Regular cleaning, sealing ductwork, and ensuring proper airflow paths keep systems functioning optimally, maintaining energy efficiency.

Whether air duct cleaning is worth the cost depends on your specific situation. While it hasn't been proven to prevent health issues, it can be beneficial for improving indoor air quality by reducing contaminants, which is especially important for households with members who have asthma or allergies. Cleaning is generally considered worthwhile if you notice visible mold growth, signs of a pest infestation, excess dust, or debris blowing from the vents. It is also recommended after a major home renovation. Additionally, if your ducts are dirty enough to leak air, cleaning and sealing them can improve your HVAC system's efficiency, ensuring the heated or cooled air reaches your living spaces and potentially leading to long-term savings.

Spring and fall are the best times to hire a pro to clean ductwork. It’s a good idea to clean and maintain your ducts before the HVAC system will be busy regulating temperatures day and night. Scheduling a cleaning in the spring and fall ensures that the system will be at peak efficiency during the summer and winter.

Clean return air vents by using a microfiber cloth soaked in warm, soapy water (or a mild cleaning solution, like vinegar and water). Wipe the interior of the vents, paying close attention to the corners and crevices where dust likes to hide. Use a vacuum brush attachment or handheld model instead of a cloth if desired. Additionally, once or twice a year, remove your air vents and soak them in warm soapy water for 30 minutes before cleaning, drying, and putting them back on.
