Duct Cleaning


Q. Should I have my ducts cleaned?

A. Probably not.  At least not before you have determined how they became dirty to begin with.

The question that needs answering before having your ducts cleaned, is how did they get dirty or moldy in the first place?  Dirt and dust inside duct systems wouldn’t be there if the dirt and dust hadn’t first made it past a filter, a wet evaporator coil, and a blower wheel.  Before cleaning a duct system it would be a good idea to clean the evaporator coil and blower wheel and install a good air filtration system.  A good air filtration system would have prevented any dirt and dust from ever reaching the duct system.

If the ducts need cleaned to remove molds or other microbial growth, without correcting the problem that caused the mold, it will be back in a very short period of time.  Most microbial growth in duct systems is the result of poor duct design.  The most likely problem is moisture in the duct system due to duct leaks, poor duct insulation, high static pressures, reduced air flow or bad duct design.  Cleaning the duct won’t fix the problem.
