Metal is way better than flex duct or ductboard. It gets better airflow, holds up to critters and duct cleaners. I know of no hvac company here that cleans ductwork. (there probably is one somewhere) The mfg's of duct cleaning equipment keep trying to sell us hvac people on their benefits and profit potential but most all hvac people know that unless you have metal ductwork you are NOT doing the customer any favors.

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).
I turned on the AC when he was finished and immediately saw black fuzz balls the size of marbles come out of several of the registers. He said that was expected since everything was shaken up. So much for describing the service as cleaning. I paid him and sent him on his way. I cannot imagine that this type of service is worthwhile in anything but a new house. Apparently in old houses such as mine I can expect that using a whole house humidifier in the winter followed by a great AC can loosen the soot. Maybe this is to be expected for the first few weeks of summer each year. I now have lined the inside of the registers with cheesecloth to catch the fuzz. I’ll see if it stops after a couple of weeks.
EPA does not recommend that air ducts be cleaned except on an as-needed basis because of the continuing uncertainty about the benefits of duct cleaning under most circumstances. EPA does, however, recommend that if you have a fuel burning furnace, stove, or fireplace, they be inspected for proper functioning and serviced before each heating season to protect against carbon monoxide poisoning. Some research also suggests that cleaning dirty cooling coils, fans and heat exchangers can improve the efficiency of heating and cooling systems. However, little evidence exists to indicate that simply cleaning the duct system will increase your system's efficiency.
The next step was cleaning the cold air returns. He found a good spot to drill an 8” hole for his vacuum hose. The procedure matched the other air ducts except that when he finished at the two cold return registers he drilled several holes in the cold ducts in the basement and blasted air into them. Because of our houses age and the upgraded return system, I noticed that the main sheet metal return duct had no top but was just butted up against the ceiling in the basement. When he blasted air in, dust and crap shot out the edges along the ceiling. Once he finished that he removed the filter and “swept” out anything at the bottom of the return with his hand into the 8” hose.
I have lived in Calgary for quite some time now. When I first moved here I couldn’t stand the humidity levels. Its like a desert come winter. When I first moved into my new home, the house inspector insisted I have my furnace and ducts cleaned. I was very sceptical about duct cleaning to begin with. The company I hired came on time and were very respectable from the start. Before mentioning anything they asked me what my concerns were and what issues I was having. They were more concerned about addressing my issues then bringing anything non related up. I ended up going with this company and getting a humidifier installed a couple days later after the cleaning. Its been almost 4 years now that I have been here. The humidifier is working great and the difference is incredible. They took me around explained step by step what they were doing and the reasons they were doing it. With all those other companies out there, I am glad I found them at this site.

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.
Maybe I took him to literally but I am pretty sure cops wont show up to ensure that my duct gets replaced. He said it would be over 1000 dollars to replace the ductwork if that is the case. Now, I spoke to a friend who did 2 ductwork lines on his own in his attic and he said it was like 15 dollars for the plastic wirewound tubing to create new ducts. Should I cancel that appointment and just do the work on my own? I feel like I’m a chump or lazy for considering paying someone to do this work.
All of the products discussed above are registered solely for the purpose of sanitizing the smooth surfaces of unlined (bare) sheet metal ducts. No products are currently registered as biocides for use on fiber glass duct board or fiber glass lined ducts, so it is important to determine if sections of your system contain these materials before permitting the application of any biocide.
I paid $49 for a groupon. When the guy came today, he did an inspection first and said the ductwork first needed to be treated for mold; $348 for a spray that would last 8 months or $680 for an UV light purifier that would last 2 years. Also, the furnace needed to be cleaned for another $260. When I told him to just clean the ductwork, he said I would owe an additional $305 because the groupon was only good for 1 return and I had 2. I sent him packing with no services performed. Thankfully I am only out of $49! I will complain to groupon.
I just had my blower module replaced because my AC coil was frozen over. The underside of my coils had a thick mat of dust because I had never had it cleaned. I cleaned it myself by using a soft brush attachement on a shop vac. The inside of the blower appears to have a white/green growth, and I am sure the ductwork of my 30 year old house can’t be in good condition.
I noticed a lot of negative feedback, though unfortunately there are many dishonest companies out there. I currently work with a company that cleans duct work and we DO NOT use any scare tactics or up sell services or equipment. Once every 10years of course there are exceptions. We clean supply, returns, air handler, housing, motor, and fan. Though be discerning when qualifying anyone to work in your home. I would ask for REAL REFERENCES to contact.

