1. Unusual Noises Coming from the Unit

Strange sounds like grinding, banging, or hissing often signal internal damage or wear. These noises shouldn’t be ignored—they can indicate failing components or airflow blockages.

2. Inconsistent Temperatures in Rooms

If certain rooms are too hot while others are cold, it might mean your system isn’t distributing air evenly. This usually points to ductwork issues or a failing thermostat.

3. Rising Energy Bills Without Increased Usage

An inefficient HVAC system works harder to maintain comfort, which directly affects your electricity costs. If your usage hasn’t changed but bills have, service is needed.
