Frequently Asked Questions
How do your air ducts get dirty?
It’s natural for dust and other contaminants to build up in our homes and businesses over time. The difference is that you cannot clean out your air ducts using a vacuum or duster, unlike the rest of your house. Dust, dirt, allergens, and mold can all accumulate inside your HVAC system over time. If you have pets, hair and dander are also likely to build up inside your vents. As your HVAC system releases air into your home, it will circulate these contaminants into your household air. The contaminants will also make your system run less efficiently. They clog up your system’s filters and can obstruct the vents. For these reasons, the National Air Duct Cleaners Association recommends that homeowners clean their air ducts every 3-5 years. If the air duct vents in your property are visibly dirty or if you can see accumulated contaminants, it’s probably time for a professional cleaning from a professional duct cleaning company.
What are the benefits of cleaning my HVAC air ducts?
Having clean air vents means that you won’t have contaminants circulating throughout your house. This helps to make your entire home cleaner and healthier. Perhaps the most important thing is that it improves your home’s air quality. Accumulated contaminants, particularly if they include allergens or mold, are very bad for your respiratory health. They can lead to sinus problems and respiratory infections. If you feel like you are getting sick more than usual, particularly when you spend more time at home, dirty air ducts may be at fault. An unclean HVAC duct system can be particularly problematic for people with asthma and allergies. Dust, pollen, mold, and allergens can make asthma and allergy symptoms significantly worse. Cleaning out your ducts can help you to stay healthy at home. Professional, True Ducts air duct cleaning will also help your HVAC system to run more efficiently, saving you money. We know how much you depend on your HVAC system in the cold Maryland winters and hot summers. A clean air duct system that works efficiently will result in long-term energy savings for your home.
My duct-work is the flexible type. Will your service damage my ducts?
No. Most ductwork in newer construction in Maryland is like yours, and that is why we use the method of air duct cleaning that we do. The negative air method that we use cannot damage your ductwork. We are simply vacuuming the ducts to remove loose dust and debris under controlled pressure verified by a suction gauge on the negative air machine. Any contaminants that remain in the ducts are neutralized when we sanitize the system to kill microbiological growth and to prevent their regrowth.
Will we need to leave the house while you clean our ducts?
No. All of the air coming out of our machines is triple filtered. The HEPA filter ensures that nothing harmful comes out into your home. (The air you are breathing before we clean your ducts is the risk to your health.) The natural disinfectant that we use to sanitize your ducts is also harmless to humans and pets alike, and requires no personal protective equipment, and no first aid if ingested, inhaled, or contacts skin or even gets in your eyes, and yet it kills 99.9 % of germs, and it continues to inhibit their regrowth for up to 18 months.
Do you need to hook your machine up to every duct in the house?
No, just one. Our machine enables a reverse flow of air from all vents that normally blow out. We block your return vents at the filter/s or the air handler, turn your system off, and start our machine. This makes it safe for us to “dust” off contaminants on the remaining vents throughout the house with a pole duster. We clean the return vents with a second HEPA filtered back-pack commercial grade vacuum cleaner.
Is the black stuff coming out of my vents mold?
It is evidence of mold contamination, as well as other microbiological contamination including mildew, bacteria and viruses. Dead mold spores turn black and show themselves on the grills, the ceiling, and any close fan blade tops. This material has a greasy feel, differentiating itself from dust which usually is light and “fluffy”, and is white or light gray in color. To prove the existence of mold, you need a live sample from inside your system. Even small amounts of mold can be dangerous to your family’s health.
Can duct contamination really make me sick?
Yes. It is our experience that when we see the black discharge on every vent grill in a house, some one in the family is ill. After we sanitize these homes, we receive feedback, all positive, including but not limited to the following:
My asthma symptoms are gone
My allergies are gone
I am sleeping much better
I don’t wake up with headaches anymore
I no longer wake up with a stuffy nose or a scratchy throat
My nose-bleeds have stopped
My dog’s skin rash has cleared up
