So, what is the point of duct cleaning, anyway? Do dirty ducts actually make that much of a difference? Actually, yes. Allowing dirt and dust to build up in your ducts is actually very bad for both their operation and your health. First, too much dust and dirt buildup in your ducts can act as an insulating agent, restricting the flow of air through them and lessening the output of your heater and air conditioner. This can cost you quite a bit of money in the long run, as your systems have to work harder to achieve the same temperature changes.
Second, dirt and dust are not the only things you need to worry about building up in your ducts. There are millions of microscopic contaminants floating around in your home’s air, including pollen, dust mites, dander, germs, and mold spores. When they’re relatively dispersed, your body can usually repel them without feeling any ill effects. However, they have a tendency to build up in your ducts over time. Every time you turn on a forced air system, a large dose of these contaminants is circulated around the house. That makes it much more likely that you’ll have an allergy attack or get sick.
Duct cleaning removes all of these harmful materials from your ductwork, keeping your forced air systems energy efficient and allowing you to breathe easier.
