is between ten to 20 minutes for two or three cycles. This works best when your home has a mild outdoor temperature. When temperatures shift strongly towards 0 or 90 degrees (heating or cooling), you will need to run the fan longer.
On: Fan is always on. Circ: Fan runs randomly about 33% of the time. *The circulate option that allows you to set the fan to run a certain amount of time per hour.
Since the AUTO setting means the fan is only engaged when the system is on, rather than constantly blowing, AUTO is the most energy-efficient option between the two settings.

Some homeowners naturally worry about the risks of a breakdown if they run the fan all the time, but this will not be a concern for you if your HVAC system was properly installed and maintained.
They help improve comfort year-round by effectively circulating air throughout a room. Summer Use: Run ceiling fans counterclockwise to create a cooling breeze. Winter Use: Reverse the direction to clockwise and set to low speed to circulate warm air from the ceiling down to living spaces.
Keeping your fan on AUTO is the most energy-efficient option. The fan only runs when the system is on and not continuously. There is better dehumidification in your home during the summer months. When your fan is set to AUTO, moisture from cold cooling coils can drip and be drained outside.
Thermostat Operation
The smaller the difference between the indoor and outdoor temperatures, the lower your overall cooling bill will be. You can easily save energy in the winter by setting the thermostat to around 68°F to 70°F while you're awake and setting it lower while you're asleep or away from home.
First, check your filters and coils for dirt and debris that may be impeding airflow. Once you've cleaned the filters and coils, run the air conditioner with just the fan so that the ice accumulation can melt off. If the AC still doesn't blow cold air, it could be that refrigerant levels are too low.
Choose "AUTO" for energy savings and "ON" if you want constant air circulation or improved air filtration. Temperatures can soar or plummet depending on the time of year. Throughout the year, it is important to have reliable heating and cooling systems in order to keep your home supplied with cool or warm air.
While we typically don't think of winter as a humid time of year, poor ventilation in the home over the heating season can cause an increase of humidity inside the home, which causes indoor air quality issues such as pollution concentrations to grow.
The circulate setting turns on the fan for some time every hour so the air in your rooms is moving. It will do this regardless if the heating/cooling is on. With this setting off the fan only turns on to provide heat/cold air.
This is the setting used to move air in your application all the time instead of when the system is running. The Circ (Circulate) position, if available, will run the fan approximately 35% of the time, roughly 20 minutes each hour, minus any time the fan is already running with the heating or cooling system.
Air flowing freely throughout your home helps to regulate temperature, prevent buildup of particles and mold, and it makes breathing easier for everyone in your family. Also, if you enjoy cooking or use a lot of hobby supplies (glue, spray paints, epoxy, etc.), good air circulation can help dissipate odors and fumes.
On an average summer day, a general guideline is that your AC should operate between 12 and 16 hours. However, several factors can influence this, including the outdoor temperature, desired indoor temperature, the size and type of your unit, and your home's energy efficiency.
Changing the direction of a ceiling fan can significantly impact room temperature and overall comfort. During the summer, setting the fan counterclockwise creates a wind-chill effect. This breeze makes the room feel cooler, allowing occupants to rely less on air conditioning, which can lead to energy savings.
You should place outward-facing fans on the warmer side of your home to blow the hot air out and inward-facing fans on the cooler side to draw cool air in, says Barry Jacobs, vice president of product development at Comfort Zone, a home environment product company.
Consider fan placement
Adjust your fan so it faces the opposite wall from where you'll be located and make sure there are no obstructions, meaning the air can bounce off the wall and cool the space overall. It is recommended that you place your fan on the floor and point it upwards since heat rises.
