I have been a plumbing/gas/hvac tech for 19 years, before that I installed ductwork in commercial buildings and office towers. As the article states, unless you have undergone some type of extensive reno, or ducts have become contaminated, paying for cleaning is pointless. Its one thing if you have a 30 year old home that has never had a duct cleaning and you can actually see mounds of dust built up , especially in the return side, then go for it. Keep in mind that most duct cleaning companies will only get 80% of the dust , or less at best. Keep in mind that most of the dust in your home is lint from clothes and linens, and skin cells from you and your pets and is constantly being generated. Dust that builds up in ductwork , generally stays in the ductwork. The power of suggestion, scare tactics, up sell!!!
Free cooling systems can have very high efficiencies, and are sometimes combined with seasonal thermal energy storage so that the cold of winter can be used for summer air conditioning. Common storage mediums are deep aquifers or a natural underground rock mass accessed via a cluster of small-diameter, heat-exchanger-equipped boreholes. Some systems with small storages are hybrids, using free cooling early in the cooling season, and later employing a heat pump to chill the circulation coming from the storage. The heat pump is added-in because the storage acts as a heat sink when the system is in cooling (as opposed to charging) mode, causing the temperature to gradually increase during the cooling season.

In addition, the black dust was found in most of the heat registers. He could rub it off on his fingers but did nothing but spray compressed air on it which didn’t make it disappear since it wasn’t loose. Also, in the register in the basement he described the black dust as being oily. The reality of that situation is that I had the AC on until the morning of the service and minutes after he snaked the hoses in my back door it started raining. The basement register had condensation from the humidity all over it. It was not oily but wet. He asked for an old towel and wiped it out. Never saw anything so black – because I never had to clean soot. That is what I have in my ducts. Soot from years of the old coal furnace.
in response to this reply " should your ducts be cleaned", i have to politely correct the person who answered this. you are not using common sense. first, most of the country uses metal duct work, so for you to say what you did, is wrong. second, the duct system in a house is a circulatory system. that means it draws air into the furnace, it gets filtered, and then it is blown out into the house to heat or cool. So, obviously that air is being brought into the house from somewhere right? Yes, its coming from the outside where there are many allergens and dust particles . For you to says that about whether a duct system is sealed or not, makes no difference. The air is coming from somewhere right? It has to originate from somewhere right? Just look on top of your cieling fan. If there is a bunch of dust up there, then there is obviously a bunch in your ducts. And the duct air is being circulated every day, and every hour through your house. Its simple, dust collects everywhere in your house. Imagine if you never dusted your shelves, or tv? There would be a ton of dust after a while. Well, now think about the air in the duct system. Of course theres gonna be a ton of dust in there. For you to say that it is not benififcial to clean the ducts, is plain ignorant. 90% of the air we breathe is in our household. Wouldnt you want that air to be as dust and allergen free? I could go on for hours about the benifits of duct cleaning, but i just wanted to make a quick point that the person whose says it is not benificial to clean them, is not using common sense. Not to mention, giving the people who clean ducts for a living, a bad name. Use your head .

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.
Yes everyone should get all their ductwork cleaned, because it does help, incame down with major allergies and had serval operations on my sinues because of this problem of air quality and dust, plus i almost died from one of the operations, i was suffering so much. Yes you can seal your duct system by buyind duct seal t instead of tape to tape all the corners of the vent system, tape wears out and gets brittle, the sealant you can buy at home depot, and you just brush it all over the connections of your ductwork, it comes in a container and it is like a thick paste and dries making a good seal for your ductwork.

