- Short Cycling: If the heat pump is turning on and off more frequently than usual, it could be due to a malfunctioning thermostat, a faulty control board, or even an incorrectly sized system.
- High Energy Bills: An unexpected increase in your energy bills can be a symptom of a heat pump working inefficiently due to issues like dirty filters, leaks, or mechanical failures.
- Ice Buildup: Ice on the coils or the unit itself, especially during heating mode, could mean there's a problem with the defrost cycle or refrigerant levels.
- Poor Airflow: Weak airflow from vents might suggest problems with the blower motor, air ducts, or filters.
- Thermostat Issues: If the thermostat is not responding correctly or displaying incorrect readings, it might not be communicating effectively with the heat pump.
