Why Running Your Fan All Day Is Not Always The Smart Choice

The Persistent Myth of 24/7 Fan Operation

Many homeowners believe that keeping their HVAC system’s fan running continuously will result in better air quality and more consistent temperatures throughout their home. At Jacobazzi, we regularly encounter this misconception during our service calls, and it’s time to set the record straight.

Here’s why running your fan all day might not be the best strategy:

1. Increased Energy Consumption
Running your fan continuously can significantly impact your monthly energy bills, often adding unnecessary costs when the system doesn’t need to be operating.

2. Excess Moisture Problems
During humid seasons, your fan might redistribute moisture back into your home when running between cooling cycles, potentially creating uncomfortable conditions.

3. Shortened Equipment Life
Constant operation means more wear and tear on your system components, potentially leading to premature repairs or replacement.

The Smarter Approach

Instead of continuous operation, we recommend using the “Auto” setting on your thermostat. This allows your system to run only when necessary for heating or cooling, which:

• Optimizes energy efficiency
• Maintains appropriate humidity levels
• Extends equipment lifespan
• Reduces maintenance needs

When you need your indoor air quality addressed, there are more effective solutions than constant fan operation, such as dedicated air purification systems or regular maintenance schedules.

Remember, every home has unique heating and cooling needs. While some situations might benefit from increased fan operation, it’s rarely necessary to run it continuously. For personalized advice about your HVAC system’s optimal operation, Jacobazzi’s experienced technicians can evaluate your specific situation and provide tailored recommendations.

By understanding this common misconception, you can make better decisions about your home’s comfort while potentially saving money on energy costs and future repairs.
