Can a bad blower fan call for heat and air?
But I don’t understand how a bad blower motor would call for heat and air at the same time. A bad blower motor ought to mean that air stops being blown through the ductwork. The absence of cooled air would be sensed by the thermostat set in cooling mode and the TT would never be satisfied – it would keep calling for cooling.
Why is the air coming out of my fan not cool?
David those explanations about A/C troubles leave me confused. If the air coming out of your supply registers is not cool the system is not working and it’s more than a duct problem. If there is no air coming out of the supply registers that’s often a fan or filter or duct problem, or a cooling coil blocked by ice.
Where does a ceiling fan need to be in order to have good airflow?
Your ceiling fan’s blades need to be at about 10 to 12 inches from the ceiling to produce the best airflow. Unless it is a hugger ceiling fan that is designed to be closer to the ceiling, if your typical fan is too close or too far from the ceiling it won’t move as much air.
When does a blower fan cool down the heat exchanger?
In the ARTICLE INDEX you’ll see articles on FAN CYCLES DURING HEAT and FAN CYCLES AFTER HEAT STOPS (those are approximately the titles) where you’ll find useful diagnostics for the case you describe @Steve, So could you tell me what control the blower to cool down the heat exchanger temperature?
Why does my air conditioner fan not come on?

What should I do if my blower fan wont come on?
You will need to test with a voltmeter and see if your fan motor is getting the required 110 to 125 volts AC out of your control board to start the motor. I would suggest setting your thermostat to the “Fan ON” position. You should be getting 120 volts out of the control board.
What does a blower motor do in a HVAC system?
The blower motor is a component in your HVAC system that blows the conditioned air through the vents in your home. It takes the cool air created by your air-conditioner and circulates it throughout your indoor space to ensure that the temperature reaches the level dictated by the thermostat.
Why does my blower only work on high speed?
If your blower only operates on its highest speed, chances are you have the series type of blower motor resistor. This is the most common failure mode. To repair the problem, simply replace the resistor block.
