How often you should clean your air ducts depends on your situation. If you or someone in the home has asthma or is acutely allergic to certain airborne materials or pollen, regular duct cleaning may be helpful. The Environmental Protection Agency doesn’t have an official position on the necessity of air duct cleaning unless the ducts have been contaminated by rodents, insects or mold, or you are aware of particles blowing out through the vents. The EPA recommends you have your air ducts cleaned on an as-needed basis. The National Air Duct Cleaners Association (NADCA) suggests having air ducts cleaned every three to five years.
"Our electric bill has dropped around seventy dollars a month and that is with the a/c set at 76 degrees. I know it will be lower next summer since I am now taking advantage of the energy start setting the thermostat has. Also our son's coughing at night has stopped and I think it is due in part to the clean air effects filtration system that we got when we purchased the system. We are very happy with our new A/C system. Also we got a refund from Clay electric for having a 17 SEER system and we will get to write some off on our taxed next year."
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.

"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." 
Of the cleaning services in which we are proud to be specialists, air duct cleaning is by far the one that requires the most trust between the consumer and the air duct cleaning service provider.  There are many unscrupulous air duct cleaning companies purporting to be something they are not, many advertisements using unrealistic scare tactics, and of course bait and switch tactics are prevalent in the industry.  You need to feel confident in the professionalism of the firm you hire to clean your air ducts because you are asking someone to clean the inside of your duct work, where it can be difficult to see the results of the job.
