Simple Tip for Fresher Indoor Air

REDWOOD CITY — When your HVAC system is running, it’s not only heating or cooling your home, it’s also circulating the air. That’s why in mild seasons like spring (when your system is seldom in use), your indoor air can become stagnant due to a lack of circulation. To address this, run your system on the “fan only” setting at regular intervals—ideally 10 to 15 minutes every hour. If you don’t want to do this manually, consider investing in a thermostat with the capability to program “fan only” operation. This will allow you to enjoy fresh, well-circulated air without having to continually adjust your thermostat.
