Dude\ girl it's pretty obvious that you need to clean the dust off of the fans vent whatever
You Said That:
1. the fan had never been cleaned
2. it's caked with dust
3. There's a high pitch sound coming from the vent during use
4. and it heats up very quickly

A. you need to clean it asap monthly or every 2 months because that fan could get dusty over time and could catch fire. If your not really sure what to do just call the HVAC Service .
