Allowing the fan to run uninterrupted, there is a more even distribution of warm or cool air circulating through your home. This will help reduce hot or cold spots within your home. There could be reduced stress on the fan from less frequent starts and stops, which could potentially help extend its lifespan.
What is fan circulate setting?
Most new thermostats have a “circulate” option that allows you to set the fan to run a certain amount of time per hour. This evens out hot and cold spots, uses your high-efficiency filtration or UV system more effectively, and keeps energy usage from going through the roof.
