Funny noise

[r2.ha]

Hey I don't know if someone will know what's wrong but I just had my accessory belts changed but ever since then everytime I want to turn on my heat or ac I get a high pitched squealing sound coming from my engine bay

[J-hop]

could possibly not be tensioned properly? check the deflection of the accessory belt when you press on it, shouldn't be much.

New belts can stretch and loosen off. Thus requiring retensioning.

If a shop replaced them, call them and ask for them to be retightened.

I have the most grief from Bando brand belts for some reason.

I usually have to retighten them after 10 minutes of run time.
