Air Ducts are like the lungs of your home. The air duct system circulates and delivers the heat or cool to the many rooms of your home. The air duct system then returns that same amount of air back to your heating and air conditioning system. And just like everything else in your home, your air ducts will get dirty. Trying to DIY your air duct cleaning system could be a more difficult task than you think. This is because the ductwork is hidden behind layers of flooring, sheetrock, or in your attic. For this reason, it is important to consider professional air duct cleaning. Here are four signs that can help determine if your air ducts need cleaning.


There is something satisfying in having a clean home, but if you notice a rapid collection of dust after cleaning, it could indicate a dirty air duct system. Some noticeable things to look for include a collection of dust after cleaning, the outside of grills/vents have a lot of dirt/grime build-up, and the tops of ceiling fans have a lot of dust collection. Professional air duct cleaning can determine if any blockages exist and reduce dust build-up and dust circulation in your home. 


Dust can be composed of irritants such as pollen, microscopic organisms, plant material, and pet dander. According to the National Air Duct Cleaners Association, NADCA, a typical home, approximately six rooms, can have up to 40 pounds of dust created in a single year. The amount of dust can increase due to pets, smoke from cigarettes/cigars, and home renovations/remodeling projects. 

The irritants circulating as dust material could cause unexplained respiratory issues such as allergies, sinus, or asthma. If this is a concern, a certified technician can determine what best fits your needs. Recommendations can include adding indoor air cleaners, fresh air systems, A/C Filtration, dehumidifiers, UV lights, or air duct sealing, Aeroseal. These additions can further combat dust sources. 


Your energy bills, when concerning your heating & cooling costs, should be predictable each year. If you notice that your energy bill is higher, a good tip to consider is getting an inspection for your HVAC system and air duct system. Mechanical problems with your HVAC system or clogs/leaks in your air ducts could reduce the efficiency of your heating and cooling system. These issues can lead to a rise in energy usage. Having a trained HVAC technician inspect your unit and the air ducts can determine if repairs are needed or if your air ducts need to be cleaned & sealed. Addressing this could reduce your energy expense and save you money.


If you notice rooms in your home have less airflow, this could indicate a clogged air duct system. Dirt, dust, and other debris in your air ducts can restrict the airflow and cause inconsistent heating and cooling. Damaged or dented air ducts could also be the cause of uneven airflow. Consulting a trusted and certified HVAC technician for an inspection can help address these concerns.
