Which of the following is NOT a typical sign of HVAC system issues?

A uniform temperature across rooms is not typically a sign of HVAC system issues because it indicates that the system is functioning well and distributing air evenly throughout the space. In a properly operating HVAC system, the goal is to maintain consistent temperatures across different areas, ensuring comfort for occupants. When this occurs, it suggests that the heating or cooling is effective, and there are likely no underlying problems with air flow or temperature regulation.

On the other hand, inconsistent airflow, visible water leaks, and strange odors are all common indicators of HVAC problems. Inconsistent airflow can suggest blockages, duct issues, or problems with the fan or blower. Visible water leaks might indicate refrigerant issues or condensation problems, which can lead to significant damage if left unaddressed. Strange odors can be a sign of mold, burned components, or other malfunctions within the system. All of these are typically symptoms of an HVAC system that requires attention or repair.
