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!!!
I’m having my duct work cleaned this Saturday. Have a coupon for $49 through Amazon. Job normally $249. Had my basement remodeled about 18 months ago. The contractors were very thorough at blocking the vents, as far as I can tell. The offer is for HVAC and dryer vent cleaning. My house is 11 years old. I figured, $49 is not much. I appreciate your tips on not getting talked into any additional service, not to use solvents to clean, the certification information and before and after pictures. Very useful and I’ll be sure that all I spend is the $49 for the voucher.
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.
The best way to ensure indoor air quality and avoid replacing your A/C system is to clean your ducts. Duct cleaning can be as simple as dusting out the vents or something more in-depth like having a professional look through them. While it sounds daunting, what you gain in keeping them clean is much better than the initial cost. Need help finding a duct cleaning service near you?

“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.”
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!
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.

How often you should clean your air ducts depends on your situation. If you or someone in the home has asthma or is acutely allergic to certain airborne materials or pollen, regular duct cleaning may be helpful. The Environmental Protection Agency doesn’t have an official position on the necessity of air duct cleaning unless the ducts have been contaminated by rodents, insects or mold, or you are aware of particles blowing out through the vents. The EPA recommends you have your air ducts cleaned on an as-needed basis. The National Air Duct Cleaners Association (NADCA) suggests having air ducts cleaned every three to five years.


I purchased a Groupon to have the air ducts cleaned at my home by Best Air DC here in Cincinnati. When I called to redeem the deal, I was surprised to learn that I had to make the appointment 5 weeks out because they had no availability. I didn't think much of it since they had the Groupon deal out there. After the service, I've now realized they have deals out on at least 2 other "discount deal" websites. and the funny thing is they have different regular retail values - $229 & $289 value...for the exact same work! 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 was hesitant to have him do that for the price he quoted me. It would have been an extra $275+ for additional cleaning!! I certainly wasn't prepared for that, so I declined the offer. After his assistant started to use the shop vac to get some debris out of the vents, he came back in and said he was just on the phone with the office and he can lower the price of the additional service for me. He wrote up an estimate for me and said that I could call him if I'd like to do the service. 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. To make things even more interesting, I called their number this morning to do some investigation on what they actually do. After I revealed to the girl I had the service done a day prior and that my technician, Simon, didn't clean them like it should be done she drops a bomb on me. Simon is actually the owner!! The whole time, he is telling me that he is on the phone with the office to see if the can get me a better price on the additional cleaning, he is basically full of sh!+. An owner doesn't need to do that - he is just pulling a bait & switch on me. A few positives - Simon & his co-worker were very nice. They did clean the vents, but certainly not the way they should have been done. It saved me from getting my shop vac out and getting a little dirty to do it on my own. He gave me a few tips on making sure I get good air circulation to the 2nd floor of my house. Be very careful, and definitely consider going with a different company if you want your air ducts cleaned. They were in & out in a hurry, which leads me to believe they kind of half a$$ed the work. They're just like a restaurant that turns tables so quickly that the service really lacks. Save your $49 or $59 for the discounted deal and put that towards the cost of a company coming out and doing an actual good job.
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.
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 spent a lot of time reading all these posts and frankly I can’t believe the way some people think. 1. If there is dust and dirt of any kind in my HVAC system I want it out, the mentality that it can stay there and it’s fine is fulish as the system turns on and off microscopic particulates will move in and out of your living space and you will definitely breath them in. The air quality of your home or office will only be as clean as the system that produces it. We don’t not clean things simply because we can’t see them, it’s what we can’t see that can do the most harm. Dust will build up in a system fairly quickly and will get damp at times allowing mold to grow and mold releases spores without any movement as part of its defense meconisam so don’t tell me that when your system turns on it won’t blow the spores out into the living spaces of your home. A build up of dust will cause failures to your system over time, equipment that works harder to do its job will run hotter with more strain and this will lead to brake downs and until then the system will run less efficient then it should. The system was engineered to move a certain volume of air through a specific duct size, when that duct size starts to become narowed down with dust build up your system has to work harder to move that air this is why you will end up with a loss of efficiency and eventually breakdowns or failures. I have seen systems develop a significant amount of dust build up in as little as two years, just look at how fast the filter gets clogged up and it isn’t all that hard to believe. As for all the scams that are out there they hurt the industry because people can’t decipher between them and the legitimate companies, BBB is helpful. Recommendations from HVAC contractors will be a good resource and a good company will provide a written estimate with a complete brake down of what they are going to do and why, most of which is comen sence once they explain it to you, then if you spend about 5 minutes watching them once they are set up you can see they are doing what they said they would do and let’s get real would you do a job that should take approx 3 hours per system for $29/$39/59 or something close to that, if you think you are going to get a good job from a comp that has to make money at that price you shouldn’t be mad at anyone but your self for trying to get quality work at a scam price. If it’s done right it will be very beneficial and depending on the size of your system and where you are in the world it’s going to cost you approx $300 to $600 per system large and or older systems may cost even more. Remember a quality job isn’t wasting money but a lousy job is, even if it’s only $29. I’d rather spend $600 on a quality job then $29 on a lousy job!! Good luck..
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.
I guess I should present my credentials first, I am a 30 year veteran of the heating and cooling industry. I started at the bottom and have participated in every area of the trade. Installer, service, maint. Ownership, rep, territory manager and so on. A forced air duct system is a large vacume. Like your vacume it has an air intake (return air) and an exhaust (supply registers). A filter just like a vacume (located next to furnace or air handler). Now I want you to visualize something. Put your head inside your vacume cleaner and breath. Get the picture? This is what your duct work looks like. Do you clean your vacume when it’s dirty? If it’s full and the filter is dirty you lose performance and it starts poluting the air you breathe. It’s common sense. I recommend hiring a duct cleaning outfit that you have researched to be honest, background checked, drug tested, insured, and highly recommended by your piers in the area. The service is a necessity, but like everything, it should be done by a qualified company.

