Bird In HVAC

[Kevin Coleman]

I have a 3 unit property in Chicago. The tenants stated they heard birds in the vents. I went there yesterday and heard what they were talking about. There are definitely bird(s) in the HVAC. I specifically heard and briefly saw a bird in the return vent.

Anyone had this issue before? I'm not sure who I should reach out to? HVAC company?, roofer to see if they are getting into the exhaust vent on the roof? etc
