A recent local news segment by WATE 6 featured a technician from Rocky Top HVAC to help explain common heating and cooling issues homeowners face, especially during periods of extreme weather.

The interview focused on how HVAC systems operate under stress, what typically causes failures, and what homeowners can do to avoid unexpected breakdowns.

Early in the segment, the technician explains that heating and cooling systems are more likely to fail when outdoor temperatures are at their highest or lowest. During these times, systems run longer and more frequently, which can expose worn components or existing issues.

Older systems and units that have not been serviced regularly are especially vulnerable when demand is high.

During the interview, several common warning signs are discussed, including:

• Unusual noises coming from the system

• Uneven temperatures throughout the home

• Rising energy bills

• Systems that struggle to keep up with outdoor conditions

According to the technician, these signs often appear before a complete system failure and shouldn’t be ignored.

The segment also highlights the importance of routine inspections and maintenance. Preventive service can help identify small problems—such as airflow restrictions or failing parts—before they turn into larger, more expensive repairs.

Maintenance is especially helpful when done ahead of peak heating or cooling seasons.