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?
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!
Maybe I took him to literally but I am pretty sure cops wont show up to ensure that my duct gets replaced. He said it would be over 1000 dollars to replace the ductwork if that is the case. Now, I spoke to a friend who did 2 ductwork lines on his own in his attic and he said it was like 15 dollars for the plastic wirewound tubing to create new ducts. Should I cancel that appointment and just do the work on my own? I feel like I’m a chump or lazy for considering paying someone to do this work.
Here in Frisco, TX…just had a tech come out to clean vents. I used a 30 bucks groupon for “complete vent cleaning”. He told me I have 3 AC units and groupon covers only 1. I told him to do the unit upstairs where the kids sleep. He decided on his own to do the downstairs unit. I yelled at him why he is not doing the unit I told him to do! He said they are all connected. I will clean two for you for the price of one… Oh really?
The original furnace was a coal fired “octopus” design which had no blower to circulate the air but relied upon warm air rising to distribute the heat. That also means that the system breathed air in from the basement and most of this type did not have a cold air return system. At some point (probably in the 1940’s) the system was upgraded to a forced air gas furnace. The upgrade included replacing the 12″ diameter air ducts exposed in the basement with 6″ ducts and a cold air return system of ducts from the two (only two) air returns on the first floor.
“Ideally, the inside surface will be shiny and bright after cleaning. Duct cleaning may be justifiable to you personally for that very reason: you may not want to have your house air circulated through a duct passage that is not as clean as the rest of the house. However, duct cleaning will not usually change the quality of the air you breathe, nor will it significantly affect airflows or heating costs.”
Another sketchy claim made by most duct-cleaning operations and their trade association is that dirty ducts and equipment overburden heating and cooling equipment, which wastes energy. Again, it intuitively makes sense that a cleaner system will run smoother and last longer — after all, that’s why we and HVAC-equipment manufacturers and repair services recommend that you regularly change your filters. But the page “Benefits of HVAC Cleaning” on the National Air Duct Cleaners Association (NADCA) website stretches this benefit too far by stating: “According to the U.S. Department of Energy, 25 to 40 percent of the energy used for heating and cooling a home is wasted.”

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.
The same holds true for the evaporator coils inside your home’s cooling system. Evaporator coils cause condensation, dehumidifying the air before it circulates through your home. Condensed moisture can cause dust and other particles to stick to and build up on the coils. Also, cleaning the collector pan (and the drain spout in the pan) beneath the coils ensures dirt doesn’t build up and get drawn into the system. It also prevents water from accumulating on and beneath the coils, which can cause mold problems.
Their crew arrived promptly at 7:00 am. Carlos explained what each crew member would be doing. They increased the insulation in my attic. They also discovered that the ducts had been attached to the vents with plain duct tape. The duct tape had become gooey due to heat and had slipped off the vents in many places. This allowed out side air and dust to enter, spreading dust out of the vents. It also allowed cooled air to escape into the attic. The corrected all of the duct work connections. Jeff came to check the work upon completion. He ran tests to verify that the work had been done correctly, and he replaced all of the "regular" light bulbs with cal bulbs. All of the work was done quickly and neatly.
Although duct-cleaning operations may insist duct cleaning is essential for your health, the evidence does not support their claims. Companies that perform duct cleaning often advertise health benefits or suggest duct cleaning will lower your power bills by improving your system’s efficiency. Some ads even use language like, “Studies have shown . . . ” but no data back up these claims. Even if your ducts are dirty, cleaning them probably won’t provide any measurable benefits. In fact, the little independent research performed on duct cleaning indicates that the process stirs up so much dust that it creates a bigger problem than it solves.
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.