So HVAC sent Tony Diaz to my house. I was at work so he was subjected to the most excruciatingly exacting woman on the planet (my wife). Tony impressed her with his friendliness, professionalism and the obvious jouneyman-level knowledge of his craft. He found literally --burnt-out-- parts in our system and replaced them. It cost us a bit but I know enough about the parts to see there was no gouging on the parts and a fair rate for the labor. It wasn't cheap but it was fair and worth every dime.
#3 The ONLY time Duct cleaning is needed is when the home had a fire, Bad roof leak on to FIBERGLASS ductwork or house sat vacant for many years with out the air running. And its better to replace than to do “abrasive” duct cleaning. If the duct cleaning has a rotating brush it will remove part of the glue that is holding the Fiberglass in the ducts together, PERIOD no matter how much the say it don’t because the brush is soft.
You might also want to check your home for thermal insulation if you live in extreme heat or freezing temperatures. Insulation keeps the heat and cool air in your home, which can lead to a lower electric bill. If the heated or cool air leaks out, your system turns on more often. There are various types of insulation that you can install in your home and a home energy auditor can point out the best places for it in your house.
Despite Bergendahl's experience, Vinick says NADCA's certification standards have improved the situation. "A lot of [service companies] weren't going about it the correct way," he says. “We have an anti-fraud task force, and we’ve gone after some fraudulent duct cleaners with the help of state attorneys general.” He suggests that in addition to NADCA membership, homeowners make sure their cleaners are an established business, have appropriate insurance and are registered to do business in their state and locality.
In some older homes, there was a grey Mylar flexible duct. After years of use, it started to decompose. A duct cleaning company can come out and find why your air is so dirty and why your building doesn’t heat or cool like it used to. This is a savings on your part. You could also be sucking in Hot, dirty attic air. However, sometimes when a duct cleaning company comes out to clean it, the old duct can be destroyed and have to be replaced. Someone with little experience can replace this ductwork but if it isn’t done right it can ruin a lot of things and cost a lot in repairs.
Reinstall the access panel and disconnect block. Turn on the circuit breaker and furnace switch. Then set the thermostat to a lower temperature and wait for the AC to start (see “Be Patient at Startup,” below). The compressor should run and the condenser fan should spin. If the compressor starts but the fan doesn't, the fan motor is most likely shot. Shut off the power and remove the screws around the condenser cover. Lift the cover and remove the fan blade and motor (Photo 7). Reinstall the blade and secure the cover. Then repower the unit and see if the fan starts. If it doesn't, you've given it your best shot—it's time to call a pro.
I always get a laugh at anyone claiming to be in the business for any length of time that doesnt understand the importance of cleaning out a ventilation system. Not only for better indoor air quality but for maintaining your heating equipment. I guess it makes more sense to some people that the furnace will just run better with a ton of dust and debris and maybe this wont be a big cause of sytem breakdown and malfunction. I mean really? Maybe this guy got a bad company and or cleaning and is a little jaded but to advise cleaning your grills , which does nothing, and replacing a filter....come on guy.
Do you live in a historic home and want to tie your new system in to work with existing features? The price will go up to do the job right. All of these things add up to slow down the HVAC company, which takes more time, which costs more money for labor and parts. This is especially true if they are a legitimate company which is licensed, bonded and insured. Simply put, this is the “X-Factor” in your HVAC installation cost. Again, you could get people to do it for cheaper…but you won’t be happy with the results, I promise.

A little simple math can help determine the size system you need. A rule of thumb is 20 BTUs per square foot. So, a 500 square foot room would need 10,000 BTUs to cool or warm it efficiently. This assumes that you live in a temperate region and have adequate insulation with no energy loss. In the real world, all units have some degree of energy loss. This is reflected in an HVAC system's SEER rating for cooling and AFUE rating for heating.
I know it has to have a new concentric venting system installed, I believe it needs new plenums ( mine are rusty but both of these require extra work , so someHVAC persons are saying I do not need either!! RED FLAG THERE. Also, it will need a new drain using PVCP ?? Piping run maybe two, depending on where my evep coil drain is conected (here in TN they use to run them in with the septic lines, now they cannot be run through that way), Lastly I am not where or what these things do beides hold water but I was told It needs a filter rack and new filter base safety pan. THATSSS it that is all I know about this stuff aside from the fact that nothing up there is to code thus far LOL. !!
An air conditioning system's SEER is especially important if you live in a climate that changes temperature dramatically. The SEER is determined by the cooling output during the winter divided by its electric input during the winter. The higher the rating, the more efficient it will be. In January of 2006, the U.S. put standards in place for cooling units which are still in effect today. They must have a minimum SEER of 13. So, if you live in a home with a system installed before the new standards went into effect, consider having it replaced. SEER 13 units increase home efficiency by 30 percent.
Refrigerant Metering Device -- Every HVAC system has one of these, and heat pumps have two. They regulate the amount of refrigerant going through your air-conditioner. If it fails, either too much or too little refrigerant will course along the lines and either not perform well or will overwhelm the compressor and cause it to fail. A total failure of this component will result in a complete loss of operation.
In reading through all this about duct cleaning, THE ONE preventative measure people need to realize is that a poorly installed HVAC system that is not sealed and air tight to ensure that ALL indoor air passes through a GOOD air filtration system IS THE best means of ensuring your ducts remain clean. Duct cleaning does not now and will NEVER improve an HVAC systems efficiency. Proper maintenance and installation are the key just as improper installation practices allow for dust infiltration into the duct system. I am a state licensed contractor in Texas, and unless people have their hvac system sealed and/or properly installed, duct cleaning is an absolute waste of money. My duct system is 12 years old as is as clean today as the day I installed the system with ductwork. SO before ANYONE jumps on the bandwagon of duct cleaning, get with your hvac professional FIRST.
All these pro duct cleaners answer with "it's common sense, everything operates better when cleaner" etc. But your explanation is correct. Especially so with flex tube ducting where dust gets "stuck" between the lowest valleys (between wire coil supports) where air flow is drastically reduced -- which is more than 50 pct of the entire interior surface area of the flex ducting. That sounds like a bad thing but also has a good effect of trapping dust from escaping.
On the other hand, if a service provider fails to follow proper duct cleaning procedures, duct cleaning can cause indoor air problems. For example, an inadequate vacuum collection system can release more dust, dirt and other contaminants than if you had left the ducts alone. A careless or inadequately trained service provider can damage your ducts or heating and cooling system, possibly increasing your heating and air conditioning costs or forcing you to undertake difficult and costly repairs or replacements.

