Every environment may have different types of airborne dirt. A coastal environment, one would expect to find higher concentrations of salt. An office may have printer inks, moisture, paper and fabric fibres. A salon you will find hair and proteins from lotions and hair sprays. All of these contaminants, overtime, will find their way into both refrigeration and air conditioning systems.
Both types of cooling systems circulate air through a refrigerated coil, which is designed to remove heat energy from the environment. Airborne particulates follow the circulating air and are then drawn into the unit. Dirt begins to collect and clog the coil and filter (if fitted).
A dirty heat exchanger, if left untreated, could see energy costs increase by up-to 36%. Other related issues around poorly maintained coils include:
System refrigerant leaks
Higher energy costs
Higher tax on climate change levy’s
Planned Preventative Maintenance (PPM) helps to
Other benefits may also be enjoyed, such as improved Indoor Air Quality fewer particulates in the air and a reduction in potential cross contamination.
Cleaning the filter isn’t enough, it will help, but dirt can find its way into all surfaces within a AC and Fridge.
