Reduce Dust in Your Home and Save Money

There are many reasons to clean the air ducts in your home. When ducts are clean, the heating system lasts longer (because there is less dirt wearing out its components), we dust less often, and the air we breathe at home is cleaner. For those of us with allergies, this should be a welcome improvement.

Probably you don’t own a high-powered, truck-mounted vacuum system with 150 foot-hoses; perhaps you can't afford the cost of such service. But I am going to tell you how you can clean air ducts yourself. Sure, you won't be able to reach every nook and cranny, but you can still eliminate roughly 85% of the dust in your system without spending any more than the cost of your new furnace filter.

There are many different designs of duct systems, such as attic systems and underground systems, but the theory of cleaning these systems is the same. You may not be able to access all parts of these systems (for example, underground ducts), but you can make a difference in your air quality by cleaning the parts of the system that you can reach.

Things You Need to Clean Your Air Ducts

  1. Furnace Filter. You will definitely need a new furnace filter at the end of the job. Make sure you choose the right filter option for you.
  2. Vacuum. A household-type vacuum with a decent hose attached will work, but a heavier-duty "Shop Vac" unit is better, if available.
  3. Brush. Something closely resembling a toilet brush will work best, but a stiff-bristle paintbrush or something similar will do.
  4. Screwdriver or Hex Driver. Your registers are likely held in place by some kind of fasteners. You will need to use whatever tool fits the fasteners, usually a Phillips screwdriver or 1/4" hex driver.
  5. Paper Towels. Unless you want to do a lot of dusting and sweeping right after you clean your ducts, you will find these useful to cover some registers while you clean others.

Step-By-Step Duct Cleaning

1. Cover supply registers. Start by covering up your supply air registers (openings that supply heated air to the rooms) with paper towels. You do this to keep dislodged dust from drifting into the rooms as you work. Simply lift the register, wrap the paper towel over the top of it, and replace it.

2. Turn on fan. You want the fan running while you are cleaning, to move the dust along that you are going to loosen with your banging and brushing. Set the thermostat to "fan on," and shut off the "heat/cool" mode so that only the fan is running. If you don't have a fan-only option, you can run the heat, or you might take this opportunity to install a newer thermostat with this helpful option.

3. Check filter. Make sure your old furnace filter is in place, so that the dust you knock loose doesn't end up getting pulled into the fan motor.

4. Loosen dust in ducts. Knock loose any buildup of dust in the duct work. Simply take the handle of your brush and begin tapping on any accessible duct work you have in the basement. This will help break up any deposits of dampened dust that may have stuck to the insides of the duct.

5. Clean supply registers. Now you can start sweeping out the dust in your supply registers. With the vacuum running and the end of the hose near the register, lift the register. Use the hose to catch any dust that is being pushed out by the fan, and proceed to sweep as far into the register's piping as your hose can reach. Use your brush to scuff loose any built up dust in the register. As you go through the house sweeping out the supply registers, you can remove and dispose of the paper towels you've put in place.

6. Clean return air registers. Sweep out your return air registers. These will likely be fastened with a screw and require your tool to remove them. Again, brush and sweep as far back into the register piping or cavity as you can.

Return air registers are usually mounted to the wall.  They gather more dust and dirt than supply registers.

7. Shut off fan and furnace. Shut the fan off at the thermostat and the power off to the furnace via the service switch or breaker panel. Do not just shut off the thermostat, because that doesn't turn off the power to the unit.

8. Clean out blower compartment and return air boot. With the power off, you can remove the panels on the front of the furnace and access the blower compartment and the return air boot. Use your vacuum to sweep up the dust built up in the blower compartment and return air boot. This is where the great bulk of your dust will be. Since you’re in here, you should clean the furnace fan as well.

9. Replace furnace filter. Buying a better filter will definitely cut down on the dust in your home. But the better the filter, the more often you should change it; a dirty filter restricts the airflow to the fan, which results in the blower motor running hotter and reducing its lifespan. How often you should change your filter depends on your home, your pets, and your location.

Accessing Main Ducts

The areas you could not reach with the steps above are not likely to contain a lot of dust and dirt. However, if you are determined to clean every place you can, there are a couple more things you can do.

1. Remove end caps from rectangular duct work. If you have rectangular duct work, like in the picture below, you can remove the end caps to access the inside of the ducts. You can slide the "drives" down off the duct and pull the cap out of the "slips." So long as the duct is not butting up against the wall, you should be able to reach your vacuum hose in through the space uncovered by removing the cap, and sweep out any dust you find. You could even use a flashlight to look inside the duct for dirty areas.

The vertical piece of metal on the right is called a drive. It is folded over on the top and bottom of the duct to hold it in place. With a pair of pliers, you can unfold it and pull the drive down off the duct on both sides to detach the two pieces.

2. Clean inside basement registers. Often duct work will include registers installed throughout the system to distribute air to the basement. If you remove these registers, you'll gain even further access to the main trunk line.

Congratulations!

If you do what you can of the items above, you will have made a significant dent in the dust in your environment, and you will have done the best you can, short of calling a professional air duct cleaning company.

