Duct cleaning generally refers to the cleaning of various heating and cooling system components of forced air systems, including the supply and return air ducts and registers, grilles and diffusers, heat exchangers heating and cooling coils, condensate drain pans (drip pans), fan motor and fan housing, and the air handling unit housing (See diagram).
All of the products discussed above are registered solely for the purpose of sanitizing the smooth surfaces of unlined (bare) sheet metal ducts. No products are currently registered as biocides for use on fiber glass duct board or fiber glass lined ducts, so it is important to determine if sections of your system contain these materials before permitting the application of any biocide.
We bought the Groupon deal. One of the techs knocked a pitcher off a shelf in our kitchen during the service and did not tell us about it, he just picked it (and the two broken pieces that came out of it) up and put them back on a different shelf. We didn't discover that it was broken until later that evening. We managed to speak with one of the two guys that evening, who said it wasn't him, must have been the other guy, (and still had the nerve to try to talk us into an additional $250 worth of service with them!) and said he would talk to his boss and have someone call us. That didn't happen. I have called the office several times myself in the two weeks since trying to speak with a manager, and my husband has also called. No one has bothered to call us back yet to address this or offer any sort of recompense for the broken item. Therefore I can't recommend this company to anyone else.
Air ducts for your HVAC are critical for the efficient and effective filtering of microbes from the interior air your family breathes. For this reason, Most people should focus more on the proper cleaning and maintenance of your air ducts at least with equal importance as the filters you buy. 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 discovered Best Air Duct Cleaning LLC though an Amazon Local offer. Simon and his co-worker showed up on time with more equipment and materials than necessary, and I am so glad and appreciative they did! 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. I had researched by HVAC system and saw electronic air filters for over $1000. That was too much for me. But Simon introduced me to a product which uses ultraviolet light to further clean the air going into my home from the HVAC unit, and he gave me a discount because of the totally thorough cleaning I had purchased. This unit attaches to the duct coming after the air filter and comes with a lifetime warranty. Included in that lifetime warranty is a visit every two years to replace elements of this air cleaner, and a free air duct cleaning. Best Air Duct Cleaning provides air duct cleaning, which includes cleaning all your vents in the house outside your house. They repair and install air ducts and associated materials. They also cleaned my dryer vent, which was also incredibly filthy. Simon and his co-worker are intelligent, extremely knowledgeable and patient in their explanations and education to the consumer, and goodness, they are so friendly. I can't praise them enough for the experience and their industriousness. They take indoor pollution and the potential adverse health effects very seriously. The peace of mind I now have knowing all the filth they removed which was invisible to me is worth ten times the amount I paid. Absolutely wonderful people and company.
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.

How exactly do you expect to kill or remove mold without it ? You can’t even clean your hvac systems coils without moisture of some type ,if you use a steam cleaner you can literally clean the whole system minus the electronics . You should do more research and possibly talk to people who do the work before posting , but don’t listen to me i only have a class A contractor license ,epa license , install /repair hvacs , rent and flip houses for a living .

I forgot about a pot of sweet water I had on the stove to boil. When I finally smelled it the kitchen and dining room I=was smoke filled. I mean thick smoke. I opened doors and windows for a few hours to remove the smoke but the smell is still here and terrible. I had to use the AC and that smell started coming out of the vents. Now what do I do? I have COPD emphysema so I have to be very careful about what I inhale. I already have inhaled too much smoke from all of this which has hurt my lungs even more. I can’t afford for them to get worse over this. How can I get the right person to come out and clean the ducts and furnace or is that the only way to remove that burnt smokey smell. The pot never caught on fire but it sure did produce a lot of smoke. I already have replaced the filter on the furnace. It needed it even though it had just been replaced just last week. I need help or really my lungs need help. Who do I call here in Indpls IN.
If there is stuff in the ducts, the fact that it’s laying there and not being blown into the rooms is proof positive that it is hurting no-one. The 5-6 exceptions you cite in this article I’ll buy, but only with the caveat that at least some of those could have been avoided by proper protection (during remodeling for example) – and if asbestos/lead/whatever winds up in your ducts- the remodeling contractor should be the one paying to remove it.
After they left, I was feeling uneasy about the quality of work that was performed. I used a camera to get some video of the vents that they cleaned. They looked pretty good, but then I started to remember how they were cleaning them.  They only used their large, commercial vacuum on one vent.  They also did NOT clean 2 air returns under Negative Pressure like the Groupon said they would.  I did a little research and found that they should have cut open an access point in duct work in the basement and sealed up the vents with plastic to create that negative pressure.

