    Sight unseen there is no easy answer, but anything that is irritating to the respiratory tract isn't likely to be good for you.

    How much dust do you have?
    Is this something that just started or has it become worse over time?

    Everyone has dust and the source may be something as simple as age old dirt in the ductwork, your cleaning equipment and how clean you keep your home, pets, something your kid has done, hobbies or nearby activities such as farming, highway or building construction. If your home is new the likely culprit is construction dust.

    Have you or any of the previous owners done any remodeling or concrete work inside the house?

    Is there an attached garage where someone may have done bodywork or sandblasting or ?

    Do you have a central vacuum system? Check the power unit to make sure that it is sealed properly.

    Hobbies such as woodworking and crafts often generate a lot of dust. Laundry activities including dirty clothes from dusty jobs and powdered laundry soaps may also be the culprit. Other sources include personal hygiene products such as baby powder and byproducts from cooking and cleaning.

    Has there ever been a fire? Dry chemical extinguishers leave dust behind.

    Dryer lint is usually light grey in color, but to be safe check the vent to make sure that it hasn't been damaged or disconnected. If vented outside and easily accessible, turn the dryer on to high heat and put your hand in front of the vent opening or if out of reach watch to see if the vent door is opening properly. If very little or no air flow, then you probably need to have this vent cleaned or repaired and if its a gas dryer please don't wait as this same vent is used to remove combustion gases and deadly carbon monoxide. Also check the dryer door seal to see if it is soft and pliable or hard and brittle.

    Want to rule out the ductwork and can't see inside? Remove the vent covers and insert a small digital camera into the opening, then snap a few pics to see what's in there. If your camera won't fit try a flashlight and mirror.

    Knowledge is power and can save you a lot of grief!

    If you decide your ducts need cleaned, word of mouth is the the best way to find a reputable company. Check with several of the local heating and air companies and or fire/water/disaster restoration services and get a consensus of who they recommend and why! Most likely it will be one of the smaller companies you may never have heard of that relies on their own reputation rather than a ton of fancy certifications and a lot of expensive advertising.

    You should also take the time to do some research on the internet. Look at Heat Seal, Nikro, American Caddyvac and others to see what types of duct cleaning equipment they manufacture and sell, then compare their equipment to that used by the companies you call. While there are some scams running top quality equipment, most use a glorified shop vac or worse and at least you'll know the difference!

    Regardless of who you choose, get a guaranteed final price in writing before they start to work and be very wary of expensive add-on products and services such as soot sealing and sanitizing which are rarely needed if the system was thoroughly cleaned in the first place. Also watch their work and ask questions and if afterwards you feel that you were the victim of high pressure sales tactics or shoddy workmanship, contact your state's attorney general (online or by phone) and file a compliant!

    Explain to me how duct cleaning will fix the problem. What if the source is old nylon carpet breaking down by the sliding door from the sun? You know what happens then? Every time someone walks by the tips break off, get airborne and follows them around the house in their eddy currents. That stuff is so small that it will float around for a long time. I’ve seen an old white cotton bedspread be the culprit. It generated a white dusting though out the entire house every time the lady made up her bed in the morning. My suggestion is to find the source and eliminate it. It may end up that you have to take out all the carpet, install wood floors, wood blinds and buy all leather furniture. You might try changing the vacuum bag outside and cleaning the lint catcher from the dryer there too until you figure it out. Take one step at a time using the process of elimination.

    Sight unseen, it would be impossible for anyone here to accurately diagnose an indoor air quality issue, but there some important first steps that a homeowner can take starting with a slow walkthrough of their own home. Look for the obvious – a good spring cleaning may be all that is needed! Check for worn or dirty carpets, upholstery and fabrics. Clean the drapes and move the furniture. Vacuum below and behind. Get rid of the cobwebs and if you are allergic to dust – GET RID OF THE CLUTTER!

    If your basement is dirty, clean it - Dust from downstairs is going to come upstairs whether it be on your feet and clothes or through that missing section of duct that the cable guy tore down to run his wires through.

    Have an attic or whole house fan? Did you know that when operating these place your home under a negative pressure (vacuum) which in turn may draw in unwanted contaminants from outdoors such as smoke, dust and pollen?

    Have a fireplace or indoor woodburner. Be sure to shut off your attic or whole house fan as well as the one on your furnace and/or whole house air conditioning system before cleaning. Otherwise those fine particles released into the air will become part of the air stream being circulated throughout your home!

    Do your clothes take more than one cycle to dry? This often indicates a dirty dryer vent which in turn increases energy costs and can shorten the life of your dryer. If you have a gas dryer this same vent is used to exhaust toxic combustion gases safely outdoors including deadly carbon monoxide!

    If you have a forced air heating or cooling system – get in the habit of checking, changing or cleaning the filter per its manufacturer’s recommendations which is often monthly! If you have disposable filters, make sure that they fit properly and are of the right size and type for your system. When upgrading, choose carefully! Picking one that is too restrictive to air flow may lead to costly service calls and/or shorten the life of your system and it’s a safe bet that the clerk at the hardware store has no clue what will work in your system! Before upgrading, check with your hvac company to see if they are equipped to test your system and determine what will work best.

    Anything clean works better and the mechanical parts of your system are no exception. All are located on the supply side (filtered air side) of your air cleaner/filter and when dirty are a good indication that your duct work may be dirty as well. The most easily seen and accessible part is your system's blower and its cabinet and the hvac tech can easily show you their condition. Hidden are the primary heat exchanger (high efficiency systems will also have a secondary heat exchanger located directly above the blower) and/or the indoor coil for your heat pump or whole house air conditioner. When clean these critical parts keep your system operating efficiently which in turn reduces energy costs and the need for costly repairs. When clean they also increase system performance and prolongs the life of the system.

I don't run the air conditioner often yet as the temps here in Las Vegas have not hit uncomfortable proportion yet but I don't imagine it will be much longer.
    I am just as confused with this site as I am the powdery dust throughout my home. I don't know if I will be able to find your response. Please send to email address. It sounds just like my problem. mommagoose53@att.net This has been going on for a couple years. It forms a coating over the tv screens and reading glasses. Only during the winter that I know of. Have noticed when getting up in the morning and just a night light is on, you can see the air. It is all hazy. PLease.....I don't even know who to call or who to ask.

    Do you have an electronic air cleaner, edenpuire, electrostatic air filter? These remove the staining that makes dust dark. Do you have a humidifier? Has it been serviced?

    No I have none of these. I do have a small dehumidifier in the basement. This is a thick dust that is just hanging everywere. It will make a tv white overnight.

    for the amount of white dust your describing, wipe up a hand full and take it to get it analyzed. if your ac is down for a period of time and you still have dust than it doesn't sound like your AC. do you keep your windows open? do you have pets?

    get it analyzed

    Hard to determine without having the substance tested.

    If you did not see it before you had the new a/c installed then a good bet would be that the ducts were dirty and the installation disturbed the dirt inside.

    Other common causes are house dust, cooking, cleaning and personal hygiene products, pets, dirt generating hobbies, ash from fireplaces and woodstoves and older carpeting that is breaking down.

    May also be left over dirt and debris from remodeling or construction projects.

    Outside sources include your proximity to busy roads, construction sites, industry or farming, trash and leaf burning, etc.

    If you have ruled all of the above you may want to check for mold or if you have an older home that once had a coal stove then you may have asbestos inside the ducts and/or vent openings.
