Location is at the beginning of future dust and mold infestation, imbalance in the ductwork is creating the perfect environment for dust to breed and mold to attach to it, causing the debris we see on the grilles. This would be considered a 3.5/10. To reduce the issue we recommend a duct sanitation which is a non-evasive mist to target and kill mold spores and dust mites. Installing the Reme-Halo's will help with future sanitation of the system. Replacing the Supply Grilles is removing it at the end point. These steps will not remedy the situation but will improve the air quality and slow the progression. Return grilles will not be replaced due to highest contamination being in the supply part of the system.
