On the other hand, if a service provider fails to follow proper duct cleaning procedures, duct cleaning can cause indoor air problems. For example, an inadequate vacuum collection system can release more dust, dirt and other contaminants than if you had left the ducts alone. A careless or inadequately trained service provider can damage your ducts or heating and cooling system, possibly increasing your heating and air conditioning costs or forcing you to undertake difficult and costly repairs or replacements.
If you suspect a mold problem — either because of visible growth or a musty smell consistently coming from supply vents — cleaning ducts won’t do much good if it doesn’t eliminate the mold. Mold begins with a moisture problem, and the ducts themselves are unlikely to be the source. The most likely culprits are the cooling system’s evaporator coils, which your heating and air-conditioning contractor — and most duct-cleaning companies — can inspect and maintain. Leaky return ducts can also introduce moisture. Again, if you suspect a mold problem, consider having a service company inspect the duct system for leaks.
I purchased an Air Duct Cleaning from this company through Groupon. When I originally scheduled the latest cleaning it was Nov. 8, 2017. They finally showed up today March 8, 2018. When they arrived they got set up looked in the vents with there camera and said it looks like you will need an Air Duct Cleaning; we will be vacuuming today. Best Air Rep: The cleaning after looking inside will be $200-$500 additional. ??? I was floored. The next statement from the Best Air rep was: Who did your last cleaning? "They did a horrible job." What he did not realize is that they had done the last supposedly Air Duct Cleaning on May 3, 2016.
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.
Chemical biocides are regulated by EPA under Federal pesticide law. A product must be registered by EPA for a specific use before it can be legally used for that purpose. The specific use(s) must appear on the pesticide (e.g., biocide) label, along with other important information. It is a violation of federal law to use a pesticide product in any manner inconsistent with the label directions.
We are all getting migraines several times a month. I have asthma but not ever as bad as it has been and my 2 year olds dr just informed me she potentially has asthma too. We all get sinus infections regularly and eczema and contact dermatitis. None of us have been this way until recently in our apartment. A roof leak with mold was repaired recently mold was sealed off not removed. We also had lead paint removed from a few window trims this year. I wasn’t here to see if they covered the vents. We had mice too. I vacuum everyday we have hardwood floors no one wears shoes past the font door and I’m getting over a cup full of dirt every time I vacuum. Dust on everything daily. White dust. It’s a 4 room apartment with 1 intake. They are filthy from what I can see when I change the filters. The filters are black after a few months. I feel bad to ask the homeowner to get the system cleaned, can’t afford to move (we live in the city & it’s expensive). I am going to try the shop vac to remove what I can. Any experienced hvac people please give your opinion. Should I just get it done and pay for it myself? We have lived here for 13 years. It’s never been cleaned since ive been here. Is it something I can do with a shop vac? Can i use a wet rag to get the powder dust on the inside of the vents off. One vent has what looks like chunks of dry wall or thick paint sitting in the vent and none of the vents screw into the wall, the screws just fall out. No one ever reinforced the area so the wall just basically crumbles. Kind of useless to spend the money on filters since the air and dust just blows out around the sides of the vents and one of the vents just falls right out of the wall when the heat is turned on. I don’t know why the owner doesn’t fix it. He’s been here to replace filters and saw the condition.
Had duct cleaners here coupon for 40.00 for complete home I was not here but my husband was. I told my husband that they will prolly ask for more money and I was right. 85 extra to do duct cleaning which I pled because my dryer vent was full of animal hair extensions then for 600 to clean a/c coils I said no. Just do what the coupon said. Do your homework be 100 steps ahead of these con men rember they con people all day long and know the ans to your objections
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?
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.
Although much of the energy used to power heating and cooling equipment is indeed wasted, that waste is because of inefficient equipment, lousy insulation, leaks around doors and windows, and unsealed ductwork. While there’s some benefit to cleaning and maintaining HVAC equipment, that benefit is relatively small, and little energy waste is attributable to dirty ducts or equipment.

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!
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.
