HVAC Air Duct Cleaning
Spring is springing here in Northeast Alabama. With that comes thoughts of spring cleaning, and for some of us, indoor air quality. It seems that everything in the area has a nice yellowish tint of pollen. That, paired with the fact that I passed three air duct cleaning company vans on the way in to work, got me thinking it would be time to share the benefits of having your air duct system(s) cleaned.
A common rule of thumb used by NADCA(National Air Duct Cleaning Association) is "If your ducts LOOK dirty then they probaby ARE dirty". This seems elementary but it is usually true.
The first reason is indoor air quality. It is calculated that up to 40lbs of dust is created annually in a normal home just through everyday living. An HVAC system works like the lungs of a home and that dust we mentioned is recirculated 5 to 7 times per day building up in the duct system. This leads to potentially poorer air quality and a need for higher frequency of dusting/cleaning.
The second reason to clean air ducts is energy savings.With 25 to 40% of the energy used to heat and cool homes wasted annually dust and contaminants in the HVAC system cause increased strain on the unit and shortens the life. With a clean HVAC system the opposite is true resulting in less contaminates and longer system life.
