Duct Cleaning Questions We are  Often Asked

What types of things are found inside ductwork?
Some contaminants typically found in air ducts are mold, bacteria, dead human skin cells, dust mites, pollen, pet dander, insects, rodents and their droppings, sheetrock, wood and concrete dust, sawdust and even coffee cups and soda cans. This duct cleaning question is asked most often.

Will cleaning the air ducts help with allergy and asthma relief?
Yes, by removing the allergens from the ductwork. Every time your heat or air conditioning system turns on, it further aggravates allergies and asthma by forcing those allergens into the living space of the home and into the air you breathe. Actually, many customers tell us that their doctors are recommending air duct cleaning for that exact reason.

How can cleaning the air ducts actually save me money?
Cleaning the air ducts can save you money by increasing the efficiency of your heating and air conditioning system. A cleaner system does not have to work as hard to keep your home at a comfortable temperature. Research done by the EPA shows that a buildup of even .042 inches of dirt can result in a decrease of furnace efficiency up to 21%. The dust that stays in your system will accumulate on the fan blades of the blower motor, the coil and the inside of your ductwork, which can reduce air flow up to 40%. This translates into higher energy costs for you.

How does cleaning the air ducts help me with my housework?
Dust on furniture, the top of range hoods and ceiling fans will be reduced! Dust is made up of dirt, pollen, fibers, mold spores, hair and other allergy causing particles. About 95% of these are so microscopic, they will pass through your furnace filter and back into your home. Cleaning the ductwork means removing these contaminants from your home.

Why should I have my air ducts cleaned?
A building’s air duct network acts as its respiratory system. Dirt, dust, debris and microbial growth that build up inside of ducts “congest” the system and make it difficult for the building to “breathe” properly and function efficiently. Dirty air ducts are an ideal breeding ground for mold spores, bacteria (including Legionella), dust mites and other microbial growth. Dirty ducts can result in higher utility bills, reduced air supply and premature failure of expensive HVAC components.

Do you remove the vent covers?
Our technicians will remove the vent covers as long as doing so will not cause damage to the covers or the walls. Some homeowners’ have their vents heavily painted or wallpapered over or they have silicone sealed around the edges. We will not do anything that will cause damage in your home.

Do dust and dirt go throughout the house while you are cleaning?
No dirt will blow throughout the home during the duct cleaning. The power vacuum trucks we use are so strong, that any dust or dirt we are removing from the ducts will be pulled out directly to our truck. There is a constant negative pressure (vacuum) maintained throughout the entire cleaning process.

Are you licensed or certified?
We are licensed by the State of New Jersey as a Licensed Home Improvement Contractor. We are certified by the National Air Duct Cleaning Association (NADCA) and have been for many years. Our cleaning method strictly follows all NADCA specifications and guidelines.

Are you insured?
We are fully insured carrying both Liability and Workers Compensation policies in the amount of at least $1,000,000.

What happens to the holes you cut and drilled in my ductwork?
The access panel for the vacuum hose will be sealed with a specially made sheet metal patch which will be attached to the ducts with sheet metal screws. There will be a bead of silicone sealant run around the patch to ensure no air loss. The high pressure dislodger access holes will be plugged with a rigid plastic cap, specifically manufactured for such use. They will be airtight. 

What is the sanitizer and is it safe?
The sanitizers are totally safe, we use them in hospitals, schools and nursing homes. We currently utilize two different products for sanitization. Envirocon and Oxine. Both are chlorine based products manufactured specifically for ventilation system usage. They are EPA registered products and will kill mold, dust mites and many types of bacteria. They leave no lasting residue and break down to simple table salt. Envirocon is indicated for use in homes where people are present. Oxine usage recommends that the customer leave the home for 1 hour after it is applied. Click here for more information regarding the products we use.

Is the work guaranteed?
We stand behind our work unconditionally. We have been in business for over 48 years and have many satisfied customers!

How long does the cleaning take?
An average size home with one heating system takes approximately 1.5 -2 hrs to clean. The time varies according to how many air handlers are in the home, and the location of the air handlers, ie. crawl spaces, attics, etc. 

How often should I get my air ducts cleaned?
The National Air Duct Cleaning Association recommends that homes be cleaned every 3-5 years unless you have experienced a problem, such as a fire, flood, mold or had construction done in the home. Also allergy and asthma sufferers should clean their air ducts more often. 

How long have you been cleaning ducts?
We have been a family owned and operated business for over 45 years!

Do you use brushes to clean the ductwork?
No, we do not use brushes. Brushes are round and most ductwork is rectangle shaped, so the brushes cannot reach both sides of the inside of the ductwork. Brushes cannot bend around or reach into corners, so as soon as they hit a turn in the ductwork, they go no further. Also brush systems are powered by very weak systems and the vacuum cannot possibly remove all dust, dirt and debris inside your ductwork.  We utilize a high pressure compressed air and power vacuum truck system. The power vacuum truck is capable of moving 15, 855 cubic feet of air per minute. The high pressure compressed air-patented Viper Whip system has 220lbs of pressure and 200 cubic feet of air per minute. Our system can easily remove the most stubborn stuck-on debris inside the ductwork, especially in the corners. 

What is sick building syndrome?
Sick building syndrome and Building related illness are terms used to describe the negative health effects and illnesses directly related to the time spent in a building. Lawsuits directed at building owners have become more frequent as people realize that there is a relationship between poor indoor air quality and the illnesses it may cause. In the workplace and school, increasing health problems will result in decreasing productivity and attendance. Studies have shown that pollutant levels indoors are often 2-5 times higher than those found outdoors.