      Pastor B - First, thank you for the kind words! The answer to the first 2 questions in a nutshell is yes. Running the fan however by itself is probably the better idea to dry the system a bit. That said, it isn't a solution, just helps a bit. I would attempt to find the root of the problem and take care of that to end the issue. Adding things like air cleaner and UV light to the system can help long term with some of this but having the a/c coil cleaned and checked (the indoor evaporator coil) is a good start if you've not had that done before. If the smell is coming from the crawlspace and getting pulled into the air stream is the issue then sealing the ductwork with a mastic may also be a good measure and is something you can do yourself with a bucket of mastic, a paint brush, pair of rubber gloves and long sleeves....you don't want to get it tangled up in your arm hair and such. It can be a difficult task to get out. :-) I hope this helps and thank you for reading!

      First of all your website is great and very informative! Thanks for a willingness to help!!!

      My question is a three-parter, which results from as soon as I turn on the AC, "IMMEDIATELY" there is the smell of damp air:

      1) Can crawlspace air dampness get inside the heat exchange causing dampness in my duct work ?

      2) Can an extremely dirty evaporator coil cause dampness and moisture in the duct work or do I just need to clean the evaporator coil and the return duct as well?

      3) If I turn on the heat, will it dry out the moisture that's in the duct work?

      I await and look forward to your recommendations, and again thanks. May God bless you for helping people with your gift in this profession!

      Deb - I've never been asked about tear gassing nor do I have any experience with it. I would think not. I don't know that a standard professional duct cleaning would do it either. Maybe call a disaster restoration company and see what they recommend. They handle drug lab clean ups and things of that nature so they could probably offer better advice. Thanks for reading.

      Well the idea is to create even airflow but quiet honestly, it's not often achieved. Not even in my home. You can have a company come and balance the system but they may find it has something to do with the design or have to add a booster fan or some sort of control system to make it fully balanced. It is something that could cost $100 or $1000. Thanks for reading and commenting.

      My floor register in my room doesn't allow much air flow. I've tried reaching down as far as I could with my long arms but can only get so much. My understanding is all ducks/floor registers are connected for even air flow in our basement. Everyone else's gets a lot of cold air blowing in theres. How can I get my registers air flow to work better

      Jill - Not all HVAC companies clean duct. There are actually businesses who specifically do just that. I'm not sure who you spoke to but that is something to consider. There are also certain duct systems that perhaps only a few companies would be equipped to handle.

      My first thought is that you have underground duct work. If so, there are various ways to address that but I'm not real familiar with them. If you don't then I'm still not sure what that could be. If you're in heating season, some furnaces will smell bad because the heat exchanger is bad and if so, you need to consider a new system if you're not under warranty. Note: Many heat exchangers have rather long warranties. 20 years...maybe lifetime.

      I would definitely need more info than this to help but will say first thing is to check your filter. Also, when is the last time the coils indoor and outdoor were cleaned? If the unit is running proper and you're not getting air, these are the usual suspects.

      Colleen - I assume you have underground ducting then and you would need to have them cleared and sealed which will likely require a fair amount of money and a professional. If they aren't underground and you're experiencing this then it sounds like your ducts are in need of insulating because they are in an unconditioned space and the inner and outer temps are creating condensation. Thank you for reading.

      Violet Shrop - Thank you and no. You don't want the power off while cleaning registers...you want the fan running. Now once you get to the furnace itself, at the end and you're ready to change the filter and wrap up...yes. Turn off the power.

      This is really well written & helpful. Just to make sure: so to clean your return register, you don't need to shut the power off? I wouldn't think so either, mine looks like yours, just a space under the hvac cabinet, no electric element seen. Thanks.

      Tyler - Yes. If the breaker to the furnace is off, you should be safe under normal circumstances. A simple voltage detector is always nice to have though to be sure. You just touch it to anything and if there is voltage, it will blink and/or beep. Only costs like $20 and is useful for many things. Thanks for reading.

      Christine - I think you're misunderstanding. I'm recommending you cover the supply registers, not the return and only temporarily, not forever. It would take a lot more than a paper towel over the supply registers for a few minutes to burn up a motor. Especially on the supply side. If it were return air, I'd say you're right but even then, it would take a lot more than a paper towel and few minutes to cause any sort of damage to the motor.

      We bought an older mobile home over a year ago. I bought a wet dry vac and it didn't have enough suction power to vacuum the floor duct. The return air is disconnected. I run window a.c. units and have just floor heat. There are blockages in the duct. So, is a shop vac better than wet/dry vac? I need heat desperately before winter arrives.

This rehab house has been sitting for 9 yrs and only God knows what's been lurking and swirling around for the 2+yrs since we installed the furnace. Now with 2 cats everything gets covered in dust especially in the summer with no central air, only high-powered floor fans. I bake cakes and have to turn them all off to keep the dust, lint, cat hair etc from landing in them! Eeek...and when the sun shines through the window the dust becomes even more visible! Dust, dust, dust...I can't take it any more and will be so happy when we're done with this DIY project! Update to follow! Thank you so much!!!! Mmmwah

      MarkE 2 years ago

      I would like to add that a lot of the dust is from your home and mostly found in your return vents and return ducting because as it pulls the air into the ducting from your house, along with the dust and moisture, some of it will gravitate towards the bottom of the ducting due to

      1) gravity

      2) moisture condensing

      3) static electricity

      Your supply vents ought to be relatively clean in comparison due to the fact that there is an air filter upstream from the supply vents preventing any dust , usually, from going any further than the filter. However there will be some albeit a lot less in any event.

