is there a relationship between a dirty, contaminated HVAC system and unit efficiency?
Yes. A dirty system is never efficient. In addition, there is more wear and tear on system components in a dirty system. There is a direct relationship between trying to control debris within the unit and efficiency of the system. Many times, a restrictive filter is used to try to prevent a dirty system; however, it doesnt really clean the system or the air and causes an acceleration in energy use. In much the same way, a dirty coil restricts air, promotes microbial growth, and hinders efficient cooling ratio.
