Well, it's getting warm again, and you know what that means: finding issues with your A/C that somehow developed over the winter. I have 0 experience with A/C so I'm just gonna describe whats going on and see if you guys can point me in the right direction. When I turn it on to cool it just blows air at the same temperature of where ever its pulling it from. If I turn it to heat, it still blows just as hot as ever.

I have no idea where to start on this one, so any help would be appreciated.
