The Efficiency of your Duct
If you are experiencing high utility bills, uncomfortable rooms or a hot or humid home, you may need an air duct inspection. Over the years, air ducts collect dust and other impurities, decreasing the air quality of your home and affecting the efficiency of your air conditioning system, making allergies, asthma and other illnesses worse.
It is also possible that your air ducts were initially improperly sized or poorly designed. Holes in leaking air ducts allow bugs from the attic to make their way into the rest of your house.