HVAC is an important part of residential structures such as single family homes, apartment buildings, hotels and senior living facilities, medium to large industrial and office buildings such as skyscrapers and hospitals, vehicles such as cars, trains, airplanes, ships and submarines, and in marine environments, where safe and healthy building conditions are regulated with respect to temperature and humidity, using fresh air from outdoors.

Prices for central-air HVAC systems will vary. The national average to hire an HVAC specialist is $2,920-$3,670 but can run as high as $5,000 or even $12,000 depending on the capacity you need and other factors. Installing central air conditioning requires an entire system that works together to draw hot air out of your home. The system includes an outdoor unit, which houses the condenser and compressor, and the evaporator coils. If you don’t have an existing duct system, ductwork will need to be installed, which will affect labor and material costs. Leaking or damaged ducts will also need to be replaced.

A Full Installation is the most common type of HVAC installation for a reputable contractor. The ductwork adds two days of labor and about $2,000 to $3,000 to the price, but realize that this is a very important part of your HVAC system. Although it might sound like a good idea to reduce HVAC installation cost and get a quick change-out, realize that there is dirt and debris collecting in your ducts, and the ducts themselves develop holes and full breaks over the lifetime of your unit, all of which may be hidden from sight by insulation. Remember, many contractors will push a quick change-out on you because it is easy and good money for them – you need to be involved and ask questions.
HELP is am drowing in LENT . It has been noticed in the master bedroom there is lent all over the furniture and the floors. I have dark brown/black furniture and same for the wooden floors. There are wods of lent every day. My furniture covered in lent. The rest of the house is fine just the tipical dust. I am sure my lungs are also full of lent. I looks like if my dryer vent was in my bedroom. Please help
One of the best ways to know if your ducts or vents need to be cleaned is to just check them. Your eyes will be able to check for indications of mold, dust or pollen buildup. You might also be able to smell the presence of mold, which would be a clear indicator. Ductwork will have some buildup of dust, since the return registrars pull air back in. However, this doesn't mean your ducts have too much debris, and you can easily clean them with a duster or vacuum.
My Carrier furnace occasionally (one-two times a day) does not start. It shows error code 15 ("BLOWER MOTOR LOCKOUT -This status code indicates the blower failed to reach 250 RPM or the blower failed to communicate to the variable speed furnace control within 30 seconds after being turned ON in two successive heating cycles."). However, when I turn off and on the furnace power switch it starts and runs fine for a while. Sometimes it runs fine all day, but does not start only once in the evening or in the night. It is 13 years old I was thinking to replace whole thing if repair cost is too high. But I am not ready to pay $10,000. 
An energy recovery ventilator: This component helps improve the air inside your home by swapping it out with fresh air from the outside. During the winter months when houses are closed up to keep out the cold, the air inside becomes a handy way for colds and flu to infect an entire family. By circulating outside air inside, the health of your family will have a better chance.
I can’t believe I got ripped off by this Air Duct Cleaners. I called them for this $63 coupon per furnace unlimited vents then when they came after he checked it all I hear is I have molds and leak all is worth $499, $799, $899 per furnace but I told him to just clean the duct and patch the single leak per furnace worth $38 each. Still eanding $899 total. All the work he done is in less than an hour he didnt even go to each vent to clean it. All he did is to path the air leak on that entry pipe to the furnace and open the main venting system, vacuum it, and wash the floor of the vent with a solution. Overall time is about 20 mins talking with me discussing all the option which thinking they made me think I don’t really have an option and 40 mins wash and vacuum he took pictures of before and after of only one furnace. He gave me a receipt without the details on what he has done in the house just the name and price. I think we may need a strict law to punish and control all this companies who do this so other company who do good will despise them.
The HVAC industry is a worldwide enterprise, with roles including operation and maintenance, system design and construction, equipment manufacturing and sales, and in education and research. The HVAC industry was historically regulated by the manufacturers of HVAC equipment, but regulating and standards organizations such as HARDI, ASHRAE, SMACNA, ACCA, Uniform Mechanical Code, International Mechanical Code, and AMCA have been established to support the industry and encourage high standards and achievement.
I own an HVAC company. Dirt in your ducts stays there and hurts no one. It is like dirt on the ground outside. This industry was infiltrated by a bunch of money grubbing low lifes years ago. As a credible company, we do not clean air ducts. Some who were credible probably signed on not knowing what else to do or to try to make a buck another way. These companies, because they also do HVAC work not only rip off private homeowners, they are ripping off legitimate HVAC company's customers and the integrity of what can and should as a rule be a great service industry. Some probably have gotten into this to simply offer what competitors who were ripping off their customers were offering. Anyone cleaning ducts is in my opinion raising a big red flag that they cannot and should not be trusted. Political pressure from NADCA, advertising dollars, manufacturers and marketers of duct cleaning equipment, and intense competition for the customers is the only reason the government and adverstising companies have not run them out of business and that this cancer perpetuates itself.
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.

