The Constant Fan Myth
One of the most persistent myths in home heating and cooling is that running your furnace fan continuously will save you money and provide better temperature control. As your trusted Buffalo area HVAC experts, we’re here to explain why this common belief could actually be costing you more.
Understanding Your Furnace Fan
Your furnace fan, also known as the blower motor, is responsible for moving conditioned air throughout your home’s ductwork system. While it’s an essential component, running it 24/7 isn’t necessarily beneficial.
Here’s why:
1. Increased Energy Consumption
– A typical furnace fan uses 400-700 watts per hour
– Continuous operation can add $20-50 to monthly energy bills
– Modern variable-speed fans are more efficient but still consume energy
2. Additional Wear and Tear
– Constant operation reduces equipment lifespan
– More frequent maintenance required
– Earlier replacement needs
The Better Approach
Instead of running your fan continuously, we recommend:
– Using the “Auto” setting on your thermostat
– Regular maintenance of your HVAC system
– Proper filter changes every 1-3 months
– Professional duct inspection and sealing
The Bottom Line
While it might seem logical that constant air circulation would improve efficiency, the reality is that modern HVAC systems are designed to operate cyclically. Letting your system run as intended will provide optimal comfort while keeping your energy costs in check.
