Rattling, grinding, or banging noises often indicate mechanical issues. Strange odours could signal mold, electrical faults, or refrigerant leaks. These are problems that need immediate attention.
If parts of your building are too hot or too cold despite thermostat settings, your HVAC system may have airflow or zoning problems requiring expert troubleshooting.
A sudden spike in energy costs can point to inefficient equipment or failing components working harder than they should.
