He removed areas of dust and grime from the grill of this large air return to create a distressed emoji. The photo illustrates just how filthy air returns and other components of HVAC systems can get if not regularly cleaned and maintained.  [Complete HVAC system cleaning](http://service-techcorp.com/services/hvac-system-cleaning/) including air duct cleaning improves both indoor air quality and energy consumption. According to the National Air Duct Cleaners Association (NADCA), cleaning lightly soiled systems and changing the filters can result in energy savings of 11% and up to 30% for heavily soiled systems.   What is the state of your HVAC system?   ####  Call [tel:+1-800-992-9302](tel:+1-800-992-9302) or email [info@service-techcorp.com](mailto:info@service-techcorp.com) for a FREE ESTIMATE.   ## Request an Estimate ## Clear the Air With a Reliable Cleaning Partner Minimize machine downtime and maintain a clean and safe environment for your employees with an HVAC system cleaning partner backed by a history built on hard work, integrity and a commitment to excellent service.
