The answer to 'when to service air duct sealing' is that you should have your air ducts inspected and sealed every 3-5 years, or if you notice any signs of air leaks or inefficient heating/cooling. Proper air duct sealing is important to maintain energy efficiency, indoor air quality, and the overall performance of your HVAC system.
During a duct sealing service, an HVAC technician will thoroughly inspect your ductwork for any cracks, gaps, or other areas where air may be escaping. They will then use specialized sealants and tapes to close up these leaks, ensuring your ducts are airtight. This helps reduce energy waste, improve airflow, and prevent dust, pollen, and other pollutants from entering your home through the ductwork.
