đź’ˇ HVAC TECH TIP: High Humidity in Your Home?
If you’re noticing high indoor humidity, one of the first things to check is your thermostat.
Make sure the FAN setting is set to AUTO — not ON.
When the fan is set to ON, the blower continues running after the air conditioner shuts off. This can blow moisture remaining on the evaporator coil back into the home, increasing indoor humidity.
âś… Fan = AUTO
❌ Fan = ON
It’s a simple thermostat setting that can make a noticeable difference in indoor comfort and humidity. Streamline Heating & Air LLC
