Why isnt yearly cleaning of my heating, ventilation and air conditioning system enough?

Cleaning is very important and does provide some protection against dangerous contamination of your system. As soon as your system is turned back on after cleaning the dangerous micro-organisms are starting to colonise surfaces. It only takes a small amount of water for these organisms to multiple through your system. AerisGuard is an insurance policy that will stop any dangerous colonization from occurring. The protective coating stops any potential growth from occurring for up to a year. A yearly clean and treatment delivers peace of mind to you and your family.  more
