Air duct cleaning service providers may tell you that they need to apply chemical biocide to the inside of your ducts as a means to kill bacteria (germs) and fungi (mold) and prevent future biological growth. They may also propose the application of a "sealant" to prevent dust and dirt particles from being released into the air or to seal air leaks. You should fully understand the pros and cons of permitting application of chemical biocides or sealants. While the targeted use of chemical biocides and sealants may be appropriate under specific circumstances, research has not demonstrated their effectiveness in duct cleaning or their potential adverse health effects. No chemical biocides are currently registered by EPA for use in internally-insulated air duct systems (see Should chemical biocides be applied to the inside of air ducts?).

If no one in your household suffers from allergies or unexplained symptoms or illnesses and if, after a visual inspection of the inside of the ducts, you see no indication that your air ducts are contaminated with large deposits of dust or mold (no musty odor or visible mold growth), having your air ducts cleaned is probably unnecessary. It is normal for the return registers to get dusty as dust-laden air is pulled through the grate. This does not indicate that your air ducts are contaminated with heavy deposits of dust or debris; the registers can be easily vacuumed or removed and cleaned.
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.

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.


“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. . . . 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.”
EPA does not recommend that air ducts be cleaned except on an as-needed basis because of the continuing uncertainty about the benefits of duct cleaning under most circumstances. EPA does, however, recommend that if you have a fuel burning furnace, stove, or fireplace, they be inspected for proper functioning and serviced before each heating season to protect against carbon monoxide poisoning. Some research also suggests that cleaning dirty cooling coils, fans and heat exchangers can improve the efficiency of heating and cooling systems. However, little evidence exists to indicate that simply cleaning the duct system will increase your system's efficiency.
i got angies list deal for 109 air duct clenaing, dryer vent cleaning, and furnace inspection, {healthy duct cleaning} i call the company, they arrive on time. did excellent service what ever i purches i got. they give me furnace inspection and the told me that my furnace is very dirty and they offer me to clean that for 250 extra. i paid and i am very happy from this service. i try before 2 diffrent company that i got deal from them as well the just give me estimate and don’t even do the job. so guys don’t spend time if you need deep cleaning just cal this guy the offer free estimate as well.

Quality and price should come hand in hand, a too-good-to-be-true price for an efficient air duct cleaning will not give you the quality that you wanted. To make sure you are getting your money’s worth, check reviews of air duct cleaning companies, certifications from industry since this work requires continuous learning due to new techniques and research breakthrough from time to time. Make sure to shop around and get written estimates first.


The renters in my rental home complained of the dryer needing 2 cycles to dry their clothes. I called out Arizona Air Duct to clean the vent. Well, $75 later the issue is not fixed. I had another company come out. They pulled out a section of the vent to show me- there's maybe half the piping still coated in lint. (I wish i could post pictures here...)


if you do not want to put that dryer cleaner down your ducts (I don’t because if it gets stuck somewhere you will be stuck calling a pro to get it out! anyway what I did was take the furnace filter out for max air flow, and then close off all your vents leaving only one open at a time to clean. This directs all the air from your system only to the vent going to the opening you are cleaning. Then stick the flexible tubing of your vacuum cleaner down a bit into the vent and turn on the vacuum. Then go to the thermostat and turn on the fan only and let the vacuum run for a few minutes. That does a great job and you can do it with or without the brush. When done put a fresh filter in. I only do this for the vents where the air blows out. I would not recommend cleaning the cold air returns this was as you would likely be forcing dirt and dust into your furnace. If you want to vacuum the cold air returns, turn the system off
Do not hire duct cleaners who make sweeping claims about the health benefits of duct cleaning — such claims are unsubstantiated. Do not hire duct cleaners who recommend duct cleaning as a routine part of your heating and cooling system maintenance. You should also be wary of duct cleaners who claim to be certified by EPA. Note: EPA neither establishes duct cleaning standards nor certifies, endorses, or approves duct cleaning companies.

We bought a short sale home buit in 1987.  The home is gross to say the least. I called last week to set the appt. up once I knew we had a close date. They called to say they were running a bit late, which happens with this type of work. They did great work, cleaned up after themselves, very nice men, cleaned all the vents,fans inside and out. I will feel much better bringing my family into a clean home now.

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.


If you suspect a mold problem — either because of visible growth or a musty smell consistently coming from supply vents — cleaning ducts won’t do much good if it doesn’t eliminate the mold. Mold begins with a moisture problem, and the ducts themselves are unlikely to be the source. The most likely culprits are the cooling system’s evaporator coils, which your heating and air-conditioning contractor — and most duct-cleaning companies — can inspect and maintain. Leaky return ducts can also introduce moisture. Again, if you suspect a mold problem, consider having a service company inspect the duct system for leaks.

