Most thermostats have a setting for the fan called, "manual". That keeps the fan on continuously. The electronic thermostats can fail in a "fan on" condition. That would require a new thermostat. I also saw one air conditioner with a fan relay welded "on" by electrical surge. That would require a new relay.

jbrown - Hot air rises, Cold air falls. If you have ceiling fans upstairs, turn them on to run counterclockwise at highest speed you can stand. Make sure all the windows are closed upstairs. The ceiling fans will help to keep the cool air upstairs and pull some from downstairs.

If you don't have ceiling fans, invest in a box type fan that you can place at the head of the stairs (that's the top of the stairs) run it on HIGH and it will act like an exhaust fan, by pulling cool air upstairs. It may take a while, but it will help cool the upstairs to some degree.

Hope this helped you. Please let me know. Thanks.

Is this a new hvac system? A new furnace can work differently than your old one. Does it shut off after a minute or two or continue to run? If it continues to run then call that professional back and let him fix it. If it shuts down after a minute or two then it is a feature of the new thermostat to squeeze all of the cool it can from the a/c coil and ductwork.Some of them have settings that you can adjust for blower delay on and off, read the manual that came with the t-stat and see if it does.

Bryant central air unit fan doesn't stop.


This is a condenser fan and as long as the A/c unit is in cool mode, this fan will run. The only time it should shut off is when temperature setting is satified and the unit shuts off.

Fan is still running in house constantly


Check your wall thermostat to make sure the "fan" switch is in the "auto" position. If it is set at the "on" position, the indoor fan WILL run continuously. Not really enough info as to what type of split system you have. Gas? Electric? Heat pump? Oil? Wood? Newspapers? See what I mean? Is it variable speed? Do you have a "special" thermostat for certain operations? Does your system incorperate inverter technology?

Ensure you don't have a short in your therm wires. Disconnect them, if the furnace continues to run, you have a lockout problem at your furnace. When the motor on the fan fails, it wont run. Check for led codes on the control board. If you don't have led codes, turn off the power to the furnace at the breaker, and watch the unit. If nothing happens, connect the thermostat. If nothing happens still call for heat. Let the therm run through it's cycle, and if the bower runs continuous again, let me know we can walk through that situation.
