Should the fan be on when the heater is 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.
At what temp does AUX heat come on?
Auixiliary Heat will turn on automatically when heat can no longer efficiently transfer heat from the outside air to heat pump. This is when the outside is around 35-40 degrees and the indoor temperature is around three degrees cooler than the thermostat setting.
Is it better to have a fan or an AC?
Although air conditioners do have a “fan only” mode, usually it’s simply not helpful to cool you and your room like a traditional fan can. That’s because (1) the built-in fan has a lower airflow rate than those you buy and (2) they can’t be adjusted to blow air directly where it’s needed for effective cooling.
How to know if your air conditioner is working properly?
Check all of the heating and cooling controls to be sure that they are set properly and working normally. The thermostat is set to COOL, FAN to AUTO or ON, HEAT to OFF, and the set temperature on the thermostat is set below room temperature (if you want cooling).
What does it mean when air conditioner is only powering the fan?
I measured and recorded data for these settings for comparison in the table you see below. “Fan only” means the air conditioner is only powering the fan and isn’t actually cooling the air. While that’s a feature on many air conditioners, it’s not typically used often.
Can a blower fan work only when the thermostat is set to fan on?
Fan will work only when thermostat set to fan on. Thank you for the question, Anon, as it’s a common A/C, or heating fan operating problem that needs to be understood: I put it as “The blower fan runs only in the MAN-ON switch but won’t run on AUTO”.
