Air Handler

After temp setting is met fan keeps running. If you move setting down one degree (A/C) it will stop. Is this tstat or something else. Just had coil cleaned.

Welcome to the forums.

That's actually pretty strange as usually the AC and fan shut off together.

Based on your turning it down one degree would suggest a thermostat issue.

If the fan is control by a sequencer the fan will run for up to 90 seconds after demand from the thermostat is removed.

Some thermostats have the option to delay the fan as well.

This function can increase the efficiency of the system but will increase the humidity in the space as well.

Did this problem just start?