I live in a 1950's ranch house in the South. The prior owners were smokers. Based on recommendations from one of the local conservation organizations, I decided to have a home energy audit done. As part of their findings, they recommended additional insulation in the attic and duct cleaning and sealing. This turned out to be a very problematic process. In terms of the ducts, it was necessary to remove the metal grates. However, these grates had been painted over many times and shoe molding covered the bottom of the grates. The vendor was not able to remove the grates without damaging them in the process. Because these grates dated back to the 1950's, it was difficult to find appropriate replacements. The ones I finally discovered were correct except they were 1/4" wider. This meant that the shoe molding had to be carved out. The duct cleaner could not provide any assistance with this problem. It took me a month of long evenings replacing the vent covers myself, carefully chiseling out the shoe molding and repainting. In terms of the extra installation in the attic, the same vendor used blow in insulation. Unfortunately, they did not recognize that the 13 floodlights whose mounting extended into the attic were not designed to be buried under insulation. The problem manifested itself in terms of expensive flood light bulbs failing continually. So, I had to have all of the light housings replaced. Yet another unexpected expense. Despite the expense, pain and suffering, I cannot report any improvement in my heating costs or the "quality" of the air. To be fair, I do not have any allergies and did not undertake this for air quality improvements but rather heating efficiency improvements.
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.

yes get a good company and pay the price, I found so much dust and dirt and wood and paint chips and bugs and even bottle caps in my ductwork. I hired a major plumbing company who cleaned ductwork and i will say they did an excellent job cleaning my vent. they did miss one point in my ductwork because i still started to see dust all over my furniture and i realized that my retunduct work that was connected with a piece of sheet metal beam which was 16" across , the contractor that built my condo used a 16" wide sheet of sheet metal to connect the vent system to my return for the air to return back into my condo. The contractor should have built a 8" x16" square duct by 6 feet long to connect my intake to my return instead of using a sheet of sheet metal 16" wide by using two 3' sections by 16 inches wide. That was a shor cut which caused a major problem fir me.

