Negative pressure air duct cleaning is a process in which the ducts are cleaned by hand in concert with compressed air tools to dislodge dirt and debris, which is then vacuumed up and removed. It is considered a superior cleaning method in its efficiency and in preventing dislodged debris from escaping the ducts and contaminating the air in the residence.

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:
   Jacksonville dryer vent cleaning service technicians are trained to do a complete dryer vent cleaning. If your dryer vent vents out to the roof, most of the buildup is in the "gooseneck" shaped cap sticking out of your roof. That is why it is neccessary for us to either go up on the roof or in the attic and clean the dryer vent cap out before cleaning the rest of the duct. Beware of dryer vent cleaning services that clean the duct only from the laundry room because the brushes or blower will push the lint up to the roof vent and compact it even more.
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.
We highly recommend using a Florida Certified Mechanical Contractor to inspect and clean your air system. As a certified Mechanical Contractor the technicians, are properly trained to decontaminate your air system and not only can they properly clean your air system due to their extensive knowledge and experience with air systems and indoor air quality, but they can also alert you of any additional areas that might need attention to improve upon your indoor air quality such as; filtration considerations, damage, structural air flow problems, or inefficiencies of your present system. In more humid and hot climates, you will want to have your air systems inspected and service, at least every season, to assure that your air system and air ducts is clean of debris providing good indoor air quality.
Our technique cleans your entire dryer vent system twice – once from the outside and once from the inside – so you can be sure the job has been done right.  According to dryer manufacturers, your dryer vent must be producing about 96 cubic feet of air per minute at a velocity of 1100 feet per minute in order for your dryer to be operating efficiently and safely.  We test your system using a sophisticated thermo-anemometer to be sure that you are getting the proper air velocity and volume at the vent cap.
Keep in mind; consider your air system as the lungs of your house. Think about the type of business that you desire to manage your house’s lungs and your indoor air quality within your house. Have the total air system occasionally checked for polluted duct and have it correctly preserved so your Heating and Air System can offer your household with great air quality for many years to come. Certified duct cleaners will follow rigorous requirements set by the National Air Duct Cleaners Association. Enabling an unqualified service provider to clean your ducts could be even worse than not having them cleaned at all. More particles could be separated and launched into your house or your HVAC system could be harmed.

While a thorough air duct cleaning process must be done by professionally qualified service companies, there are a few steps you can take to help maintain the cleanliness of your heating and air conditioning system. One is to change your air filters regularly and make sure you have the right filters for your home and HVAC system. You should also have your system professionally inspected every one to two years to have a technician determine if your air ducts need to be cleaned. In between scheduled maintenance or inspections, you can do a visual check yourself by removing a wall or floor register and shining a flashlight inside the duct. If you can see debris, dirt or dust, it’s time to have your ducts cleaned by a licensed, insured HVAC professional.
Remember; think about your air system as the lungs of your home. Then consider the type of company that you want to handle your home’s lungs and your indoor air quality within your home. Have the complete air system periodically inspected for contaminated duct work and have it properly maintained so your Heating and Air System can provide your family with good air quality for years to come. Qualified air duct cleaners will follow strict standards set by the National Air Duct Cleaners Association. Allowing an unqualified contractor to clean your ducts could be worse than not having them cleaned at all. More particles could be broken up and released into your home or your HVAC system could be damaged.

Chances exist that lint that has in fact been restricting the exhaust vent over a prolonged time period can cause overheating which in turn can cause a fire. The establish of lint that occurs over a prolonged amount of time is not merely a fire threat, it is also a clothing dryer problem that gradually steals the energy efficiency of the clothes dryer and gradually cost you significantly more money.
