Should I keep my fan on AUTO or on?

Keeping your fan on AUTO is the most energy-efficient option. The fan only runs when the system is on and not continuously. There is better dehumidification in your home during the summer months. When your fan is set to AUTO, moisture from cold cooling coils can drip and be drained outside.

What's the difference between auto and fan on?

Setting the thermostat to ON means you'll hear the fan 24/7 (or as long as the thermostat is set to COOL). In AUTO mode, you'll only hear the fan as it's pushing cool air into your home. If you have a newer high-efficiency system, this will not apply to you as the fan noise is minimal in newer systems anyway.
