Exterior wall mount HVAC units, especially in humid climates, can become hotspots for mold and bacteria due to moisture accumulation and limited air circulation. Incorporating UV-C technology in these units is a game-changer. It effectively targets and disrupts the DNA of mold and bacteria, preventing their growth. This is particularly beneficial for maintaining a cleaner and healthier air output from these units, enhancing indoor air quality where these HVAC systems are used. Remember, regular maintenance combined with UV-C treatment can significantly reduce the risk of microbial buildup in these units.

Biofilms, those sticky clusters of microorganisms, can also be a big issue for exterior wall mount HVAC units. In these units, biofilms tend to cling to internal components like coils and drain lines.

What this means for your exterior wall mount unit is trouble: reduced efficiency due to obstructed airflow, hindered heat exchange, and unpleasant odors and poor air quality inside the building. Plus, if left unchecked, these biofilms can be a launchpad for further microbial growth, affecting more than just the unit itself. It's essential to regularly check and treat these areas to maintain the health and efficiency of your HVAC system.

For exterior wall mount HVAC units like Bard units, regular cleaning is crucial but can be challenging. Traditional methods are labor-intensive and might not remove all biofilm, leading to quick recurrence. Using high-pressure washing for stubborn biofilm can be effective, but risks damaging the unit over time. Regular, gentle maintenance is key for these units.

For exterior wall mount HVAC units, frequent high-pressure washing can lead to costly premature failures. This method can damage the fins critical for heat transfer, reducing efficiency. UV-C technology is a cost-effective alternative, offering effective treatment without the risk of mechanical damage, thus saving on potential expensive repairs or replacements
