What about duct cleaning?

Eddie Hutton, Partner, answers the question this way.

You might ask if service firms can really clean ducts.  Well, because air conditioning ducts twist and turn their way through your house and because ducts have screws and edges that collect dust, duct cleaning is only 50-60% effective in removing dust and dirt. If you want a clean duct system you have to take the whole duct system out, clean it,  and put it back in. It is virtually impossible to clean a duct system while it’s in place. Most duct cleaners are a spinning polyester brush that goes through the duct.  The brush gets some of the dirt but leaves 30% or so in place. You pay a lot of money but you still have dirt and rust spots that pick up more dirt over the next few years.  Sorry, but duct cleaning is an expensive way to not get much!   The US Environmental Protection Agency (EPA) says what I just said using bureaucratese.  EPA says “no evidence suggests that such cleaning would be detrimental, provided that it is done properly.” The EPA website with lots of information is here.

What about Radon Gas?

Eddie Hutton, Partner, answers the question this way.


 Everyone needs to think about radon gas. Radon is a radioactive, colorless, odorless, tasteless gas. Some say radon causes lung cancer.  Radon gas comes out of the ground and is produced by the decay of radioactive particles such as uranium found in the limestone that underlies Middle Tennessee. If you have radon gas you need to ventilate your crawl space or basement to remediate your exposure to the gas.  The photos show one way with black plastic covering the ground in the basement of a 1925 house. Outside a powered fan pulls air from under the plastic and expels it into the atmosphere.  You can tell if you have radon that exceeds safe limits by going to your local hardware store and picking up a radon gas detector kit.  The photo below shows an example of one type kit. More information here.
