Indoor Air Quality in Tupelo, MS

Usually biological growth on a wet evaporator coil, in a condensate pan that does not drain fully, or in duct insulation that has been exposed to moisture. Correcting drainage and cleaning the coil addresses the source rather than masking the odor.

Often not. A correctly sized system that runs long cycles removes a great deal of moisture on its own. Whole home dehumidification helps in houses with oversized equipment, in mild shoulder seasons when the system barely runs, and in homes with a damp crawl space.

No. A filter that is more restrictive than the system was designed for reduces airflow, which lowers capacity and can freeze a coil. The right approach is the highest efficiency your filter area and duct system can support, which sometimes means enlarging the filter rather than tightening it.
