Is duct cleaning worth it? There is not a yes or no answer that suits everyone. On an Air Force base, the system was not air tight and there was leakage around the filters. The system got dirty. A professional company was called out. The Duct was big enough that a technician could go inside the metal duct and clean it. There was a new Air Handler installed and things were sealed up better. in this case it was worth it.
A thorough visual inspection is the best way to verify the cleanliness of your heating and cooling system. Some service providers use remote photography to document conditions inside ducts. All portions of the system should be visibly clean; you should not be able to detect any debris with the naked eye. Show the Post-Cleaning Consumer Checklist to the service provider before the work begins. After completing the job, ask the service provider to show you each component of your system to verify that the job was performed satisfactorily.
A small number of products are currently registered by EPA specifically for use on the inside of bare sheet metal air ducts. A number of products are also registered for use as sanitizers on hard surfaces, which could include the interior of bare sheet metal ducts. While many such products may be used legally inside of unlined ducts if all label directions are followed, some of the directions on the label may be inappropriate for use in ducts. For example, if the directions indicate "rinse with water", the added moisture could stimulate mold growth.
I had them out to clean the ducts, exhaust fans, and dryer vent in my 54 year-old home yesterday. They showed up a bit early and took their time to ensure that all the grunge was gone. I must say...they really earned their paycheck with this place! The father and son duo worked together to remove and clean the register covers, ream out the ducts and vents with a big furry brush/vacuum unit, and vacuum up the mess. They stated that I had the dirtiest ducts they had encountered in 15 years, and took over two hours to tidy them up, finding nails, copper pipe and assorted detritus and emptying the vacuum bag three times in the process. They were here over 2 1/2 hours, yet charged the fee they had quoted me on the phone, as promised. It was not the cheapest price I have seen, but it seemed fair to me. 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!
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.
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.

I turned on the AC when he was finished and immediately saw black fuzz balls the size of marbles come out of several of the registers. He said that was expected since everything was shaken up. So much for describing the service as cleaning. I paid him and sent him on his way. I cannot imagine that this type of service is worthwhile in anything but a new house. Apparently in old houses such as mine I can expect that using a whole house humidifier in the winter followed by a great AC can loosen the soot. Maybe this is to be expected for the first few weeks of summer each year. I now have lined the inside of the registers with cheesecloth to catch the fuzz. I’ll see if it stops after a couple of weeks.
I noticed a lot of negative feedback, though unfortunately there are many dishonest companies out there. I currently work with a company that cleans duct work and we DO NOT use any scare tactics or up sell services or equipment. Once every 10years of course there are exceptions. We clean supply, returns, air handler, housing, motor, and fan. Though be discerning when qualifying anyone to work in your home. I would ask for REAL REFERENCES to contact.
They were ok.  I had another group that came out that was much more thorough.  When I asked them to come out, they've always been good about that.  I make the appointments, all of them.  All of them, I make the appointments.  They were ok.  They cleaned the ducts.  But I've had others come out from Angie's List that have been much more thorough.  It's all on my terms.  Other people came out and they were much more thorough.  I would have given the other people an A.  They didn't take the ducts down.  The other people took the ducts down, they cleaned the vents and the whole bit.  They said that they could just do it like this and it works well.  I thought good, fine whatever.  It was positive that they came out on time.  They were very nice, they did their job, like I said, they weren't as thorough.  They cleaned my vents, but the other people that came out before, they took the vents out, they washed the vents, they cleaned every vent.  Whereas these people came in, they took the vents off and go I can suck all of his through these three vents with one hole.  And I'm sure they were right on that, but the other people did it differently.  I would not use them again because of that.  To make it better, clean out each and every vent and to clean the vents themselves.  The other people came out and they cleaned every vent that was exposed and they would go in and they cleaned out every vent.  Each one was cleaned out, not one vent will clean out three.  That kind of thing. Price was good.  I know you guys charge a fortune.  You take 40% of what they make.  I've learned that from a couple of them.  That's extreme.  They were all fair.  The prices were all fair.  But I felt bad that Angie's List took 40% of what they did because they did all the work and Angie's List took 40% of their profit, or their cost.  Now you're aware of it.  I've had three or four of them say that to me, and they said, well, we're not complaining because they keep us busy, but you know, that's not fair.  That's too much.  Everything's fair.  If I didn't like the price, I wouldn't buy it.  When the other guys came out, they did every single vent and they didn't.  I really don't like the fact of putting somebody down.  That's the way I am.  They did the work, they did what they felt they needed to do.  And it was different than what I've had in the past.  And I have allergies and all that stuff, so I really want all that junk out of there.  But, I wouldn't put them down.
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...) They refused to refund my money, so I'll be filing a small claims suit. AVOID these scammers. I'm not sure what 'work' they even did!

Just had my air ducts cleaned. They used a high pressure air hose in all the heat ducts and cold air returns. He showed me the stuff that came out, the reason for the duct cleaning was the fact that I had a problem. With rodents. There was quite a few mummified rats and mice, and he said I wouldn’t have to have them done again unless I incur another problem or have renovations done. Cost me 345.00 for a 2 storey large old home. Not a bad price as I had them done when I moved in 28 years ago and it cost me 500.00. Lots of dog hair, toys, balls and assorted goodies came out as well. Took them 2 hours. I did have sanitizer put in the ducts because of the dead rodents.

Had our ducts cleaned late April, 2016. Sodium Chlorite was sprayed into ducts after cleaning. Ever since, we have been bothered with eye and nasal passage irritation because of a “chemical” and “musty” odor. This odor is present whether or not a/c is on.) We are told the sodium chlorite (“EnviroCon, manufactured by Bio-Cide International) is used in hospital and nursing home settings and is not hazardous to health. The air duct company’s suggestion is that they come out and spray even more sodium chlorite…we absolutely don’t want this done! Have had various other recommendations about what we need to have done to remedy our problem. We will be unable to stay in our home if a resolution cannot be found. We’d be willing to replace the ductwork if necessary. (One professional suggested that the cleaning may have “knocked something loose” inside the ductwork and that is the source of the irritant.) This home was built in 1920…no idea when the present ductwork was installed. Any suggestions would be appreciated.
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

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.
