Strange sound coming from the vents / Airco related

joshiba · 05-20-2020, 05:23 AM

Hi guys,
Last week after my airco did not blow cold air anymore i had it refilled.
For 3 days cold air came out like normally.
This morning however this noise came out of the vents with the airco on.

Do any of you know this sound?

I listened to your video and that sound is the very same sound I heard when my refrigerant was nearly depleted. Is it possible that when your AC was topped up it was not sealed properly and you are running out again?

You should do a vacuum test to see if
1. It has pressure (and if not)
2. Can hold pressure
You would need an a/c manifold. ~$50
And an a/c vacuum pump ~$70.
Can be bought from hft. Very easy to do
Then determine if you have a leak somewhere
I read that the f10 was notorious for the condenser to leak. Mine leaked but only after hitting a raccoon on the highway. It punctured mine. I have since replaced it and recharged my system. All good.

This. My condenser had to be replaced as it indeed was causing my leak. All good so far, three years later.
