We completed an air duct cleaning at a large home in Davenport, which included servicing an additional air handler unit. The ductwork, air handler, and blower fan all showed significant dust accumulation, and several supply boots displayed suspected microbial growth. To address this, we sealed the affected boots with mastic to help prevent future growth and maintain system integrity. Our vacuum truck removed the majority of debris throughout the system, and we followed up with a sanitizing fogging treatment after cleaning. To protect the home during service, we sealed off vents to keep dust contained. The before‑and‑after photos clearly show the improvement—cleaner duct surfaces, healthier airflow, and better overall system performance. For long‑term results, we recommend professional air duct cleaning every three years. Routine maintenance helps reduce dust, improve airflow, and support a healthier, more efficient living environment
