Air Duct Cleaning questions, answered by experts

Yes, it is essential to seal all duct leaks. Even small leaks in your ductwork can lead to energy waste, reduced efficiency, and decreased comfort in your home. Sealing all leaks, whether minor or significant, ensures that your HVAC system operates at its best, delivering conditioned air where needed without losses. This comprehensive approach to duct sealing is crucial for maximizing energy efficiency and maintaining a comfortable indoor environment.

Water accumulation can occur due to either leaks or condensation on or near cooling coils. It's crucial to inspect for leaks, perform necessary repairs, and ensure regular maintenance checks for your coils and drain pans. Be sure to empty the drain pans completely, as any standing water in the pan indicates that it is not functioning as intended.

The Centers for Disease Control and Prevention (CDC) recommends using an EPA-registered disinfectant product to disinfect a house properly. If such a product isn't handy, a strong bleach solution can disinfect high-touch surfaces. Before hiring a professional, be sure to discuss the type of chemicals and disinfectants they plan to use to ensure they’re safe for household use.

The primary drawback to cleaning air ducts is that you could damage the HVAC system or the ductwork. If you damage a seam or knock a section loose, you could allow heated or cooled air to escape, which costs you money through reduced system efficiency. It can also be a time-consuming process to clean air ducts if you have a large home or complicated ductwork layout.

Air vents should never be blocked. It can disrupt the airflow in your home and make rooms too stuffy, hot, or cold. If the vents are blowing out cold air when you want hot air, covering the return vents won't solve the problem. You either have a dirty air filter, furnace problems, or, more than likely, leaky air ducts that need sealing.
