Why Is Duct Sealing Part of Heating Service?

When people think of professional heating service, they probably think of checking the pilot light, or the heat exchanger, or any one of a dozen other internal components. What they probably don’t think of is the ducts. Ducts are often neglected, due to their unobtrusive natures, but they need maintenance just as much as any heating system. Part of that maintenance is duct sealing. Let’s take a look at why duct sealing is so important.

Airborne Contaminants

Though most people do not know it, the air quality in their homes can be drastically affected by microscopic airborne pollutants and contaminants. Things like viruses, bacteria, insect dander, dust pollen, and mold are commonly found in a home’s air, each of which is capable of negatively affecting a person’s health. These are linked to ducts because they are circulated through them whenever a forced air system is turned on.

The ducts themselves provide an ideal habitat for these pollutants, as they are usually undisturbed by human activity. In the darkness and stillness of the ducts, microorganisms can reproduce freely and a sizeable amount of dust and pollen can build up. This is why duct cleaning and sealing is so important.

Duct Cleaning and Sealing

The first step to improving environment in the ducts is to clean them. If the ducts are a typical sheet metal variety, they can have dust and debris sucked out of them by a powerful vacuum that HVAC technicians use. If the ducts are of the more rare tube or cloth type, the technician will have to carefully clean them using a special set of brushes. After the ducts have been thoroughly cleaned, it is time to seal them.

Duct sealing involves the closing of any leaks in the ducts, both to prevent air from escaping and things like moisture from coming in. After the duct integrity has been restored, it is treated with a chemical mixture designed to kill off any microorganisms that may be lurking on the surface. That way, you don’t have to worry about exposing yourself to germs every time you turn on your heater or air conditioner.
