We offer personalized service and can help determine what’s best for your needs during a high-performance tune-up.
Understanding Your Furnace Fan
The fan setting on your home’s thermostat plays a crucial role in the operation of your central furnace, air conditioner, or heat pump. It works in conjunction with your home’s ductwork to distribute conditioned air throughout your living spaces, from heated air in the winter to cooled air in the summer.
The answer to whether you should leave your fan on continuously depends on various factors, including:
- Your home’s layout & insulation
- Your comfort preferences
- Indoor air quality concerns
- Energy efficiency goals
- The age and efficiency of your HVAC system
Running the Fan Continuously
When you set your thermostat fan to “on,” it means the fan will run continuously, even when your furnace isn’t actively heating. This offers benefits for your home such as:
- Improved air circulation throughout your living spaces
- Enhanced indoor air quality by filtering air continuously
- Reduced motor stress by minimizing frequent starts and stops
Using the “Auto” Setting
When your thermostat is set to “auto,” the fan only runs when your furnace is actively heating. This setting offers benefits including:
- Increased energy efficiency by running the fan only when needed
- Extended filter life as the fan operates less frequently
- Lower energy bills due to reduced electricity usage
