Battery was low but I started the car and had it charged, but the heat from vents when I turn heat on is not really really hot, it is warm, but not where I think should be. Only code I saw was for intake air leak which I doubt has anything to do with it.Coolant was a bit below minimum so I added some and topped it off

It sounds like the heater core is clogged or the coolant is low which will cause this problem as well, here is a video to go over which can help you fix it or get us started on what the problem is not. Please go over it and get back to me.
