"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 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:
Nowadays most homes have a central air system with connecting air ducting to move conditioned indoor air throughout the home. Over time, the air system and the connecting air ducting will accumulate dust and other contaminates, which can cause circulation of dirty and polluted indoor air through your home. Out-of-sight and out-of-mind health items that we don’t think much about are dirty air system and air ducts which could be the unhealthiest item in our home.
Make certain that the business has the correct devices and sufficient HEPA filtered vacuum power (2,000 CFMs or more), to appropriately clean your duct. Be tired of business that utilizes little vacuum systems that have a little turning brush on completion of a little vacuum hose with a normal air flow of 150 to 300 cfm or less. Appropriate duct cleaning vacuums are damaging air devices with 2,000 CFMs have 8 inches to 14 inches or bigger, vacuum hoses to record big amounts of dust and particles.
On the other hand there are many more air duct cleaning companies that will properly clean the air system and air ducts and use commercial negative air duct cleaning vacuums with at least 2,000 CFMs of vacuum power and utilize proper agitating tools to move the contaminates within the duct work to be captured with HEPA filters and contained by the air duct cleaning vacuum equipment.
