fact is most homes have bad filter racks. when you insert the filter it doesn’t seal well to the sides so some of the air and dust bypass it and end up in the supply ductwork and into the house. Most of the dust in the supply ductwork settles down and doesn’t get blown in the house but some of it does when the blower starts up or when you put a new filter. If you have allergies or other health problems put in an electronic air cleaner, get your ducts cleaned and run the fan as much as you can afford. you can also get an ECM motor installed which is going to be worth it if you want to run the fan 24/7. If you have uninsulated metal ducts take down the ones you can and wash them. Then put them back and seal the joints. Cleaning the ductwork also improves airflow which is important to AC and Heat pump systems for efficiency. An electronic air cleaner will also improve airflow and static pressure because they usually have a much larger filter surface area. An electronic air cleaner also keeps the ac coil clean like new which means better efficiency and no cleaning needed. AC furnaces sometimes grow mold around the coil because of the condensation. Electronic air cleaners should be able to filter mold spores but the best remedy is installing a UV light next to the coil which will kill the mold.
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.
All of you have dentists, you have doctors, you have preachers, you have mechanics. You don’t have to know everything about everything but you have to have people in your life that you can trust. Don’t just open up the phone book and pick a mechanical (HVAC) contractor. Call your friends and family and ask for referrals. There are no black and white (scam or not a scam) answers here.
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!
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?
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.
They were ok.  I had another group that came out that was much more thorough.  When I asked them to come out, they've always been good about that.  I make the appointments, all of them.  All of them, I make the appointments.  They were ok.  They cleaned the ducts.  But I've had others come out from Angie's List that have been much more thorough.  It's all on my terms.  Other people came out and they were much more thorough.  I would have given the other people an A.  They didn't take the ducts down.  The other people took the ducts down, they cleaned the vents and the whole bit.  They said that they could just do it like this and it works well.  I thought good, fine whatever.  It was positive that they came out on time.  They were very nice, they did their job, like I said, they weren't as thorough.  They cleaned my vents, but the other people that came out before, they took the vents out, they washed the vents, they cleaned every vent.  Whereas these people came in, they took the vents off and go I can suck all of his through these three vents with one hole.  And I'm sure they were right on that, but the other people did it differently.  I would not use them again because of that.  To make it better, clean out each and every vent and to clean the vents themselves.  The other people came out and they cleaned every vent that was exposed and they would go in and they cleaned out every vent.  Each one was cleaned out, not one vent will clean out three.  That kind of thing. Price was good.  I know you guys charge a fortune.  You take 40% of what they make.  I've learned that from a couple of them.  That's extreme.  They were all fair.  The prices were all fair.  But I felt bad that Angie's List took 40% of what they did because they did all the work and Angie's List took 40% of their profit, or their cost.  Now you're aware of it.  I've had three or four of them say that to me, and they said, well, we're not complaining because they keep us busy, but you know, that's not fair.  That's too much.  Everything's fair.  If I didn't like the price, I wouldn't buy it.  When the other guys came out, they did every single vent and they didn't.  I really don't like the fact of putting somebody down.  That's the way I am.  They did the work, they did what they felt they needed to do.  And it was different than what I've had in the past.  And I have allergies and all that stuff, so I really want all that junk out of there.  But, I wouldn't put them down.

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?
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.
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.

Most organizations concerned with duct cleaning, including EPA, NADCA, NAIMA and the Sheet Metal and Air Conditioning Contractors' National Association (SMACNA) do not currently recommend the routine use of sealants to encapsulate contaminants in any type of duct. Instances when the use of sealants to encapsulate the duct surfaces may be appropriate include the repair of damaged fiber glass insulation or when combating fire damage within ducts. Sealants should never be used on wet duct liner, to cover actively growing mold, or to cover debris in the ducts, and should only be applied after cleaning according to NADCA or other appropriate guidelines or standards.
A study done by U.S. Environmental Protection Agency researchers measured dust levels and HVAC system efficiency in test homes during a one-week period during the cooling season and found duct cleaning did not significantly improve dust levels or system performance. Based on that report and other independent research, the EPA’s official advisory on duct cleaning concludes:

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.

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.
A thorough visual inspection is the best way to verify the cleanliness of your heating and cooling system. Some service providers use remote photography to document conditions inside ducts. All portions of the system should be visibly clean; you should not be able to detect any debris with the naked eye. Show the Post-Cleaning Consumer Checklist to the service provider before the work begins. After completing the job, ask the service provider to show you each component of your system to verify that the job was performed satisfactorily.
