It used to be nobody did it, now homes are built much tighter to save on energy. Houses don’t breathe like they used to.
In the old days, houses naturally had more of a draft, but now the push is to build homes tight to help save on energy.
Energy is expensive and houses are built like an envelope now, so what happens is everything that comes into your house gets trapped in your house.
This includes external or environmental elements as well as human skin dander, dead skins cells, pet dander and dust.
All of that has no place to go and it ends up collecting, a lot of stuff gets trapped and your furnace system ends up re-circulating it.
According to the U.S. Department of Energy, 25 to 40 percent of energy used for heating and cooling is wasted because contaminants cause furnaces or air conditioning units to work harder and shorten the life of your system.
When ducts get dirty, they start narrowing the opening and therefore it’s harder for air to move through properly and doesn’t flow through as smoothly and it should.
On average duct cleaning takes about two to three hours and costs about $300 but really depends on the size of the house and your setup.
There are a variety of different kinds of equipment that is used to clean ducts including portable machines and units that are connected to trucks which is much more effective.
Aside from dust and other environmental contaminants, cleaning contractors have found a variety of items stuck in vents when it comes time to clean them out.
Kids like to throw toys down the vents, it’s amazing what is found sometimes… stuffed animals and all kinds of toys. Kids will hide stuff in vents so you can imagine what contractors might find. It seems like a good hiding spot but then they forget about them.
Contractors also find other not so fun items like dead mice in duct spaces and that can really affect the output of a furnace, adding that the average home collects up to 40 pounds of dust alone each year.
By keeping the ducts cleaned on a regular basis, families are guaranteed a much better living environment