I to had an odd layer of white'ish dust building up especially during seasonal periods when the HVAC ran a a lot. I carefully swept up the fine dust into a small pile and had it analyzed. Turns out it was very fine fiberglass powder dust. It turns out it is the insulation form the attic! (My attic has blown in insulation). Turns out if you (I) had small gaps around my HVAC registers in the ceiling whee the airs blows into the room. What occurred in my case was that the exiting air at that seam creates a vacuum effect at the grate vent cover and draws and then blows fine insulation dust from the attic into the house. Removing each register grate and sealing each tin outlet gap with calking between the dry wall ceiling and tin fixed the issue. A couple were so bad with bowed gaps I had to screw down the bowed tin to the attaching stud better. Checking the very same glass top desk that catches and shows any dust accumulation now shows only very small amounts of normal house dust build up over several weeks. A big, big improvement. You might have a look by simply removing a couple vent covers yourself.
Quality and price should come hand in hand, a too-good-to-be-true price for an efficient air duct cleaning will not give you the quality that you wanted. To make sure you are getting your money’s worth, check reviews of air duct cleaning companies, certifications from industry since this work requires continuous learning due to new techniques and research breakthrough from time to time. My mom is located in Arizona and they trust J&M Restoration air duct cleaning company, they have an A+ BBB rating, they used EPA approved sanitizing agents, their technicians are NADCA certified, and the company is certified by the Institute of Inspection, cleaning and Restoration. Make sure to shop around and get written estimates first.
I thought the price advertised at 129.95 for duct cleaning was great and called to clean our ducts. When they came in to do the the job I could not be home and my wife dealt with them. My wife ended up paying 954.00. They convinced my wife that there was 1.5 inches of mold built up on the Evaporators and coils. It is not the money, my wife could not go to the basement to witness the mold build up or the coil fouling. We have not cleaned our ducts for at least 10 years. The last price we paid for our duct cleaning was 150.00. My concern is that they told my wife not to turn on the heat for 2 hours due the strong chemicals they used to kill the mold. Are these chemicals approved as safe?
This is where i found where the major problem was for the dust problem in my home. I took down the sheet metal that was 16" wide down by taking the screws out that keep it attached and when i took it down i, could not beleive the amountbof dust that was up there, inhad to put on breathing nasks to actually scoop out all the cust with my hads and then i used my shop vac then bleached everything, i would say that i filled up a 5 gallon maybe more not counting all the dust that was attached to the side of the beams that was all wood , because the contractor did not actually build a 16" wide return all out of metal , butvinstead used the sheet metal plate as a short cut to make a suare box using my beams in my basement to make a suare box. I was told contractors do that often and i feel that should be outlawed because it caused my sinus and allery problems,nwhich almost caused me to die. so everyone should make sure their ductwork was made properly. Yes seal it . Cover all openings. So it was not the contractors fault that my vents still had dust, in them, he was afraid tomgetvon top of my pool table to try to get iside the short cut ductwork with the 16" wide sheet metal. To everyone, make sure you clean your vent system. And make sure you could see it visually like i did , neither i or the contractor had no clue the problem was right above my pool table because of the make shift ductwork. The contactor shoul have made a squrae duct like the rest instead of using my beams as a short cut. That could be whyba lot of people start to have major allergy problems and maybe even ashma.so coverall holes to prevent dust to be taken in and all bugs etc. then make sure you clean your ductwork as you see reasonable, they say every 5 years , but i say evry 2 to 3 years, but you can do it yoursely.. You need a good air hose and suction vacum like a shop vac, do a little research. I invented something a while back like 18 to 20 years ago , and now it is on the market to help homeowners such as ourselves with this dust problem. I cannont say anymore because i have to make sure that it was not my research and idea that solved my problem and for all the others that are using what i invented ..there was nothing on the patent search that i hired an invention company to do, back then. Once yor vents are cleaned properly younwill be very happybif you are an allery sufferer. Stop the children for throwing things into the ductwork and sweeping things into the ductwork, keeping your vent system is clean once youbclean it right the first time, just maintain it , you dhould keepmthe hvac system clean such as coils etc it truly helps,people vome into my condo and they cannont beleive how cold it igets and how my system works so well. it is because i have my whole duct system sealed outsid with the duct sealant and my coils i vleaned my self and take the time that the furnase fan is cleaned because that could have a lot of major dust attached to it, mine had a lot of caked on dust it was like hard dirt. Yxounwill save on allergy bills nasal sprays, i wish I could say more because incould say something to really keep your whole duct system clean for years once you do a first good cleaning of intake and return vents. until i email one of the major companies to see where they got my idea from. Intrulybhope it was not from the invention company i hired years ago who did the patent search for my idea. I becam
If you think duct cleaning might be a good idea for your home, but you are not sure, talk to a professional. The company that services your heating and cooling system may be a good source of advice. You may also want to contact professional duct cleaning service providers and ask them about the services they provide. Remember, they are trying to sell you a service, so ask questions and insist on complete and knowledgeable answers.
