I have a Intertherm electric furnace, I live in a mobile home that we just purchased Used. As of now the only air conditioning we have are window unit air conditioners.. My question is.. There an air conditioner unit we can add to the unit we currently have, for air conditioning? I have never lived in a mobile home.. So this is all new to me.

Sure,, that's the way is done. Even in a house, ac is added to a furnace., just call several local HVAC contractors and get some estimates, choose wisely,ask around for advice on reputable contractors with referances
