Abstract: Currently, there are no products available which allow a user to treat microbial and bacterial growth inside a HVAC condensate drain pan without first, gaining access to the drain pan by removal of the front cover of the HVAC unit. Our HVAC Enviro-Clean Condensate Drain Pan and Coil Cleaning System will accommodate the introduction of non-corrosive algaecides and/or biocides and cleaner fluids via an internal reservoir and plastic hosing system that can be easily used and maintained by the consumer. A reduction of microbial and bacterial growth will have a positive impact of Indoor Air Quality.
