AC - fan only blows hard, when ac is on it blows weak

I have a house that I rent out to a family. New coil was put in last fall, they are having problems again. They say that they can feel a little cold air coming out of the vents but it is not blowing out like it should, as a result the house is very warm. They said when itís on fan only it blows fine. Just when itís set on AC it gets very weak, does this make sense to anyone? Anyone know what the problem might be? I already called the professionals and they didnít find anything.

Welcome to the forums.

We need to know the make and model of the air handler.
Is it a gas furnace with split air ?
Is it a heat pump ?
We need details.

A gas furnace would have several blower possibilities.