Be careful of dishonest HVAC contractors. There’s no magical formula to see if an HVAC contractor is scamming you, unfortunately, but remember that they typically do this in one of two ways: first, they are charging grossly low prices (far below everyone else), or second, they aren’t including what everyone else is. In the first situation, they will charge you change fees, other hidden fees, or they stole the equipment and are passing themselves off as legitimate contractors (very common in California these days). In the second situation, they are charging you a very fair price, but aren’t including what the other contractors are (i.e. charging $10,500 for the installation which is fair, but not including the ductwork which is a scam unless there is some other, complex stuff going on there).
While you consider having your air ducts cleaned, it is a good idea to take a look at your dryer vent. If your dryer vent is clogged, you could be losing energy efficiency. Worse yet, you could be increasing the risk of a house fire. Having your dryer vent professionally cared for costs about $130 on average, and could save you a bit of money and a lot of headaches in the future. For more information on the benefits and cost of having your dryer vent cleaned, take a look at our comprehensive cost guide.
If your non metal ductwork is that dirty you should just have it replaced AND sealed. Also most duct systems are not very well designed. Look for proper sizing and do not go cheap with one or two intakes (return grills) You need them through-out the house. Here in Austin the duct cleaners are carpet cleaners and chimney swifts. (this is who the duct cleaning equipment mfgs call on when the hvac people do not get on board. They DO clean other types of ductwork and we (the hvac guys) have to fix them. I am not aware of any of these non hvac guys cleaning and servicing the actual equipment. Here in Texas it is against the law for them to do so. Treat the entire house as a system, not just the ductwork and /or hvac equipment. Home performance really does work to increase comfort and air quality while reducing operating costs.

I purchased one of those Amazon air duct cleaning coupons for 49.99. When the company showed up, they removed the vent closest to the air intake and immediately told me I needed $1800.00 for all new duct work. They said they could not clean the system until new duct work was installed. I thanked them and said I would give them a call. The only call I made was to Amazon to get a refund. I know I didn’t need new duct work. Be careful to not fall for unscrupulous salesmen and their pitches and scare tactics.
Clean the condenser fan blades before the start of the cooling season. Brush any dust or debris off gently and then uncover the condenser coils, gently cleaning the dirty side. Then wrap the motor and other electrical components in plastic bags and gently spray from the inside with a hose. Now check the base pan under the unit and clear it out of any debris that has gathered.
Fuses -- Anyone who has worked with electrical systems knows all about fuses and how they fail. They can burn out over time, may just be loose, or can blow out during an electrical storm or due to overload from another failed component. Of course, that's what they're supposed to do; they stop surges from going through and damaging the rest of the system. When a fuse fails, whatever system it was protecting will stop working.
When these aren't properly maintained and sanitized, they can build up dust, pollen, and even mold. This means when the air conditioner or heater turns on, the spores are released into the air for you to inhale. While some are less harmful, people who have allergies or sensitivity to certain spores will react negatively. Plus, mold is dangerous for anyone to ingest and should be avoided by regular maintenance.

Indoor Fan Motor -- Indoor fans circulate the air from your house and through the system. Age and dust buildup are the two biggest contributing factors to their failure. When they are starting to fail they will often make noise. Failure of the fan will result in no heating or cooling, and if it is not repaired soon, it can cause other components to fail.
A little simple math can help determine the size system you need. A rule of thumb is 20 BTUs per square foot. So, a 500 square foot room would need 10,000 BTUs to cool or warm it efficiently. This assumes that you live in a temperate region and have adequate insulation with no energy loss. In the real world, all units have some degree of energy loss. This is reflected in an HVAC system's SEER rating for cooling and AFUE rating for heating.
Furnace cleaners are mostly young men, I know this, I have been one for 15 years or so……so heres the truth, if there are any allergies, children, older people with health issues, we are GOING to make money. do not tell the company you have hired about any health complication. they are salesmen. and they don’t care about you. or your money. make sure they do a good job, then kick them out. you don’t need all the bells and whistles they wanna sell you. any idiot can clean duct work, like I said, I am one of them. I am very good at it, but I don’t have the back bone to sell a widowed old lady a humidifier that she doesn’t need for 500 bucks, overall, if you think you need this service done, which you probably don’t, get it done, do not spend anything over 300$ and do not do it again for at least ten years.
I had my ducts somewhat cleaned December 22, 2014. The hose of the machine the technitian used did not fit in some of my vents, therefore, he did not clean them. But I still paid $428.00 for the service. I will be calling the company on Monday, and kindly ask them to come back and clean the ducts they did not as they did not fullfill their part of the service.

