The amount of time air duct cleaning takes can depend on how extensive your duct system is, how old your air ducts are, and whether they have ever been cleaned. On average, expect a standard size home (between 2,000 and 3,000 square feet) to take 2-5 hours for one to two technicians to clean. Here are the proper protocol and equipment you should expect from a professional duct cleaning service, as recommended by the Environmental Protection Agency:

Anyone who has ever seen the amount of lint that can come out of a dryer venting system during a professional cleaning would not hesitate for even a second to schedule an annual dryer vent cleaning. Dryer lint build-up is one of the most common causes of house fires, but because the dryer vent is hidden from view, it is too easy to put out of mind. However, there can be an immense amount of lint jammed inside your dryer’s venting pipe. A highly-combustible material, lint can become a very real fire hazard. The chimney professionals at Hudson Chimney have also seen blockages in dryer exhaust vents from nests of small animals and insects and damages to the venting system or an improper connection. A compromised vent will not exhaust properly to the outside. Accumulated lint can lead to reduced airflow and this can cause overheating which could easily start a fire. Most people assume that their dryer’s lint trap does a good enough job when it comes to catching lint, and while it generally does, “good enough” has not been enough for some. U.S. fire departments report an estimated 2,900 clothes dryer fires in residential buildings each year, causing an estimated 5 deaths, 100 injuries and $35 million in property loss.

Q. Just bought an older house. When we turn on the whole house fan, even with lots of windows open, some air is still drawn through our vents. This causes severe alergy attacks for my wife. The previous owners never had the furnace serviced, weren't the cleanest people, and had several cats. I can only imagine how nast all of the air ducts are. I cleaned out a couple of the reurn ducts and they were nasty with dust and construction debris. I want to have the system cleaned out well. I've gotten several quotes that vary pretty greatly in cost $179-$450. We have a small home with a finished basement that also has heating ducts. I want to choose a service that will do a great job, but have heard that some do a much better job than others. How do I know what to look for, or ask for in a good air duct cleaning service?

If you’re concerned about dust, allergens or mold, it may be time to have your air ducts cleaned. The national average cost for air duct cleaning ranges from $190 to $250. Air duct cleaning costs will vary based on a number of factors such as your location in the country, the age and condition of your air ducts, the number of linear feet to be cleaned, and any repairs your ducts may need. HVAC cleaning companies should clearly outline what is included in their services and at what rate, so always make sure you understand and have a written agreement before work begins. Here are some examples of average air duct cleaning costs:
The first step is to clean the lint trap after every load of laundry. By doing this simple cleaning regularly, you will avoid 90% of dryer vent problems. You should perform extensive cleaning annually, or sooner if you suspect a problem. Unplug your dryer and pull it out from the wall, then disconnect the exhaust tube from the dryer and the wall, and clean it with a vacuum.
Our air duct cleaning technicians check for dust, dirt, pollen, animal dander and other airborne contaminants that are pulled into your HVAC system every time the furnace or air conditioner runs. Over time, they build up inside your ductwork, making your air duct system a breeding ground for mold spores, bacteria, fungus, mildew and other microbes, which are then re-circulated through your home, impacting the health and comfort of your family.
With your air system and ventilation ducts in a consistent cleaned state, you and those in your household can be in much healthier or at least lessen the signs experienced when the indoor air system was filthy and polluted. In addition to enhancing health associated signs, great indoor air quality in the house can cause much better breathing for much deeper and undisturbed sleep. According to some physicians, enhanced undisturbed sleep can result in a much healthier life in general. While in many cases bad indoor air quality can be connected to asthma.
To be honest, the price was much higher than I expected or planned for. But I was impressed by the thorough attention to detail, even in the inspection made before quoting a price, and the professionalism and devotion to quality service that I could see in Mr. Stewart and his team. I suspect that others may have convinced me to add services for an additional cost that were included with his service, so I decided to go for the quality he offered and we were very happy with his detailed and thorough cleaning. The tobacco odor removal in a separate residence was the only thing that didn't seem to be as effective as expected but he came back to try again so I appreciate that. Overall, we're very happy with the cleaning and highly recommend this company.
These are business who are more thinking about getting your cash, through deceptive ads or mailers than really doing the work appropriately and enhancing your indoor air. The really even worse thing you can do is to employ a business that might really develop more of an indoor air issue for you and your household due to incorrect cleaning or usage of inferior duct cleaning vacuums without any more vacuum power than a big Wet/Dry vacuum with a turning brush connected at the end of the hose, or make use of a who is not effectively accredited or accredited to clean air systems. Be specifically suspicious of business promoting the low one cost duct cleaning company, it’s like offering one cost to paint the outside of your house whether it be 1 story or numerous stories high.
Assuring that your air ducts and air systems will be properly cleaned with the correct equipment, personnel has the proper training and is a Florida licensed Mechanical Contractor and that has the expertise in cleaning your home or building, is a small price to pay for the possible health benefits for you, your family, or the occupants of the building.
Ensuring your air ducts are clean is one of the most simple ways to keep a clean house and healthy body. Since dust and other contaniments pass through your air ducts five to seven times a day, they can contribute to different health problems. You may notice the most common problems include eye and nose irritation, coughing, asthma, and especially allergic reactions. The sooner you have your air ducts cleaned, the sooner you can breathe easy. It’s important to note that when air ducts are being cleaned, all components of the system should be completely inspected and cleaned, including cooling coils, fans, heat exchangers, registers, grilles, diffusers, and air ducts.
The best way to know if your cleaning was effective is through improved performance of your HVAC system, ideally. You can have before-and-after pictures taken of the ducts (make sure they are of the intake ducts - the ducts that return air into your room), motor and coils. Another tip is smell – sniff the ducts before and after the work is done. Outside of noticeably improved performance, smell and visual evidence are your best indicators.
These are companies who are more interested in getting your money, through misleading advertisements or “bait and switch” mailers than actually doing the work properly and improving your indoor air. The very worse thing you can do is to hire a company that may actually create more of an indoor air problem for you and your family due to improper cleaning or use of inferior air duct cleaning vacuums with no more vacuum power than a large Wet/Dry vacuum with a rotating brush attached at the end of the hose, or use a “carpet cleaner” who is not properly licensed or certified to clean air systems. Be especially suspicious of companies advertising low one price duct cleaning service, it’s like providing a one price to paint the exterior of your home whether it be 1 story or several stories high.
