If your home has dirty air ducts you could be harming the health of your family. Asthma, allergies and lung issues may be made worse from allergens that may be getting circulated throughout your home. Dirty air ducts can contribute to an increased level of respiratory infections or sinus infections. Pollutants being distributed by unclean ducts can also cause common colds. Those same pollutants may cause or worsen skin conditions like eczema. It is recommended that you have your ducts cleaned every 3-5 years by a professional Bartlesville Air Duct Cleaning or Tulsa air duct cleaning company.