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.


Definitely would recommend. I just bought a house in the Hyde Park area. It is an older house, but I could tell just by looking at the vents that they had not been cleaned in years. I was having issues with my breathing, so I decided to have them cleaned. You have to schedule pretty far out in advance, but it is because they are very busy. They gave me a time window of 8-11 and showed up right in the middle of that window. I opted for the full cleaning and sanitizing because my vents were that bad. The two guys that cleaned my vents did a great job. He recorded the vents before and after and I could not believe the results. He also showed me what had been caught by my filter and sucked up by the vacuum. Would highly recommend to anyone purchasing a home to have this done.

All of you have dentists, you have doctors, you have preachers, you have mechanics. You don’t have to know everything about everything but you have to have people in your life that you can trust. Don’t just open up the phone book and pick a mechanical (HVAC) contractor. Call your friends and family and ask for referrals. There are no black and white (scam or not a scam) answers here.
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.
If I could rate this company a zero I would in a heartbeat. I purchased the service off of Groupon and to say that the groupon was misleading is an understatement. I was at work and my girlfriend was at the house when they got there (keep in mind it took six months for them to be able to get there because they were over booked). They tried to upcharge my girlfriend $250 immediately upon getting there. I told her to put me on the phone and spoke with the guy myself. He said that he would have the manager call me and that he would just start on the service. I received a text from my girlfriend 10 minutes later that the people had left. I never received a call from the manager. They didn't do all vents in the house. All they did was the main floor. It was a pathetic attempt to say the least. I received a call from the customer service representative that told me that the package I received was for a "Air Duct Cleaning with deodorizing treatment" and it was not a "Air Duct DEEP Cleaning with deodorizing treatment" and that is where the additional $250 was coming from. They then told me that if I wanted, they could come back out a week later and explain it to me professionally and also blamed Groupon for the posting to be misleading. The rep bragged about their ratings on review sites. I am guessing that this is taken down soon and deleted by the company. But if I can just save one person's time, money and efforts to better their home with this post I am more than happy to do it. STAY AWAY FROM THIS COMPANY, THEY ARE UNPROFESSIONAL AND WILL SCREW YOU OVER FOR THEM TO SAVE A PENNY.
I have worked cleaning HVAC in my area for almost 5 years. I always do a thorough inspection and cleaning, providing before and after photos. I have completed some jobs where I felt that it was not entirely necessary, but ultimately what the customer wanted. With that being said, I have endless photos of unspeakable horrors. Hotels are usually nasty, post construction mess is certain, pets and kids create lots off debris, bugs congregate and die, then spiders set up and die, I have even had one supply that was nearly plugged with sand!

“Duct cleaning has never been shown to actually prevent health problems. Neither do studies conclusively demonstrate that particle (e.g. dust) levels in homes increase because of dirty air ducts.

Moreover, there is no evidence that a light amount of household dust or other particulate matter in air ducts poses any risk to your health.”
15 vents and ducts cleaned for the firest time since house built in 1968. Charles and his wife came at 8:00 am as scheduled, with their enormous vacuum, conneded it to our system, removed all the vents, plugged them with sponge material and vacuumed the entire system while they scoured out all of the aire conditioneing ducts from end to end with a rotating brush with flexible bristles like a string trimmer that reached all of the crevices in the ducts. While Charles cleaned the ducts, his wife cleanted all of the vents. they sanitized and deodorized the entire system. They finished everything and cleaned up and left just before noon. I examined the ducts after they left and they gleamed like new. $304 well spent and excellent service. I'd recommend them to anyone.
I just had my blower module replaced because my AC coil was frozen over. The underside of my coils had a thick mat of dust because I had never had it cleaned. I cleaned it myself by using a soft brush attachement on a shop vac. The inside of the blower appears to have a white/green growth, and I am sure the ductwork of my 30 year old house can’t be in good condition.
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:
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.
Duct cleaning has never been shown to actually prevent health problems. Neither do studies conclusively demonstrate that particle (e.g., dust) levels in homes increase because of dirty air ducts. This is because much of the dirt in air ducts adheres to duct surfaces and does not necessarily enter the living space. It is important to keep in mind that dirty air ducts are only one of many possible sources of particles that are present in homes. Pollutants that enter the home both from outdoors and indoor activities such as cooking, cleaning, smoking, or just moving around can cause greater exposure to contaminants than dirty air ducts. Moreover, there is no evidence that a light amount of household dust or other particulate matter in air ducts poses any risk to your health.
