When to Use Your Thermostat’s Fan in Longwood, FL
Your thermostat has two settings that dictate how your HVAC system’s fans will operate: “auto” and “on.” When set to “auto,” the fans run only when heating or cooling is actively needed in your Longwood, FL, home. In contrast, the “on” setting keeps the fans running continuously. While “auto” is generally the better choice, there are specific situations where switching to “on” might be beneficial. Let’s explore when that might be the case.
Improving Indoor Air Quality (IAQ)
While your HVAC system’s fans are on, they will continue to suck in air and push it through your system’s filters, thus removing at least some pollutants from it. Switching your thermostat to “on” mode for a while may thus improve your indoor air quality. For optimal results, you may want to use this in tandem with some air purifiers.
When Outdoor Temperatures Are Comfortable
Since the winters in Longwood, FL tend to be mild, you may not always need your heating system to be at work. Leaving the fans on may filter your air without ruining your comfort.
Smoothing Out Hot or Cold Spots
Instead of heating or cooling your home evenly, you may sometimes discover that your HVAC system has left a series of strange hot or cold spots throughout your place. Though issues like spotty insulation and leaky ductwork may sometimes be causing this problem, the most common explanation for it is that your HVAC system is simply too large for your home. If this is the case, you will almost certainly notice it short cycling as well.
Ultimately, the only lasting solution to this problem is to replace your HVAC system with a smaller one. However, while you wait for the installation crew to arrive, switching the fans to “on” mode may provide some temporary relief. By circulating treated air, the fans may even out some of the hot or cold spots.
