Travelling & experiencing a high pitched sound coming from the air vent

I cannot wait for my upcoming trip where I will be going to see two unusual countries, exploring & going backpacking for 3 weeks.

It is something that I’ve always wanted to do & I have saved up enough money to finally do this, obviously I have a easily strict budget & I cannot stay at luxurious places so I am staying at hostels & cheap hotels.

I shall never forget that this one hotel that I was staying at for 2 mornings was not easily luxurious. I could hardly sleep due to a easily loud noise coming from a vent. I got so sick & tired of the noise that I reached out to the main desk… A afternoon later the loud noise from the vent was finally fixed. While I was just about getting ready to leave a heating & cooling professional came & stated that the reason why the return vent in my room was making such a high pitched type of sound was that there was a lack of return air. The heating & cooling system needs to pull more air so that the pressure & velocity increases & this also increases the sound level & that’s what I was hearing. If there was more return air then the air pressure would drop & the HVAC system will not have to work as difficult & the sound would minimize. The heating & cooling professional was seriously know-howable & I was impressed on how much he knew. I’m blissful that the issue was fixed even though I was no longer going to be staying there because I had to travel & go to a current city. At least the next guy who would be staying in this room would not have to experience the high pitched noise.
