Using RF wireless receiver to get input data form air conditioner remote

Greetings,
considering I'm quite newbie with Arduino and totally with the infrared technology, my project is interfacing infrared commands sent from my air conditioner remote to the device by using the RF Wireless Transmitter & Receiver kit, in order to send commands directly from my Arduino.
My idea is getting all commands from my remote with the receiver for then to put them in the transmitter code.
I followed the instructions on the link above and set the receiver and transmitter. It actually works, but when I disable the transmitter and try to send commands from my remote, the receiver doesn't get them.
I verified the sensors and the remote itself have the same frequency (433MHz):

Maybe they use different protocols but I don't know what to do in that case or if it is possible to change the receiver settings.
Any clues?

Lots of clues, but a block diagram of what you are trying to accomplish and how you are connecting things would sure help.
