The national average dryer vent cleaning costs range from $190 to $260. Dryer vent or duct cleaning costs can vary based on where you live in the country and what ductwork repairs may be required. Duct cleaning pros will use a brush cleaning method, a forced air vacuum, or a combination of the two to remove lint and other debris that can collect in your dryer duct, lint trap housing and vent. If left unchecked, this buildup of highly flammable debris can catch fire and lead to a home fire, says the U.S. Consumer Product Safety Commission. In addition to home safety, a great reason for regular cleaning is the money you’ll likely save on energy bills and improved indoor air quality. Pros may offer a lower rate on their dryer duct cleaning costs when you also hire them to clean your entire HVAC duct system. To ensure you’re working with a pro who will keep your home as safe as possible, read their reviews and check whether they have been certified by a reputable organization such as the National Air Duct Cleaners Association (NADCA) or the Chimney Safety Institute of America (CSIA). Many duct cleaning pros will also show you before-and-after photos as proof of the cleaning.
I moved into a house built in 2003 last year, and spent a lot of time researching air filters because I realize air pollution inside the house is many times higher than outside, and my health and the health of children and youngers can be so adversely impacted by inhaling these indoor pollutants.  I spent a lot of money on the best filters because here in northern Kentucky, I discovered I am allergic to something in the air starting in Spring that made me sick for 10 days - sort of a Upper Respiratory Illness.  It never occurred to me the previous owner had never cleaned the air ducts, although he had both very young children, two dogs and a cat.

I recently did some remodeling and figured I’d get the air ducts cleaned in our 12 year old home. After obtaining 4 estimates between $572 and a whopping $3,075 for 25 vents and 2 air handlers, I knew I was in for a ride. I read through this blog and decided to use a $79 inspection camera I just found online (Home Depot) to take a look at all my ducts by removing the ceiling grilles first and then try to get into the ducts from the other end. From what I have just learned here, I believe that will take care of my “concerns”.


Most organizations concerned with duct cleaning, including EPA, NADCA, NAIMA and the Sheet Metal and Air Conditioning Contractors' National Association (SMACNA) do not currently recommend the routine use of sealants to encapsulate contaminants in any type of duct. Instances when the use of sealants to encapsulate the duct surfaces may be appropriate include the repair of damaged fiber glass insulation or when combating fire damage within ducts. Sealants should never be used on wet duct liner, to cover actively growing mold, or to cover debris in the ducts, and should only be applied after cleaning according to NADCA or other appropriate guidelines or standards.
In addition, the black dust was found in most of the heat registers. He could rub it off on his fingers but did nothing but spray compressed air on it which didn’t make it disappear since it wasn’t loose. Also, in the register in the basement he described the black dust as being oily. The reality of that situation is that I had the AC on until the morning of the service and minutes after he snaked the hoses in my back door it started raining. The basement register had condensation from the humidity all over it. It was not oily but wet. He asked for an old towel and wiped it out. Never saw anything so black – because I never had to clean soot. That is what I have in my ducts. Soot from years of the old coal furnace.

They arrived within the time range I was given, and they even called about 20-30 minutes before arrival, so that was appreciated.   They arrived and started bringing some equipment - A shop vac (yea, like you can buy at any hardware store), a handheld vacuum cleaner, and large vacuum that came in on wheels.  After showing them the locations of all of the vents in the home and cold air returns, the technician (Simon) started going over a few things with me about their plan for cleaning and showing me the dust & dog hair build up in one of the vents.  After showing me that, he started to try to up-sell me on additional services. That additional service was to insert a 'brush' that would agitate the dust/pet hair and allow for the vacuum to get everything out of the vents.
I thought the price advertised at 129.95 for duct cleaning was great and called to clean our ducts. When they came in to do the the job I could not be home and my wife dealt with them. My wife ended up paying 954.00. They convinced my wife that there was 1.5 inches of mold built up on the Evaporators and coils. It is not the money, my wife could not go to the basement to witness the mold build up or the coil fouling. We have not cleaned our ducts for at least 10 years. The last price we paid for our duct cleaning was 150.00. My concern is that they told my wife not to turn on the heat for 2 hours due the strong chemicals they used to kill the mold. Are these chemicals approved as safe?