So I purchased a Groupon to have this service done on my HVAC. I waited like 3 weeks or so since I was not using the heat or AC and I was in no hurry. So, on the day of my scheduled appointment which was 12noon I get a call from their office at 12:05pm that they are running late and they are 2 hours away...How did they manage to end up 2 hours from my house? Odd. Anyway, the girl tells me that they can't make the appointment today and will have to reschedule 30 days from now. What? 30 days from now? I was expecting perhaps tomorrow or the next day, not 30 days from now. This is extremely poor customer service and poor time management. Their leadership team should be reprimanded or replaced. I don't know how this company can stay in business when their business practices are so disorganized and they cannot even manage a schedule efficiently. I would NEVER recommend this company when they treat the customers so poorly. Their front office person should be retrained or fired since she does not have the skills needed to deal with customers. I would go so far as to fire their Office Manager or perhaps the Manager of this company. Well, at least they did not show up and provide poor service as it appears they did in the other customer reviews.
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.
I live in Port Orange, FL. I purchased a double wide mobile home and was saddened to learn that the previous owners were HEAVY smokers! They did a good job “hiding” the smoke smell the day we viewed this place. I did not have a home inspection done unfortunately. My question is: can duct cleaning remove the smoke smell from this place. The ceilings have been treated with Kilz and paint. I personally scrubbed down every wall, floor or surface. I also purchased a ODORFREE OZONE machine. It seemed to remove the odor for a short period of time but my friends are again complaining about the “smoke” odor in my home. The Ozone machine was $400 and I’m terribly upset that it didn’t clean the air as was promised.
Backed by his 40-year remodeling career, Danny served as the home improvement expert for CBS’s The Early Show and The Weather Channel for more than a decade. His extensive hands-on experience and understanding of the industry make him the go-to source for all things having to do with the home – from advice on simple repairs, to complete remodels, to helping homeowners prepare their homes for extreme weather and seasons.
Interestingly, I had this service performed several years ago, by a cheaper company.  Based on the amount of dirt and junk that was removed yesterday, I now have my doubts that the previous company really performed the work.  Yes, I checked  this time!  The owner, John, told me that there is another company working under the same name, so make sure that you are getting the Arizona Air Duct Cleaning Company, father and son team, that is being reviewed here.  Not all these companies  are honest and do what they claim to!
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.
I have been a plumbing/gas/hvac tech for 19 years, before that I installed ductwork in commercial buildings and office towers. As the article states, unless you have undergone some type of extensive reno, or ducts have become contaminated, paying for cleaning is pointless. Its one thing if you have a 30 year old home that has never had a duct cleaning and you can actually see mounds of dust built up , especially in the return side, then go for it. Keep in mind that most duct cleaning companies will only get 80% of the dust , or less at best. Keep in mind that most of the dust in your home is lint from clothes and linens, and skin cells from you and your pets and is constantly being generated. Dust that builds up in ductwork , generally stays in the ductwork. The power of suggestion, scare tactics, up sell!!!

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 purchased an Air Duct Cleaning from this company through Groupon. When I originally scheduled the latest cleaning it was Nov. 8, 2017. They finally showed up today March 8, 2018. When they arrived they got set up looked in the vents with there camera and said it looks like you will need an Air Duct Cleaning; we will be vacuuming today. Best Air Rep: The cleaning after looking inside will be $200-$500 additional. ??? I was floored. The next statement from the Best Air rep was: Who did your last cleaning? "They did a horrible job." What he did not realize is that they had done the last supposedly Air Duct Cleaning on May 3, 2016.

I purchased one of those Amazon air duct cleaning coupons for 49.99. When the company showed up, they removed the vent closest to the air intake and immediately told me I needed $1800.00 for all new duct work. They said they could not clean the system until new duct work was installed. I thanked them and said I would give them a call. The only call I made was to Amazon to get a refund. I know I didn’t need new duct work. Be careful to not fall for unscrupulous salesmen and their pitches and scare tactics.
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.

The bottom line is: no one knows. There are examples of ducts that have become badly contaminated with a variety of materials that may pose risks to your health. The duct system can serve as a means to distribute these contaminants throughout a home. In these cases, duct cleaning may make sense. However, a light amount of household dust in your air ducts is normal. Duct cleaning is not considered to be a necessary part of yearly maintenance of your heating and cooling system, which consists of regular cleaning of drain pans and heating and cooling coils, regular filter changes and yearly inspections of heating equipment. Research continues in an effort to evaluate the potential benefits of air duct cleaning.
