Question
I recently changed my heater core due to coolant leaking. Now  I'm getting heat coming from the bottom of dashboard, non-stop as if the climate control is not working. The faster I go, the more hot air I fell or getting hotter. When I turn the A/C on, it only blows hot air as well. Do I need to recharge the freon? Please help and thank you in advance.

Sorry, I forgot to include in first email. This is for a 1996 Cadillac Deville

Answer
IS or HAS the CHECK ENGINE light ever illuminated on the dash ?.

As long as you did NOT drain the A/C FREON from the A/C system there is no need to recharge it. You most likely do not have something put back and or adjusted correctly when you changed the heater core.