This is to Blueberry who.wrote.about home rental dust problems on 12/ 06/2016. If you’ve been there 13 years.your landlord has made enough money to have those problems repaired.I would call your city property standards dept. And let them know what.conditions you are having to live.There is no excuse for living in those conditions when most problems like that are easy fixes.Especially if your kids are getting sick. Tell your landlord your.calling City Health Inspector if he doesn’t fix.the problems.
Demonstrate visible evidence of microbial growth in your duct work. Some service providers may attempt to convince you that your air ducts are contaminated by demonstrating that the microorganisms found in your home grow on a settling plate (i.e., petri dish). This is inappropriate. Some microorganisms are always present in the air, and some growth on a settling plate is normal. As noted earlier, only an expert can positively identify a substance as biological growth and lab analysis may be required for final confirmation. Other testing methods are not reliable.
Air duct cleaning service providers may tell you that they need to apply a chemical biocide to the inside of your ducts to kill bacteria (germs) and fungi (mold), and prevent future biological growth. Some duct cleaning service providers may propose to introduce ozone to kill biological contaminants. Ozone is a highly reactive gas that is regulated in the outside air as a lung irritant. However, there remains considerable controversy over the necessity and wisdom of introducing chemical biocides or ozone into the duct work.
We are a hvac company that provide air duct cleaning service are minimum charge $400 to do a proper air duct cleaning with 2 techs avg 3-6 hours that includes sanitizing. I get phone calls all day about the $99 your not going to get much of a cleaning for that price it for them to get there foot in the door and up sell that the only way for them to stay in business. Just from my 15 years of duct cleaning experience.
The Antimicrobials Information Hotline provides answers to questions concerning current antimicrobial issues (disinfectants, fungicides, others) regulated by the pesticide law, rules and regulations. These cover interpretation laws, rules and regulations, and registration and re-registration of antimicrobial chemicals and products. The Hotline also provide information health & safety issues on registered antimicrobial products, product label and the proper and safe use of these antimicrobial products.

