Many homeowners believe that keeping their HVAC system’s fan running 24/7 will improve air quality and save money. At A-All Temp Heating & Cooling, we frequently encounter this misconception during our routine maintenance visits, and it’s time to set the record straight.
The Fan-Running Myth
The belief stems from the idea that constant air circulation will:
• Keep temperatures more consistent
• Filter air more effectively
• Reduce energy costs
The Reality
Continuous fan operation actually:
• Increases energy consumption significantly
• Can raise indoor humidity levels
• Leads to more frequent filter replacements
• May cause premature wear on system components
What’s The Better Approach?
Instead of running your fan continuously, we recommend:
1. Using the “Auto” setting on your thermostat
2. Changing filters regularly
3. Scheduling seasonal maintenance
4. Installing a programmable thermostat
The Cost Factor
Operating your fan continuously can add $20-$50 to your monthly energy bills. This extra expense provides minimal benefits compared to using the standard “Auto” setting, which runs the fan only when heating or cooling is needed.
Remember that proper maintenance and smart operation of your HVAC system will always yield better results than quick fixes or misguided practices. If you’re concerned about air quality, consider adding an air purification system instead of relying on continuous fan operation.