Vinick calls air duct cleaning an essential part of home maintenance, akin to mopping and vacuuming. "It’s like changing the oil in your car,” he says. “If you don’t change the oil, you’re going to have a problem. When your components are loaded up with debris, the system has to work harder. When you remove that debris, you get energy consumption savings.”
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.
We moved to a house built in 1965 from a 1915 house with a dirt basement. Against what I anticipated, the 1965 house was much dustier. It was like felt on top of everything. I cleaned and cleaned and it did become less dusty over time. We then found out a cat lady with over 2 dozen cats lived in the house in the past. We then had to get our furnace replaced and I was able to look down some of the duct work, the dirt and debris was 3-5 inches deep. Additionally, the basement ducts were entirely plugged with debris including dirt, seeds, ants, toys, etc. I had already removed what I could from those. We had our ducts cleaned last year, and the dust in the house is greatly reduced. Also have lost the runny nose I got after moving here. There are duct cleaning con artists out there, but ours did a good job.

With the split system, the evaporator coil is connected to a remote condenser unit using refrigerant piping between an indoor and outdoor unit instead of ducting air directly from the outdoor unit. Indoor units with directional vents mount onto walls, suspended from ceilings, or fit into the ceiling. Other indoor units mount inside the ceiling cavity, so that short lengths of duct handle air from the indoor unit to vents or diffusers around the rooms.

My best advice has always been that a proper duct cleaning is a valuable investment when moving into a home (new or old), after major renovations and if the ducts have never been cleaned before. It is unlikely that there will be increased air flow, as finding major blockage is unusual, but this will eliminate this as a possible concern if there are air flow concerns. It is also true that the "dust" that is cleared out will most likely never have been distributed through the house unless there has been some work done on the ducts. What is cleared out will be pet hair, toys, clothes, construction material, and biological material (small carcasses and/or feces). Once a proper cleaning is done a follow-up is rarely necessary, but up to the home owners discression.
I agree, if you replace (or wash depending on type) your air filters regularly AND vaccum, then you probably don't need the ducts or air coils cleaned. However, if you purchase a pre-owned home, and the previous owners did not regularly change the air filter or vaccum the home, then duct cleaning is worth the expense especially if you are sensitive to allergens. Especially if the previous owners had pets.

WELL, this summer when I opened them up we had black dust spewing from one of the upstairs vents. It resembled the fuzz that comes off new towels. This prompted us to look into duct cleaning. We heard from someone who had it done several times, said it was worthwhile, and knew of a firm that did a good job. Clean Air America sent a single technician for the appointment and after counting registers and ducts gave me a price of $360.00 which included “sanitizing” the system (a $99 additional fee per can used). The small size of the plenum forced him to connect the 8” round vacuum hose from the truck to the 10” square opening from our humidifier unit. In hindsight, a mistake since it reduced the “negative” pressure in the system.

I always get a laugh at anyone claiming to be in the business for any length of time that doesnt understand the importance of cleaning out a ventilation system. Not only for better indoor air quality but for maintaining your heating equipment. I guess it makes more sense to some people that the furnace will just run better with a ton of dust and debris and maybe this wont be a big cause of sytem breakdown and malfunction. I mean really? Maybe this guy got a bad company and or cleaning and is a little jaded but to advise cleaning your grills , which does nothing, and replacing a filter....come on guy.
What about ringworm? If the fungus is as contagious as doctors warn, and the spores can live several months, doesn’t it make sense to spray some sort of fungus killer into the HVAC system to kill the spores that it has sucked in from the air? Duct cleaning would not be helpful at all here; these spores are microscopic and it could actually spread them further. But given how severely contagious ringworm is, body and especially scalp, does anyone make an aerosol product that will clean the system and kill the fungus? One the resident can use, not call an HVAC company; you can’t do that when you are in an apartment. I hear it’s not the same as mold, it is much more difficult. Truth?
My vent covers have lots of mildew. They look bad! I live in a very humid climate in a condo. The handyman here has offered to take those down, wash them, sand, & then spray paint them with a mildew resistant paint. He said that he will leave them off overnight to dry. I am wondering if this is safe to breath the AC blowing out into the open all night??. ! Guess it is better than the mildew!?
I own and live in a mobile home and was told to install a mobile home air condition well I did not want one because the ones for moblie homes are to small,so I install a home air-condidtion and its good for heating and cooling the only thing I do is change is the filter every month or two,What I want to know is how does dirt and dust comes from????

Most people are now aware that indoor air pollution is an issue of growing concern and increased visibility. Many companies are marketing products and services intended to improve the quality of your indoor air. You have probably seen an advertisement, received a coupon in the mail, or been approached directly by a company offering to clean your air ducts as a means of improving your home's indoor air quality. These services typically — but not always — range in cost from $450 to $1,000 per heating and cooling system, depending on:
