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.

Knowing that your home is clean is a great feeling. Knowing that your home air is clean is an even better feeling. Having your air ducts cleaned regularly is key to making your home safer and more comfortable for you and your family. Since we breathe in around 10,000 liters of air a day, the quality of the air in our homes greatly affects our quality of life. So we mean business when we say that air-duct cleaning is a must. Air duct cleaning involves the general maintenance and washing of various heating and cooling system components, such as the supply and return air ducts of your system. It’s just a matter of time before HVAC components get contaminated with pollen, dust particles, mold (if moisture is present), and other debris. These can bring on allergy symptoms and affect your health in other negative ways, so make air-duct cleaning a priority for the healthiest home possible.
Ensuring that your duct and air systems will be appropriately cleaned with the right devices, workers has the appropriate training and is a Florida accredited Mechanical Contractor which has the knowledge in cleaning your house or structure, is a little cost to spend for the possible health positive aspects for you, your household, or the residents of the structure.
"Energy is consumed by HVAC systems through a number of processes. Air is typically distributed through the ductwork via an electrically‐powered fan. Cooling coils remove heat from the air. Heating coils add heat to the air. Through normal HVAC usage, particulates in the air slowlycollects on the surfaces of various HVAC components, resulting in a gradual loss of energy efficiency. Some loss of efficiency via a single dirty component may be minor. When the loss through each component is added up, however, the impact could be considerable. Generally, the greater the buildup, the greater the energy loss. Removal of the buildup of particulate on HVAC components restores energy performance to the system." 
If moisture is present in your air conditioning system, there is greater potential for growth of mold and the subsequent release of spores, which can cause allergic reactions and other symptoms. That’s why it’s so important to have your ducts cleaned properly by professionals. Overlooking a component in a contaminated system can result in recontamination and the return of air quality problems.

There is some disagreement within the industry about the best method for cleaning air ducts.  The two schools of thought are the “negative air” approach and the rotary brush and vacuum approach.  We believe that both air duct cleaning methods can achieve great results in most situations when performed properly by competent technicians.  However, our focus has always been on high quality residential service.  The type of residential duct work commonly used in homes in the South poses unique challenges to duct cleaners because it is soft, flexible, and does not go in straight lines.  Firms using the negative air approach are especially challenged by this type of duct work, as that process was originally designed to work well on the rigid metal duct work commonly found in the North and in large commercial buildings.  The tools used to agitate the duct work in negative air cleaning are very difficult to get all the way into your duct work and can damage the lining of the ducts we find in most residences in the greater Jacksonville area.
