What is a common symptom of a malfunctioning HVAC system?

A common symptom of a malfunctioning HVAC system is inconsistent temperature or airflow. When an HVAC system is operating normally, it should maintain a consistent temperature throughout the space it serves and provide steady airflow. If there are fluctuations in temperature or if certain areas of a building receive little to no airflow, it is indicative of potential issues, such as a malfunctioning thermostat, clogged ducts, or problems with the system's components.

This symptom can lead to discomfort for the occupants and may also signal underlying mechanical issues that could become worse if not addressed promptly. Identifying this symptom is crucial because it often requires timely intervention to restore the system's efficiency and effectiveness, ensuring a comfortable indoor environment.