Simon explained the entire process in detail and took the time to show me what they were doing, how they were doing it, and the effects.  In his initial examination of my air duct system, he discovered dust/residue from when the house was built, such as drywall dust.  This was in my air system, and I was shocked.  Not only did they thoroughly clean out all traces of this built up layer of contaminants, but showed me "before and after".  In addition to completely cleaning the air duct system throughout the house (believe me - the inside of the air ducts looked brand new), they sanitized the entire system and then deodorized it.  Halfway through the process, they took my $100+ air filter outside the clean it.  I was both angry and amazed at the size of the dust balls on my filter.  The air ducts were beyond filthy, and simply having the best air filter did nothing for the coating inside the air ducts.  Now you would think after all this education on my part and work on their part, we would be through.  No.
A study done by U.S. Environmental Protection Agency researchers measured dust levels and HVAC system efficiency in test homes during a one-week period during the cooling season and found duct cleaning did not significantly improve dust levels or system performance. Based on that report and other independent research, the EPA’s official advisory on duct cleaning concludes:
I called a company name “GREEN RHVAC” with their $29.00 one system air duck cleaning. When the guy came with a truck I asked him to tell me how much he will charge and he said that if he gave me price and I didn’t want the service then he would charge me $89 or he would tell me how much he charge me after he finished the work. I immoderately sense that I made mistake to call him to my house. To cut my lost I asked him to give me the price and it was $1600 for two systems house. I paid $100 to him for my lesson to learn and search online to find this site is very helpfully and I should do it before to call anyone for air duck cleaning.
My vent covers have lots of mildew. They look bad! I live in a very humid climate in a condo. The handyman here has offered to take those down, wash them, sand, & then spray paint them with a mildew resistant paint. He said that he will leave them off overnight to dry. I am wondering if this is safe to breath the AC blowing out into the open all night??. ! Guess it is better than the mildew!?
Moisture can enter the duct system through leaks or if the system has been improperly installed or serviced. Research suggests that condensation (which occurs when a surface temperature is lower than the dew point temperature of the surrounding air) on or near cooling coils of air conditioning units is a major factor in moisture contamination of the system. The presence of condensation or high relative humidity is an important indicator of the potential for mold growth on any type of duct. Controlling moisture can often be difficult, but here are some steps you can take:
Hi guys if your not convinced yet that duct cleaning is a waste of time. I’m a HVAC business owner install heaters and air conditioners. Simple facts if you have an old system get a new return air fitted with a filter it will catch all the dirt and dust. If you still have as many do black flecks and stuff coming through it is the lining inside your ducting that has perished. So somewhere you have a hole or very old ducting. If you had rats etc its a hole somewhere. To clean, stick your vacuum in the outlet and push the hose as far as it will go this gets 99% of toys and coins fur and alike. Think about it if the object is not heavy it will come out the duct when unit is on. Service the heaters or air con units but not the ducting. I would go further to say that duct cleaning actually damages the ducting in my opinion.
And if you have flex duct and/or fiberglass ductboard in your home- the last thing you want is a big brush or anything abrasive running through it. Even high-pressure air can erode ductboard so I wouldn’t clean it with anything. If it becomes contaminated, get rid of it and install real ductwork. If your ductwork is accessible in the basement – the best thing to do is take it down and manually clean it if it’s full of junk. It’s not going to cost a nickel more to do that than to pay $500-1000 for a ‘duct cleaning machine” AKA big blower and vacuum – to do the job.
I am 79 years old, bought a condo & spent a lot of money on it. this winter my first bill was 450.00. had my furnace checked out, which is on the roof. it was old rusted out & leeking oil. i talked to owner & had new unit installed. they came out to clean ducks & they were split & worn out. there is no crawl space because theres a unit above me. my real estate lady or this company will not help me fix this problem.

As I type this, I am having my ducts cleaned. About 30 including returns and the furnace. $543.00. I am watching the team do it and can see the clear vacuuming tubing and how dirty it has become. I like the gentleman’s comment on “stick your head in your vacuum and breath”….I get it. The team showed me the machine and it’s filtration system…and they will show me it again after the cleaning. However, like I said before, I am actively seeing the tubing that is clear before they start and how dirty it is once they begin and continue cleaning. Reputable company and not a “fly by night” coupon service. People don’t be so cheap, that is your problem.
The Canada Mortgage and Housing Corporation (CMHC), a government agency, conducted a study in the 1990s to investigate two claims: Duct cleaning makes indoor air healthier; and it reduces energy costs by improving airflow. After testing 33 homes in Montreal before and after duct cleaning, the study found that there was no significant improvement in air quality and that duct cleaning alone did not improve airflow or energy efficiency. In some cases, measured particle levels actually increased immediately after a cleaning. In other cases, particle levels decreased immediately after cleaning but returned to previous levels within weeks.

Air duct cleaning companies are responsible for eliminating dust and other potentially harmful elements that can build up inside the air ducts of your home's cooling or heating system. If you need your air ducts cleaned, you may want to seek an air duct cleaning company that has specific knowledge, qualifications, and experience to ensure your home is properly cleaned and left uncontaminated. This article provides details on how to best choose an air duct cleaning company.

On the other hand, if family members are experiencing unusual or unexplained symptoms or illnesses that you think might be related to your home environment, you should discuss the situation with your doctor. EPA has published the following publications for guidance on identifying possible indoor air quality problems and ways to prevent or fix them.
