Question:

what's the difference between a fan motor and a blower motor in an AC/Furnace unit?

my AC unit at home is not working. I called two companies and they are giving me different quotes and fixing different things? Apparently the motor is not working, but one wants to replace quot;fan motorquot; and quot;blower wheelquot; and he quoted me $1450; another company said he needs to replace the quot;blower motorquot; and the bill for that would be $800. Both of them said the fan/motor aren't working and the unit does sound wrong when it's running.... but why are they recommending changing different things? The first company already charged me $200 for changing the capacitor, and that worked for a few days, but now i'm being told that it's the fan that's not working.... help please.....

Answer:

Where do you live those prices sound like Beverly Hills, are your neighbors Tom Cruise and Brad Pitt on the other side. Tops pay $350-400 for a new blower, you can buy them on OKorder for $150 and its literally just 3 screws and a clip and you just saved a ton.
Blower Motor Fan
$200.00 for a $8.00 capacitor is a lot of money. It don't take but 5 minutes to change any capacitor. The furnace fan motor operates in the cooling and heating modes. If the system is moving air then your fan motor is fine. If your in the cooling mode and the air is not getting cold. The condensing unit outside has a fan and that may not be operating.
The fan motor and blower motor are one in the same, the blower wheel is a separate item attached to the blower/fan motor. It is a good idea to have them replaced at the same time if the unit has any age on it, but it's not always needed. If the unit was vibrating BEFORE the motor went out then that might indicate that the blower wheel was out of balance and ruined the bearings in the motor. Those prices sounded pretty high, but I guess it varies from area to area.
