Do you need to replace your AC fan motor?
While fan motors don’t need much, overlooking maintenance can have a serious impact on your air conditioning system and the comfort of your home. Sometimes, replacing the fan motor in your air conditioning system is inevitable, but with routine maintenance, you can prolong the lifespan of your air conditioner.
What should I do if my AC Fan is flat?
If it’s flat, you could narrow down the malfunction to the fan. Fixing this issue as soon as possible is crucial, since having a faulty fan can shorten the lifespan of your AC compressor, resulting in the need to replace both parts. Purchasing a new compressor is substantially more expensive than replacing the fan.
How can I tell if my AC fan motor is bad?
Check the power If you suspect the fan motor is bad, the first thing you should check is the power to the motor and the power to the air conditioning unit. Locate the circuit breaker and ensure it hasn’t tripped. If the power is fine, check to see if there is proper voltage.
Why does my AC Heat fan make a clicking noise?
If your interior AC/ Heat fan (blower motor) is making noise like a card in a bicycle spoke, then you probably just need to clean out the blower motor which is easy and free. Leaves and debris gets in the blower motor and make a clicking noise when the fan hits the leaves.

What should I do if my heater fan switch is not working?
As long as there are no bare wires exposed, reconnect the battery cable and try running the heater fan to see if there is other diagnostic work to be done. If everything checks out, disconnect the battery again, route the switch back through the hole, and attach it with the nut.
How do you set the fan speed on an air handler?
Inside the air handler, usually on a control board (a printed circuit board) there will be one or more switches or little jumpers that the service technician can set to control the fan speed or speeds on the particular air handler. It’s usually a switch or jumper change, or occasionally on older air handlers, moving a wire from one pin to another.
Is there a way to change the fan speed?
Adjusting the fan speed during air conditioner operation can offer several advantages from the standpoints of comfort, humidity control and energy consumption. The fan speed can simply be switched manually or with a special controller. Khattar, Mukesh, and Hugh I. Henderson Jr. “Impact of HVAC control improvements on supermarket humidity levels.”
What happens when your AC Fan is running 24 / 7?
Better dehumidification. When your fan is on “AUTO,” moisture is able to drip from the cold cooling coils and drain outside. When the fan is running 24/7, that moisture doesn’t have a chance to drip outside. Instead, it blows back into your house, and, as a result, your AC then has to work ever harder to suck that extra moisture out of the air.
Is it better to leave the HVAC fan on all the time?
Less frequent starts and stops of the fan can reduce the stress from startup, and potentially help extend it’s lifespan. Leaving the fan on 24/7 ensures cleaner air, as the air is pulled through the filtration or UV light system. This can be better for people with allergies.
