- Unusual HVAC noises: Banging, grinding, squealing, or rattling sounds.
- Inconsistent temperatures: Difficulty maintaining the desired temperature may point to issues with airflow and the thermostat.
- Higher energy bills: A sudden increase in energy costs may mean the HVAC system is working harder because the parts are wearing out.

- Frequent cycling: An HVAC system that turns on and off repeatedly may have thermostat or refrigerant issues.

- Water or refrigerant leaks: Leaks can indicate system damage.
