About
Air ducts play a vital role in distributing heating and cooling throughout Washington, D.C. homes, but they don’t last forever. On average, ducts should be inspected every few years and replaced every 15–20 years, depending on condition. Signs it’s time for replacement include visible damage, excessive dust buildup, mold growth, or inconsistent airflow between rooms. In older D.C. rowhouses and apartments, ducts may have leaks or outdated materials that reduce HVAC efficiency. Replacing ducts improves airflow, lowers utility bills, and enhances indoor air quality by preventing pollutants from circulating. New ductwork also supports modern HVAC systems, which require tight seals to operate efficiently. For D.C. homeowners, scheduling a professional duct inspection provides peace of mind and ensures that heating and cooling systems operate at peak performance. Replacing old ducts is an investment in comfort, health, and long-term energy savings, making it an important step in maintaining an efficient home.
