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.

While your forced heating system runs, it can pick up dirt, dust, hair, and other particles from inside your house. Changing your furnace filters regularly is key to preventing this debris from getting stuck in your ducts and swirling around your home. With some types of furnaces, there’s also the potential for carbon monoxide leaks. However, staying up-to-date with your HVAC inspections and installing carbon monoxide sensors can help mitigate this risk.

The frequency for cleaning air vents can vary. As a general guideline, you should inspect and clean your return air vents at least once a year, while a more thorough cleaning of all vents is recommended every two to five years. However, you should clean them more frequently if you notice a significant buildup of dust or debris on the vents, see mold growth, find signs of a pest infestation, or notice an unusual amount of dust accumulating on your furniture. More frequent cleaning may also be necessary to maintain good indoor air quality if household members have allergies.

Not cleaning your house on a regular basis can lead to elevated allergen levels, pest problems, mold growth, damaged belongings, and parts of your home falling into disrepair. Consistent cleaning prevents problems that can lead to illness and ensures you’re aware of the condition of everything in your home so you can maintain and repair things as needed.
