$129 Duct Fogging!

Air Quality Improvement: The fogging solution helps eliminate mold, mildew, bacteria, and other contaminants that can accumulate inside the ducts over time. This helps to improve the quality of the air that circulates through the HVAC system and, ultimately, the indoor air quality of the building.

Odor Elimination: Duct fogging can be used to neutralize unpleasant odors caused by mold, mildew, pet dander, cooking, or other sources that may be trapped within the ductwork.

Disinfection and Sanitization: By using appropriate disinfectants or antimicrobial agents, duct fogging can help reduce the spread of germs and bacteria within the HVAC system, contributing to a healthier environment.
