AC Vent making noise
My AC vent is making a whistling like noise.
Any ideas of the cause? My thought is that there are too many vents
closed (1500+ sf + the garage vents, and at least 4 vents are closed).
Could it be something else?
The compressor and stuff sounds normal, but where the cold air comes
out it's just very loud. Is it safe to leave running?
