Because they get dirty! Over time dust, debris, and dirt can build up in your duct system. This build-up can cause poor airflow which will not only affect the system’s ability to heat and cool your home but will also cause your system to work harder and use more energy. Allergens and bacteria can also be housed in dirty ducts and be spread throughout the home.
Some occupants are more sensitive to air contaminants than others. If you have people in your home that suffer from asthma and allergies, as well as young children and elderly residents, then duct cleaning should be more important to you. Cleaning these contaminants out of the ducts will prevent them from being systematically spread throughout your home and affecting the more sensitive residents.
Duct cleaning is an essential service for all pet owners. Although we all love our furry four-legged friends like they are a member of the family they do leave hair everywhere, and they may not always smell the best. Pet hair and dander can be pulled into your system’s return ducts while it is cycling air throughout your home. This build-up will not only attract other airborne particles to collect in your ducts but will transfer the pet odors through the duct system to other parts of your home.
