Gibbons Engineering Group has highlighted the effect that dirty cooling coils can have on HVAC performance. Dust, debris and deposits on coil surfaces can interfere with heat transfer, restrict airflow and increase the demands placed on air-handling equipment.
Why coil cleanliness matters
Cooling coils transfer heat as air passes through the system. Contamination on those surfaces can reduce the effectiveness of heat exchange, potentially requiring equipment to work harder to reach the intended temperature. The effect on energy use depends on the extent of the build-up and the system design.
Debris can also obstruct airflow through a coil, affecting performance and potentially adding to the fan workload. Heavily contaminated equipment may need more intensive cleaning, while unnoticed deterioration can contribute to operational disruption.
Moisture and equipment hygiene
Cooling coils operate where moisture and airborne contaminants can collect. Persistent dampness can encourage microbial growth on surfaces, creating a further maintenance concern within the air-handling system.
Gibbons places coil cleanliness within a wider approach that also includes condensate management, suitable filtration and ventilation. Its article does not present coil treatment as a substitute for maintaining those other parts of an HVAC installation.
UVC as an additional maintenance option
The company’s UVC Division provides ultraviolet technology for HVAC applications. Correctly selected and installed systems can expose suitable coil surfaces to germicidal ultraviolet radiation, helping to control susceptible microorganisms on the treated areas.
Depending on the application and system design, this can help limit microbial build-up between routine maintenance visits. Gibbons describes UVC as a complementary measure within a planned maintenance strategy, alongside inspection and conventional cleaning.
Facilities managers and building operators can discuss their existing HVAC equipment with Gibbons to assess whether an appropriate UVC arrangement could support coil cleanliness and consistent performance.
