Add moisture from condensation, and the cooling coil can become an environment where dirt and biological contamination gradually accumulate.The result?A coil that was designed to efficiently transfe...

While these systems are essential for maintaining comfortable indoor conditions, their internal cleanliness and ongoing maintenance can also influence the overall indoor environment.One technology increasingly being considered as ...

In a home that is poorly ventilated, damp, cold or inadequately maintained, these contaminants can build up.And in New Zealand, indoor air quality can be particularly important.Our homes need to balance warmth, insulation, ventilation and moisture c...
