plug sound coming from 1 and 2 steps from heating

friends, we changed 206 pressure pad, since my father could not have a license, I did not stop because I did not have a driver's license exam. ?

I have it too. Apart from the sound of air blowing, there is another scabies voice, yes. It's the same as you described. I didn't think it was a problem, but follow up ..

When the AC button is pressed, that is, when the air conditioner is activated, a plug is heard first and then it is normal. Because the air conditioner operates with gas, this is the condensation sound. But if it does it in the heating mode, you can have it checked, or it may be from a different location.

This sound comes in the heater, not in the air conditioner.

Me too, from the heater. Especially it is heard more in the 1st stage. A lousy voice sounds. I don't have a problem like water reduction.

I have a sound like that, but it happens when I turn on the cold air conditioner. I think his engine is broken. I had it done, it had improved again.
