It is in the Beverly Glen/Bel Air area. 

Air leaks around these openings are often pretty easy to improve.

I do have an excellent cleaner but the pricing isn’t cheap.

Last weekend it stopped to work again but heard loud sounds in the air handler.

Opportunity cost is the name of the game, in a fiat system where we create money out of thin air; Money now is more valuable than money in 30 years.

@John Underwood @Zambricki LiFor those of you who do not use third party management software, are you able to have Airbnb/VRBO automatically alert your cleaners of new reservations or at least share a calendar with them? 

I had a similar experience with birds nesting inside my fresh air exchange vent to an HVAC system.   

Remember AirDNA includes the cleaning fee in their revenue calculations - you will have to pay the cleaners - this is a significant expense. 

In this case, it was considered a storage space rather than sq ft under air.

They had to wait for my cleaners to get it all done so they had to hang out until after 4pm.After that I just send the address and check in instructions 2 days before arrival via text.