      Banging on the outside of your vents may release some dust but opening up the vents at their ends if possible will allow you to vacuum a heck of a lot more dust.

      I am replacing as many joist liners as possible, because it is relatively cheap and gets rid of any rust, mold, bacteria, and of course dust that you may or may not see.

      Good luck in your ventures, may the wind always be at your back!

      Well, if it's just a piece, I'd throw it away. It's likely a scrap piece that's been in there longer than you may have realized and in your cleaning, worked it's way to visibility. Unfortunately, much debris found in duct is from construction and people using the duct as a dustpan. If you don't see any parts missing or holes in the ducting, then just toss it and know that they're that much cleaner.

First off, if you really read the article, I clearly state this is a pretty good way to go if you don't have the money for professionals. I'm guessing you're a duct cleaner and don't want me showing people a nice alternative that will save them money and improve their air quality far more than doing nothing. My articles are not aimed to help or hurt anyone's business...only to help people who can't afford such services to do the best they can to help themselves enjoy these luxuries when it's within their ability to do so. I stand by every word in this article. With over 20 years in HVAC from loading trucks to currently running large commercial projects and everything in between, I think the professionals are already on it.

Unfortunately, in a new home, the drywall and sawdust often gets into and is swept into the heat vents. Get it now and it can help a lot.

      Awesome - thank you so much. You're right - I don't have a high-powered vacuum with a super long cord, so your instructions are perfect.

      Congrats on the hub of the day!

      Boy, I wish I had read this when I was still living in my old apartment- that ventilation duct needed some serious cleaning and I didn't know that it was so easy to do!

      There are many things that people can do themselves in regards to HVAC when given the needed information. I am glad you find this useful. I have and will continue to publish hubs that not only show people things about HVAC they can do themselves but will also save very significant amounts of money. HVAC is an expensive service so anything you can learn to do yourself will save a minimum of $125 as this is the common base rate of a licensed service trip.

      Great hub! I didn't know this was something I could do myself. I live in a pretty windy area and dust is a major cleaning issue so I'm pretty sure the ducts are going to need this!

      Very useful. You're right about the cost. we paid close to a thousand for a professional cleaning last time. I forwarded your hub to my husband who is responsible for those type of work. Hopefully, this will save us some money. ;) Thanks for sharing!

      @ poowool5 - It actually was not at my home but yes, it was real. You can't fake that. (He typically is clean though...just out of the country for a few months and needs his ducts cleaned!)

      @ Marcy and all others - First, thank you very much for the positive feedback.

      Like I'd mentioned in the hub, this isn't a professional duct cleaning. One might pay $300 - $700 for a professional cleaning. For someone who doesn't have that kind of money for this type of service, they can do it themselves and achieve nearly 85% of the success. Knowing that people don't have the equipment or ability to disconnect the entire duct system as a service might do, this is a great alternative. As for the fan, since we don't have a truck mount unit that pulls the CFM as they clean, you need something to move the loose dust down to the filter. Since you banged on the duct, the dust would just sit there and you wouldn't be able to get to it. This is why you wrap the registers with the paper towel though most of the dust is being pulled back to the blower as opposed to push out of the vent.

      You'd be surprised as to how much of the dust collects at the blower and just inside the register itself. The rest of the system is likely quite clean and with our knocking, even cleaner now. One could feel free to take apart as much of their duct as they are comfortable with but for the time this could take, I'm not sure it would be worth it unless you are well versed in how to do it efficiently.

      Also, buy better and replace more often the filters. You can buy a lot of good filters for $500. (Multiplied by however many times you pay to clean your ducts.)

      I hope this further explains the situation. HVAC is very technical, requires a wide variety of uncommon tools and I try to keep it easy to understand to the average homeowner. Beyond that, there could be licensing required by law in certain cases.

      Clear and concise. Now I know how to clean the air-con, not that we need it over here in the UK.

      Voted up and shared for my friends that do though.

      I have wondered if it was okay to tackle cleaning ducts yourself. I had them done professionally years ago, in a different house, and it was quite a job - but they had a rotor rooter sort of thing that went all through the duct work.

      I'm curious as to why you would leave the fan running while you do this? Wouldn't that increase the chance of the dust getting into the house?

      Thanks for your hub! Voted up, useful and interesting!

      Oh dear, another thing to add to my to-do list! But at least I know how to do it now, Crea8tor, thanks to this very clear and well-explained hub. Nice job!

      Love your first pic too (was your home really that dusty, or did you have to "fake" the dust??!)

      Cre8tor, this comes at the perfect time for me: the dust in my house has been increasing (and I hate dusting!) and I have been looking to the ads for duct cleaning services with new interest. Thank you for this clear and easy directions on how to do it, I foresee duct cleaning being added to my spring cleaning list! :)
