Antimicrobial Advancements in HVAC: ADP’s Integration of Microban Technology for Enhanced IAQ

ADP & Microban’s Pioneering Approach for Optimal Indoor Air Quality


The HVAC industry is continually evolving, with a primary focus on enhancing indoor air quality (IAQ) and ensuring user safety. Advanced Distributor Products (ADP) in collaboration with Microban® stands at the forefront of this evolution. Their partnership aims to integrate antimicrobial technology into HVAC systems, addressing significant concerns regarding mold and mildew growth on HVAC drain pans, which can impact both the system’s longevity and the health of its users.

Understanding Antimicrobials

Antimicrobials are agents that kill or inhibit the growth of microorganisms. These agents are not just limited to pharmaceutical drugs but are also integrated into various products to provide an additional layer of protection against microbial growth, including bacteria, fungi, and viruses.

How Microban® Technology Works in HVAC Systems

Microban® has been a trailblazer in the realm of antimicrobial solutions. When incorporated into HVAC systems, it operates on a cellular level, disrupting and eventually terminating the growth of harmful microorganisms. This intrinsic feature, once integrated, does not wash off or diminish over time.

The Critical Role of HVAC Drain Pans and The Dangers of Mold Growth

The HVAC drain pans, often overlooked, play a pivotal role in the system’s functionality. They collect the condensation from the HVAC unit, ensuring smooth operation. However, their damp environment is a perfect breeding ground for mold and mildew. Over time, unchecked mold growth can:

  • Affect System Efficiency: Mold accumulation can restrict airflow, making the HVAC unit work harder. This not only affects the system’s lifespan but also increases energy bills.
  • Degradation of Air Quality: Mold spores can become airborne. When the HVAC system circulates air, these spores can be spread throughout a building, potentially causing respiratory issues, allergies, and other health concerns.
  • Corrode the HVAC Components: Mold and its byproducts can corrode the parts of the HVAC system, leading to potential breakdowns and costly repairs

ADP and Microban®: A Winning Partnership

ADP’s exclusive North American license to incorporate Microban technology in HVAC drain pans demonstrates a leap towards mold and mildew prevention. Given that ADP is now a leading producer of residential evaporator coils in the USA, this partnership not only assures quality but also promises enhanced longevity and safety for HVAC systems.

Benefits of Antimicrobial HVAC Drain Pans

Enhanced Air Quality

  • Mold Minimization: With the integration of antimicrobial technologies, the growth of mold, which is prevalent in damp conditions such as those of HVAC drain pans, is curtailed. Fewer mold colonies mean fewer spores are released into the air.
  • Reduced Health Concerns: Mold spores, when inhaled, can aggravate respiratory conditions and trigger allergies. By minimizing these spores, we are fostering an environment that’s more conducive to health and well-being.
  • Freshness in Circulation: Apart from harmful mold spores, bacteria and other pathogens can also be inhibited, ensuring that the air circulated remains pure and fresh.

Extended HVAC Lifespan

  • Less Corrosion and Wear: Mold and its byproducts can have a corrosive effect on the metal components of an HVAC system. By halting its growth, the rate of corrosion decreases, leading to increased durability.
  • Consistent Efficiency: Mold build-up can obstruct critical components and pathways, impeding the system’s operations. Antimicrobial drain pans ensure that the HVAC systems maintain their operational efficiency over time.
  • Preservation of System Components: By mitigating mold growth, the internal components of the HVAC system, especially the evaporator coils, remain untarnished and functional for longer periods.

Energy Savings:

  • Optimal Airflow: Mold accumulations can obstruct air pathways, forcing the system to expend more energy to achieve the desired temperature. An antimicrobial drain pan ensures that such obstructions are minimal.
  • Thermal Efficiency: Mold growth, especially around coils, can affect the system’s thermal transfer efficiency. By ensuring the coils and adjacent areas remain clean, the HVAC system can operate with better energy efficiency.
  • Lowered Energy Bills: An efficiently operating HVAC system, devoid of mold blockages, consumes less power. This directly translates to savings on monthly energy bills.

Reduced Maintenance Costs:

  • Fewer Cleanups: With mold growth in check, the frequency of required maintenance cleanups is reduced, leading to direct savings in terms of time and resources.
  • Extended Maintenance Intervals: An antimicrobial HVAC drain pan prolongs the periods between routine maintenance, which means fewer interruptions and service calls.
  • Cost Savings on Repairs: Mold can cause component malfunctions and breakdowns. By mitigating its growth, the number of repairs required over the system’s lifetime diminishes, resulting in substantial savings.

Case Study

In a recent study involving homes equipped with ADP’s antimicrobial HVAC drain pans, there was a notable 60% reduction in mold-related complaints and subsequent maintenance requests, showcasing the effectiveness of this technology.

Why is Antimicrobial Integration Essential for HVAC Systems?

Simply put, an HVAC system is not just about heating and cooling; it’s about providing safe, clean air. Mold is ubiquitous; its spores are part of our environment. But in confined spaces, with circulating air, it becomes a health hazard. Integrating antimicrobial technology like Microban® ensures that the air circulated is not just comfortable but safe.


As we move towards an era where indoor air quality is as vital as comfort, the alliance of ADP and Microban® is a step in the right direction. Their commitment to innovation and safety ensures that HVAC systems of the future will be more efficient, durable, and most importantly, healthier.
