I would like to take a look at that myself; however, call a hvac technician to take a look at it, as soon as possible.
Your central air conditioner may make a loud noise when it comes on. This is because it may have a leak somewhere in the system.
Loud noise is not a good description. If its a loud squeal turn the air conditioner or defroster off. If the squeals goes away the compressor or the clutch for the air conditioner compressor is locked up.
Airflow improperly set (too high) or the most common undersized ducts.
Often when a vehicle air conditioner gets loud, the problem is due to a belt. You should take the car in to have the belt checked.
Seems Compressor need to be changed.
Loud
It would be loud and annoying.
your engine is loud because, the fan makes that noise
In my case, the loud noises are me screaming when I fall.
Loud things starting with K: klaxon
Because while your air conditioner is activated the air from outside is coming in being purified and is then released so its like a vacuum of some sort!
More vibrations....
