That noise might not be a ghost, but it’s worth paying attention to. 👻 New rattling, banging, or squealing gives your service team something to investigate.
Before you call, here’s what’s helpful:
• Note the exact location, including the floor, suite, or nearest vent.
• Record a short clip from a safe distance.
• Mention when it happens and whether other rooms or tenants are affected.
• Report changes in heat, airflow, water pressure, or any visible leaks.
Tenants: send those details to your property manager or building’s maintenance contact. Leave mechanical equipment and controls to authorized personnel.
Property managers: sharing recent service history and arranging equipment access can help your technician investigate efficiently.
CAON can assess your commercial HVAC, heating, and plumbing systems, explain what’s happening, and recommend repairs or preventative maintenance.
You bring the details. We’ll bring the expertise. Call 403-279-6641.
