Since most states and municipalities don’t license air duct cleaners, you need to check their professional credentials instead, such as NADCA membership. EPA recommends all duct cleaners follow NADCA standards. Member companies must keep at least one technician on staff who has passed a NADCA test. “They have to pass rigorous testing to earn the certificate, and our code of ethics is very important,” Vinick says.

My best advice has always been that a proper duct cleaning is a valuable investment when moving into a home (new or old), after major renovations and if the ducts have never been cleaned before. It is unlikely that there will be increased air flow, as finding major blockage is unusual, but this will eliminate this as a possible concern if there are air flow concerns. It is also true that the "dust" that is cleared out will most likely never have been distributed through the house unless there has been some work done on the ducts. What is cleared out will be pet hair, toys, clothes, construction material, and biological material (small carcasses and/or feces). Once a proper cleaning is done a follow-up is rarely necessary, but up to the home owners discression.
Well, I had the cleaning done. The handler is definitely much quieter. It was explained to me that with the coils clean, the condensation will be able to sweat off instead of sticking to the dust and dirt, therefore the humidity (lots of humidity in florida) will be removed better. I feel as if it was worth it, but, I will definitely change that filter every 3 weeks or so from now on. I don’t want to pay that cost again.

I hired duct cleaning company out of "Service Magic" website. I did not realize the name of his company was Duck cleaning of Central Florida...that should have given me a hint.. The guy did a very poor, incomplete job, and ruined a closet full of clothes when he sprayed up to clean a vent instead of taking it down and cleaning it outside. He left me with more than 1/2 dirty vents and ducts, did not do the air handler in the garage and failed to fog the system. He spent 6 useless hours at my residence and now his insurance is denying coverage..very disappointed in Service Magic....


I paid $49 for a groupon. When the guy came today, he did an inspection first and said the ductwork first needed to be treated for mold; $348 for a spray that would last 8 months or $680 for an UV light purifier that would last 2 years. Also, the furnace needed to be cleaned for another $260. When I told him to just clean the ductwork, he said I would owe an additional $305 because the groupon was only good for 1 return and I had 2. I sent him packing with no services performed. Thankfully I am only out of $49! I will complain to groupon.


No one has addressed mfg homes and doesn't seem any of the comments are from people in So CA which of course does make a difference as my dust comes from the outside not from the vents. My windows are open pretty much 365 days a year. Secondly mfg homes don't have basements or attics I keep mine clean with my vacuum as they are only about 2 ft deep. I purchased my home 10 yrs ago and it is a high end home but have never had a problem. I clean my furnace filter about twice a month as I have cats and most everything in there is cat fur. I am not saying they don't ever need to be cleaned but I am questioning mfg homes, I also clean my own filters in my AC unit outside as the HVAC guy told me too he QUATITY they would sell. I use this same company every year now for my tune up and inspection which takes them about 10 minutes. Not a bad return for them and I don't mind the $79 fee. If anyone has more info than this on mfg homes please let me know!
I've been in business in Florida for 25 years and purchased a $12,000 duct cleaning system 4 years ago. In the last four years I've cleaned 5 duct systems charging around $400 each. Not a very good return on investment. What I have been doing most the time is I get a call by someone panicked because they called some low priced company to inspect their system and were told they have dangerous black mold. Then they call me to have a look. Most the time they don't have mold, ducts look very clean. However the coils are dirty and the inside of the air handler cabinet needs cleaning. Keep in mind not every system can handle supper high efficiency filters! These filters can block air flow quite a bit right out of the package. Many older systems can't handle pleated filters due to increased static pressure. "Back rooms with low air flow". I have taken many hours of classroom study on indoor air quality. Never got any certification because I don't want to pay another organization dues yearly. I think the problem with duct / system cleaning is most people are suckers for low priced scams that are rip- offs . People call me all the time and ask how much? When I tell them average $400 they hang up. I know I do the job correctly and honestly, and they are going to get racked over the coals by the scam artists by calling $79 whole house duct cleaning guys. People need to check internet, angies list and BBB reviews. But keep in mind even reviews need to be sifted through your rational person filter.

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.
The fact is if they are dirty why not clean them. As for the Dr’s comment about if it is not disrupted it is fine. As a pet owner sometimes un disrupted pet hair will sit in the corner of a room or under a counter un disrupted but I still clean it when I notice it. Just because you cant see it doesn’t mean you should leave it there to collect more and more. The people that don’t want there air ducts clean either simply cant afford it but would like it done. OR! the crowd that are to cheap.. You should Clean all portions of your house.
Hello, I read your comment and I know it was two years ago but I hope you see my message. I am trying to figure out what to do as I was told that there is some cat odor in the finished basement. I think with the air conditioning running that it may carry odor. The litter boxes are always kept clean. I wonder if odor can be trapped in the ducts, if Air Duct Cleaning could help, but it is quite expensive plus I'm concerned that it may not help. Please elaborate as to why you think it doesn't work that well. Do you have any other advise? Did you work in the field of Air Duct Cleaning? Thanks so much!
I am NADCA Certified Air Systems Cleaning Specialist. Over the years I have learned on simple answer to this questions: there air duct cleaners and there are pretenders. There will be no benefit at all if you use on the very cheap pretender because they will not really clean anything. On the other hand if you call a qualified air duct cleaner with a NADCA Certification you will, like 99% of my customers, report improvement with your respiratory problems, you will see less dust and the job will pay for itself with energy savings and repair prevention.

I purchased a Groupon for cleaning of unlimited air ducts and one return vent for $39. I should have checked into their hours first because they only offer services during normal business hours. So, with no evenings or weekends available you have to take time off work. I asked Groupon for a refund when I realized this and they refused because it wasn’t within the three day window. Then they didn’t even show up or call for the appointment. I called them after they were an hour late and they were going to call the local dispatch office and have them call me back within 15 minutes. I did not receive that call. I called again and was told I would get a call back from a manager. That didn’t happen either. So I asked Groupon for a refund again and they gave me Groupon bucks. When the survey came asking if I was satisfied with the Groupon customer service I said no, I want real money. I got my real refund the next day. Seems to me Groupon should stop dealing with these companies.
If you want to get some of the dust and debris out of your ventilation system, you can mix household cleaners like bleach with water, dip a cloth in the mix and then the wipe out the system. This will remove a layer of the spores, which could increase the quality of air a bit and help with the flow of air throughout the house until a pro can come out.

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 own a small mechanical company. My main work is service and system replacements. I have never been a believer in duct cleaning. The company I worked for before had our duct man come out and do my house. I saw no difference. Preventive maintance is what I recomend. Remove fan and clean, seal fan compartment to prevent dust from being pulled in, filters I install media filters, they are 5″ thick and pleated. I have tested them to make sure static presure was not a issue. Heat exchangers and AC coils need to be cleaned. I will tell you this to do a good cleaning I usually spent 1-2 hrs, When I’m finished I would not have a problem eating my diner on the system. Good filters, clean system and properly tuned up are my recomdation to anyone. I’ve included my email feel free to contact me with any questions. winkcfd@yahoo.com
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?).
