A dirty furnace can circulate dust, allergens, and pollutants throughout your home, negatively impacting indoor air quality. This can cause respiratory issues, allergies, and overall discomfort for occupants. Dust and debris in the furnace can harbor mold, bacteria, and other contaminants, distributed through the ductwork and into the living spaces. Regular cleaning helps maintain a healthier indoor environment by removing these contaminants and ensuring the furnace operates efficiently, providing clean, filtered air throughout your home.
