Could that be the issue?

thanks

Describe the type of sound? Rattling? Loud humming? Screeching?

The accepted rate per ashrae is 25% of the volume of the home per hour. In really tight homes they introduce outside air to purge out indoor pollutants. Your leakage rate can be calculated by data logging co2 in the home and outside the home. Wind and leaky ducts are the main source of leakage in your home.

thank you so much!!!
