In Michigan specifically: humid summers. Basement moisture and summer humidity affect comfort. Blocked vents: Snow can cover PVC intakes and exhausts, shutting down high-efficiency furnaces.
Michigan licenses mechanical contractors through the Department of Licensing and Regulatory Affairs (LARA). Ask any contractor for their license number before work starts, and expect a written price for AC Replacement & Installation.
