Solution: Verify that the thermostat is set to the appropriate temperature and mode. Replace the batteries if the thermostat display is blank or unresponsive.

3. Inspect Vents and Ductwork

Issue: Blocked or obstructed vents and ductwork can restrict airflow and impact the system's ability to heat or cool the space effectively.

Solution: Ensure that all vents are open and unobstructed. Inspect the ductwork for leaks, gaps, or blockages that may hinder airflow.

4. Listen for Unusual Sounds

Issue: Unusual noises emanating from the HVAC system can indicate potential mechanical problems or component failures.

Solution: Listen for any abnormal sounds and investigate their source. Contact a professional technician if you suspect significant internal issues.

5. Address Refrigerant Leaks

Issue: Refrigerant leaks not only reduce system efficiency but can also pose environmental and health hazards.

Solution: If you detect refrigerant leaks, immediately shut down the system and contact a qualified HVAC technician to locate and repair the leaks.
