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.

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.

The headache started with a Groupon purchase. Service for an air duct cleaning was purchased and scheduled. When the guy arrived he attempted to say that the purchase was only for a vacuuming of the vents and not a duct cleaning. Despite showing him the groupon he refused to do service. We then contacted Jennifer at this company and eventually got on a three way call with groupon who agreed with us that the service was for a complete air duct cleaning and not just using a hand vacuum to clean vents (something we could do any time). Jennifer has since hung up on my wife twice despite being civil and merely asking for the services we paid for. Unprofessional.

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.
After major damage to a small addition on our home was damaged in the windstorm in May, the insurer’s preferred vendor sanded drywall without taping off the area. They relied on heat from the furnace to dry the mudding compound. They claimed they shut the furnace off while sanding and regardless of whether they did or not, they never cleaned up the drywall dust before turning the furnace back on. I now have drywall dust everywhere and my husband took photos to verify our concerns. They even sanded right above a cold air return. Vents were never covered either. The same company that created this mess is cleaning my ducts today. They have refused to clean the furnace. Their are health concerns for my almost 85 yr old mother who resides with us. I’ve tried 3 times in the last 7 days to escalate to a manager and they will not return my call. They just keep sending it back down to my adjuster. There are many other issues we’ve encountered since May as well. This is a major insurance company who has the resources to fix this mess but refuse. Please help!

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.
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.
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.

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...)

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.
Recent Review: Alex, Mike, and Cisco came out on time. They covered any furniture that might get some dust/dirt on it with plastic. They removed all of the vent and return covers, took them outside and thoroughly cleaned them. They vacuumed out the vents, then went in with a swab covered in sanitizer. They kept performing this step until the swab came back clean. They sprayed sanitizer into the vent system and replaced all of the vent covers. They went up on he roof and cleaned the a/c unit coils. They cleaned out the dryer vent as well. The crew was very knowledgeable and professional. I will definitely be calling them the next time I need my ducts and dryer vent cleaned!
I bought a Groupon for an air duct cleaning and deodorizing for $59. I read all of the fine print and it said "unlimited ducts." When they came to perform the service they said it would cost an additional $200 to cover the entire house. I ended up canceling the whole service and the guy who was there do to the work said he is leaving the company because of issues like this. He said 25% of their customers end up canceling when they arrive to do the service because of the dishonest advertising. Later the same day, the manager called me to discuss why I canceled the service. I told her the Groupon was dishonest and intentionally misleading and her response was, "I don't work on the advertising." I told her that as the manager she has some responsibility for what is advertised about the company and she said, "I just work here, I don't own the company." So apparently the management has no responsibilities at Best Air DC, perhaps that is part of the problem. I will never use them again and hope no one else does either. Save your money!
Very interesting article. I searched articles about services for cleaning ventilation systems. But I have some questions. For cleaning ventilation system used special products for cleaning. Can I know in company manager about, which type of cleaning products they use? Your family members may be allergic in some components. It’s very big problem. And one more problem it’s how to choose the right company in Internet. Sometimes I don’t have much time to find a company in my town and I use the Internet. But I find a lot of company. It is very popular services, for example, Stanley Steemer – https://www.stanleysteemer.com/ or my local not very popular service, for example, AllstatesAirDuctPro – http://allstatesairductpro.us/. Can I understand the company is professional or not, only looking through the website? What must I check on the website? Who has helpful information? I will very grateful for your help. Links I add for understanding my problem. They are random and not for advertising.

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.

“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.”
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.

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.

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.
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.

Recent Review: 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.
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.
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!
We've used this company several times in the past and have always been happy with the service.  My husband and I have allergies, so it's important to us to get the air ducts cleaned.  They cleaned up any dust that came out of the air ducts when they removed the vents.  I called several companies for estimates, and this company gave me the best estimate.
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.
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!
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.
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.

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.

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.
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.

If you are replacing your air conditioning system, make sure that the unit is the proper size for your needs and that all ducts are sealed at the joints. A unit that is too big will cycle on and off frequently, resulting in poor moisture removal, particularly in areas with high humidity. Also make sure that your new system is designed to manage condensation effectively.
