Should You Have the Air Ducts in Your Home Cleaned?

Air Design Services, Inc. Uncategorized 1 Comment

We routinely get calls from customers asking us if we provide air duct cleaning services. In our industry cleaning duct work is discussed as an added profit center to the list of HVAC (Heating, Ventilation, & Air Conditioning) services provided to homeowners. We have never provided these services ourselves but have worked with Duct Cleaning companies in hospital “sterile” environments. For the average homeowner we do not feel that duct cleaning is necessary.
According to the EPA “duct cleaning has never been shown to actually prevent health problems. Neither do studies conclusively demonstrate that the particle (e.g. dust) levels in homes increase because of dirty air ducts”.
There are specific situations that can require air duct cleaning:

* Substantial visible mold growth

* Ducts infested with vermin

* Ducts clogged with excessive amounts of debris

In the case of mold it may be necessary to simply replace the duct to ensure the mold does not return. It is also essential to determine the cause of any of these situations to avoid a re-occurrence. The EPA does recommend “that if you have a fuel burning furnace, stove or fireplace, they be inspected for proper functioning and serviced before each heating season to protect against carbon monoxide poisoning. Cleaning dirty coils, fans and heat exchangers can improve the efficiency of heating and cooling systems. However, little evidence exists to indicate that simply cleaning the duct system will increase your systems efficiency”. We recommend installing a high efficiency air cleaner on your system for continual cleaning (with a one time cost) rather than duct cleaning over and over again.

If you find you do have a situation that requires duct cleaning, the EPA has a list of suggestions for choosing a provider at the following web address.

  1. I had no idea that you should have a yearly cleaning of the air ducts if you use a fuel burning furnace. I can see why this would be a good idea to do in order to avoid any accidental fires. Should I ever move into a house with this type of furnace, I’ll have to remember to keep this in mind.
