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.
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!

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.
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.

I bought a Groupon and initially had to wait 5 weeks for them to make an appointment. I took the day off of work and they called 40 min prior to their scheduled time to let me know they had to reschedule as someone didn't show up for their shift that day. I then was scheduled 5 more weeks out and they called today to also reschedule that appointment, another 4 weeks out. I cannot speak of their work as their lack of professionalism has made me consult Groupon to get my money back however as I read the reviews this seems to be a theme with this company!
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.
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’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.

Duct cleaning generally refers to the cleaning of various heating and cooling system components of forced air systems, including the supply and return air ducts and registers, grilles and diffusers, heat exchangers heating and cooling coils, condensate drain pans (drip pans), fan motor and fan housing, and the air handling unit housing (See diagram).
