Air Duct Cleaning questions, answered by experts

If you don’t clean an evaporator coil, you’ll likely experience many unpleasant results, including higher energy bills, mold and mildew buildup, ice or frost buildup, a clogged condensate drain, and more. In addition, you’ll be dealing with an overall uncomfortable home and frequent HVAC breakdowns, plus your HVAC will continue to perform inefficiently.

There are a few ways to determine if a vent is open or closed. You can inspect the vent and examine the position of the fins. If there are spaces between them, the vent is open. If the fins are flat and touching, the vent is closed. You can also stand under the vent when the system is running to see if you feel air flowing through it.

Finding mold in an HVAC system is never fun, but the good news is you can clean it and send those spores packing. That being said, hiring a helping hand may be necessary to fully remove the mold and prevent regrowth. Professionals use specialized tools and cleaners, such as antimicrobial solutions and HEPA vacuums, to safely remove mold from ducts, coils, and other components. For small amounts of mold, homeowners can clean visible areas using a mix of water and detergent, but they must wear protective gear and avoid spreading spores.

According to the U.S. Environmental Protection Agency (EPA), duct cleaning hasn’t been proven to prevent health problems or to decrease dust in homes. However, if the ducts are filthy after a pest problem or major renovation, cleaning the ductwork may help improve the air quality in your home.

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.
