Duct Cleaning and Sanitizing Service

Shield Comfort Heating & Cooling offers the most affordable, and complete duct cleaning available in our service areas. For a lower price than our competition, you can rest, and breathe easy knowing your ductwork has been professionally cleaned and sanitized.

What separates Shield Comfort Heating & Cooling from other contractors? Aside from price, nothing! We will do a thorough job removing dust and contaminants from the duct system in your home.


We utilize a different type of machine using positive pressure to rid your ductwork of all the undesirable debris. The system we utilize doesn’t require large holes of 12- 13 inches in diameter to be cut into your air duct therefore there are no wasted man-hours cutting and creating patches to cover these new holes.

Our sanitizing system is superior to the competition as well! Foggers used by other contractors generate a mist (fog) from a chemical which is then blown into your duct system through the blower cabinet or the return system. Fogging systems do a really good job blowing these chemicals into, and throughout your home, for you to breathe. But they aren’t the most effective means of keeping the chemical in the duct system where it will perform its intended purpose. Studies have shown that most of the chemical used in fogging systems is simply blown out into the living space and little remains behind in the duct.

The sanitizing system we utilize uses air pressure with whips and atomizers. This means no fog! We sanitize each vent individually without using your system’s blower to distribute the sanitizer throughout your duct. This method is superior to fogging because nearly 100 percent of the sanitizing agent is left behind in the ductwork where it can remain for months doing its job and preventing biologic growth and odors.

Why Should I Clean My Ductwork?

According to the EPA, levels of pollutants may be 2-5 times, and occasionally 100 times greater inside than outdoors. With this knowledge, indoor air pollution is quickly rising to the top of a list of concerns for homeowners. Knowing that the air in your home is worse to breathe than the air outside, it’s no wonder homeowners can do to improve the quality of the air they’re breathing.

Up to 40 pounds of dust is created annually just through every day living in an average-size home. That 40 pounds of dust can contain dust mites (a common source of allergens) chemicals, biological matter, shed skin cells, and dander. These contaminants are taken in by your heating and cooling system and then recirculated through your home several times a day. Imagine what that buildup looks like inside ductwork.

Contaminated ducts can contribute to greater health issues or harboring contaminants that could cause serious problems for people with respiratory health conditions. NADCA and Angi both recommend having your air ducts cleaned once every 3-5 years, or on an as-needed basis. Making renovations to the home can decrease the amount of time between cleaning. Dust and debris stirred up during the construction process can quickly contaminate your home’s duct system. After any major renovation duct cleaning should be considered and performed. As much as we all love our furry friends, we all know what it’s like to chase around shed hairballs roaming the walkways and in corners. Often times this shed hair gets picked up by your heating and cooling system and distributed throughout the home. This accumulation of shed hair creates a perfect home for pests such as dust mites and other undesirables.
