AC not moving any air

Whats up guys.


My home AC just decided to quit right before the 4th.

The compressor is still kicking on, the line going into the house is frosted over so i have it turned off for now.

The unit in the attic is on, everything seems like its running fine, except.... no air is coming out of the vents, anywhere in the house. all filters are relatively new as well

the only thing ive noticed is there is what looks like a little electrical fan on the side of the unit in the attic that is not kicking on, other than that... im lost.



any help would be appreciated.

Sounds like the blower has gone out.... or the start capacitor for the blower. Has all of the ice defrosted on the lines and on the evaporator coils?

Welcome to the forums.

That unit in the attic is just AC or is it AC and heat ?

That fan your are describing sounds like the draft inducer blower which is only used to exhaust hot gas from a gas furnace.

There is a big blower inside that unit......you need to see if that is running.

A make and model of the furnace would be helpful too.

PJMax is correct. There should be a larger fan that is positioned just before the heating unit. It will be past where the air comes into the unit. (just past the filter, unless your return filters are at the return vent instead of at the ac unit).

thanks for the info guys, i got it figured out.

there was a huge filter right before the... big fan in the attic, that was completely plugged off and not allowing any air through.

it was supposed to be removed bofore we bought the house last year since there are numerous ceiling filters throughout the house. oh well

Thanks guys
