"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."
"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." 
"This a very professional company that came the next day after being contacted late in the day prior. The two guys that came to the door that did the work were well dressed and very courteous. They cleaned my diver vent and it works perfectly. I have their literature and will be calling them when I m ready for duct cleaning. Nice equipment too! Thanks for the good work. Nice not to have scroungy guys showing up at the door. "
