Low AC freon causing belt chirp?

[mclasser]

I made a post the other day about getting an AC recharge in my sig Accord since it doesn't blow as cold as before.

I've recently noticed the Alternator/AC belt starts chirping the moment I turn on the AC. When the compressor cycles off, the chirping disappears. There is no noise when I have the AC off and there is a load on the alternator, i.e., headlights on. The belt tension and condition are fine. Could low freon and constant cycling on/off of the AC be causing the belt chirp?

old/loose belt will cause chirping.

When compressor kicks in, there's load to the belt driven system thus the chirping.

Check for belt tension and tighten it up if possible. If chirping persists, replace the belt.

Q.

No. Overcharged may though. Probly just needs a new belt

+1. Overcharge will not cool as well. Actually having working fluid will increase load and can cause chirping of a weak/old belt.
