Recent technical articles by ASHRAE and indoor air quality associations point out the far-‐reaching effects of poor air conditioning hygiene on building owners and occupants. Most ignore the articles, figuring they are just hype, with no real basis. Besides, most imagine, doing something with hygiene is not really financially sound.
Far from being just a buzzword, poor hygiene costs real money in terms of higher monthly energy expenditures. Simply put: A dirty A/C interior causes your energy cost to increase every month up to 20% higher. While this may not be a problem for a single home unit, it mounts up when the owner has several large A/C units, or in the case of hotels having 100’s of units. Here we are not talking about ten dollars per month increase, but added expenses in the thousands per month.
In addition to paying more for electricity costs, another gift is the presence of moldy odors and eventual overflows of HVAC water onto the property. This in turn causes property damage and deposits odor causing mold spores onto property surfaces (ceilings, wood, carpeting, wallpaper, etc.)
For years the HVAC air handler has been disregarded in terms of cleanliness and hygiene. Maintenance staffs have typically looked at the units as a necessary evil to maintain. Most of this is due to ignorance of essential efficiency aspects as well as health aspects of the AC units.
