Loud in which way? If there is a rumble type noise, there could be some debris in the blower fan. Have seen over time leaves, foam, parking pass/receipt, dog food, rodents, grass, etc...

Sounds like there is some debris in the fan, it would need to be lowered and inspected. Another possibility is a broken impeller, but they are pretty tough.
