If your HVAC system is dirty, it can pose a threat to your health by reducing the air quality. To make sure your heating and cooling systems are working efficiently and not costing you unnecessary money, you may need to make time for an air duct cleaning. 

Before deciding you need an air duct cleaning, here are a few things you should look for:

• Dust Buildup: Open one of the vent covers in your home. If you see a lot of dust residue, schedule an air duct cleaning. Typically, home systems benefit from cleanings every three to five years, but any extra remodeling or other work that may release excessive amounts of dust into your home could call for an extra air duct cleaning. 
• Visible Mold: On occasion, moisture causes mold problems in air ducts. You may be able to see the mold in the ducts or near the inside of the vents, which indicates you should schedule an air duct cleaning. Mold can lead to serious health problems, especially when it is circulating throughout your HVAC system into your home, so make sure you act right away if you notice mold in your ducts.
• Rodent or Insect Signs: Inspect your air ducts every month or two. When you do, keep an eye out for signs of insects or rodents. You may spot dead insects, scratch marks, or animal droppings—all indications that you have an insect or rodent infestation. If this is the case, seek an air duct cleaning to eradicate the animals or bugs and ensure the air in your home is healthy for you to breathe.
