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!
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.
How exactly do you expect to kill or remove mold without it ? You can’t even clean your hvac systems coils without moisture of some type ,if you use a steam cleaner you can literally clean the whole system minus the electronics . You should do more research and possibly talk to people who do the work before posting , but don’t listen to me i only have a class A contractor license ,epa license , install /repair hvacs , rent and flip houses for a living .
I was told that 15 out vents would be cleaned and one main vent. the guy came over and gave me an estimate of $500. I had acquired a groupon for $49. the guy said just doing the out vents and one main vent would accomplish nothing. Now I am in dispute with the groupon people for a refund which they won’t give and have to go ahead and waste the money and let them do it. Is their doing the 15 outvents and one main one going to accomplish anything?
He proceeded to clean each heat register by removing the grille and blasting it with an air pressure hose toward the duct opening thinking that the dust would magically be sucked inside. In one room this caused a ceiling smoke detector to go off because the excess dust fooled it into thinking there was smoke. I put my hand in front of a register he wasn’t working on and could hardly feel a suction. Although we discussed how I open and close damper doors, I realized later that he never checked, opened or adjusted them during the cleaning. He could have closed all but the one he was working on in order to increase suction results. His next step was to blast air into the duct and then attach a “squid-like” device that slapped around inside the duct as far as he could reach. This is important! In a newer house, ducts have long straight runs from the furnace. In older houses like mine they can turn and twist. In fact, the duct we have a problem with runs straight up from the basement inside a wall and turns 90 degrees into a soffit for three feet then into two 90 degree turns to get into the floor joist area for another two feet and finally a 90 degree turn up to the second floor register. When he cleaned this one he could only get three feet into the register with the hose or squid because of the turns. That was the case with most. Hardly what could be described as a decent cleaning.
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.
You may be familiar with air ducts that are constructed of sheet metal. However, many modern residential air duct systems are constructed of fiber glass duct board or sheet metal ducts that are lined on the inside with fiber glass duct liner. Since the early 1970's, a significant increase in the use of flexible duct, which generally is internally lined with plastic or some other type of material, has occurred.
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.
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.

Furnace cleaners are mostly young men, I know this, I have been one for 15 years or so……so heres the truth, if there are any allergies, children, older people with health issues, we are GOING to make money. do not tell the company you have hired about any health complication. they are salesmen. and they don’t care about you. or your money. make sure they do a good job, then kick them out. you don’t need all the bells and whistles they wanna sell you. any idiot can clean duct work, like I said, I am one of them. I am very good at it, but I don’t have the back bone to sell a widowed old lady a humidifier that she doesn’t need for 500 bucks, overall, if you think you need this service done, which you probably don’t, get it done, do not spend anything over 300$ and do not do it again for at least ten years.
3/8/2019Thank you for your feedback.  Yes, we were late, and we apologize for that.  Sometimes things happen, unfortunately.  However, it was not no show, no call.  There was a technician in your home today.  He began to take the vents off.  You advised him since they were behind schedule, he would have to leave and the service could not be completed.  He then put the vents on and left.
Read before purchasing Groupon! The Groupon offer seems like a great deal but it only includes a maintenance cleaning and not a full cleaning. They basically vacuum the vent with a shop vac. I had to argue with the techs just to get the dryer vent cleaning that is supposed to be included. When I called the office about it they said it was up to the technician to include the dryer vent cleaning but it wasn't automatically included. When I read the fine print on Groupon to her she said Groupon has worded it wrong and won't change it. Very deceiving "deal".
My wife and I are suffering from allergies. We have lived in this house for 37 years and just found out that the A/C ducts need to be cleaned. We had a company one and do the job, but come to find out all they cleaned was the registers and boxes. Their house was to big to go in the duct and we are still getting dust all over the place. I have been looking for a good roto brush so I can do it myself, but all I can find are companies that sell equipment for a high price. I do not want to start my own business, I just want for my wife and I to breath better and keep from getting sick / also not have to dust twice a day. Please can you help. Thank you.
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.
In addition, the service provider may propose applying chemical biocides, designed to kill microbiological contaminants, to the inside of the duct work and to other system components. Some service providers may also suggest applying chemical treatments (sealants or other encapsulants) to encapsulate or cover the inside surfaces of the air ducts and equipment housings because they believe it will control mold growth or prevent the release of dirt particles or fibers from ducts. These practices have yet to be fully researched and you should be fully informed before deciding to permit the use of biocides or chemical treatments in your air ducts. They should only be applied, if at all, after the system has been properly cleaned of all visible dust or debris.
