I spent a lot of time reading all these posts and frankly I can’t believe the way some people think. 1. If there is dust and dirt of any kind in my HVAC system I want it out, the mentality that it can stay there and it’s fine is fulish as the system turns on and off microscopic particulates will move in and out of your living space and you will definitely breath them in. The air quality of your home or office will only be as clean as the system that produces it. We don’t not clean things simply because we can’t see them, it’s what we can’t see that can do the most harm. Dust will build up in a system fairly quickly and will get damp at times allowing mold to grow and mold releases spores without any movement as part of its defense meconisam so don’t tell me that when your system turns on it won’t blow the spores out into the living spaces of your home. A build up of dust will cause failures to your system over time, equipment that works harder to do its job will run hotter with more strain and this will lead to brake downs and until then the system will run less efficient then it should. The system was engineered to move a certain volume of air through a specific duct size, when that duct size starts to become narowed down with dust build up your system has to work harder to move that air this is why you will end up with a loss of efficiency and eventually breakdowns or failures. I have seen systems develop a significant amount of dust build up in as little as two years, just look at how fast the filter gets clogged up and it isn’t all that hard to believe. As for all the scams that are out there they hurt the industry because people can’t decipher between them and the legitimate companies, BBB is helpful. Recommendations from HVAC contractors will be a good resource and a good company will provide a written estimate with a complete brake down of what they are going to do and why, most of which is comen sence once they explain it to you, then if you spend about 5 minutes watching them once they are set up you can see they are doing what they said they would do and let’s get real would you do a job that should take approx 3 hours per system for $29/$39/59 or something close to that, if you think you are going to get a good job from a comp that has to make money at that price you shouldn’t be mad at anyone but your self for trying to get quality work at a scam price. If it’s done right it will be very beneficial and depending on the size of your system and where you are in the world it’s going to cost you approx $300 to $600 per system large and or older systems may cost even more. Remember a quality job isn’t wasting money but a lousy job is, even if it’s only $29. I’d rather spend $600 on a quality job then $29 on a lousy job!! Good luck..
My 48 yr old house (mine for the last 4 yrs) has considerable dust in the return plenum (fiber duct). I’m remodeling and recently re-sealed the return plenum AND the site-fabbed transition built when the new unit was installed, 2013. The return was leaky no doubt drawing musty, dusty air from the crawl space due to the Red-Neck fab & seal job! Pitiful craftsmanship! It took me 7 hours to fix the new transition piece. Anyway, the dust in the house is the same “color” as whats in the return duct and I’m getting way too much & too often in the house. I’ve also cleaned my coils, which were not that dirty.

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.
Be cautious with companies that offer “whole house air duct cleaning,” urges the NADCA. The company may be using unscrupulous tactics to upsell you once they get started. Before any work begins, always clarify in writing what the job entails and what the cost will be. To protect yourself against fraud, read customer reviews and verify that your HVAC cleaning service has applicable licenses and certifications.

But we don’t recommend hiring a duct cleaner to perform these tasks; too many don’t really know what they’re doing, according to the ratings of duct-cleaning outfits we have collected from local consumers. Consider hiring a top-notch heating and air-conditioning contractor to do this type of work, or pay them to do it during their next service visit.

Wow Really! Seems many of you just going for a low price or Groupon: THIS IS YOUR PROBLEM! You get what you pay for. Having the whole system cleaned including the furnace and it’s components, such as the coils will increase system efficiency. A camera/scope should be use before and after to show you the results.The needs to be done by certified professionals. It sure can’t hurt the indoor air quality.
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.
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.
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 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!
If no one in your household suffers from allergies or unexplained symptoms or illnesses and if, after a visual inspection of the inside of the ducts, you see no indication that your air ducts are contaminated with large deposits of dust or mold (no musty odor or visible mold growth), having your air ducts cleaned is probably unnecessary. It is normal for the return registers to get dusty as dust-laden air is pulled through the grate. This does not indicate that your air ducts are contaminated with heavy deposits of dust or debris; the registers can be easily vacuumed or removed and cleaned.
