Coils of a commercial HVAC unit are fragile and must remain in perfect condition for the unit to operate as designed. Damage to the condenser coils can prevent the unit from working properly and result in overwork, malfunction and eventual breakdown.

HVAC units inevitably accumulate grime and moisture over time and require cleaning and service. This is particularly true for rooftop units that are exposed continuously to Chicago’s extreme weather. Regular mechanical HVAC maintenance is required to keep your unit operating efficiently, and should always be performed by a professional.

Why Cleaning an HVAC Unit’s Coils Is Important

Three reasons why regular maintenance and cleaning of your HVAC system’s coils is important are:

More energy-efficiency:  Cleaning coils and other parts allows for unencumbered flow and operation of the heating and air conditioning system. As a result, the system works more efficiently, using less energy to operate.

Cleaner air: Removing grime and dust accumulation from the system is essential to producing clean air. In addition, pollen, mold spores, and other contaminants may appear in evaporator and condenser coils. Indoor air quality is essential to the comfort and health of employees and residents.

Extended equipment life: A well-maintained system is more effective and will stay in service longer. Preventative HVAC maintenance saves money on emergency repairs and keeps the equipment running longer.

Coil Cleaning Process

Experience and careful attention are necessary for cleaning the coils and to avoid damaging the fins. Depending upon the degree of grime present, the process may involve simple air cleaning or very light detergent and gentle water cleaning. More substantial dirt accumulation needs more aggressive service with a careful steam cleaning or stronger detergents and careful rinsing.

Chemical solutions are be used to remove toughest particulates. But caution must be exercised to ensure all residue is removed before operating again.

All cleaning methods require experience to ensure that the system is fully cleaned, all dirt, soap and chemical solutions are removed, and the system has not been damaged.

Coil Cleaning by Professionals

Conditions differ from location to location but generally cleaning should be performed every four months to ensure clean and efficient performance. The process must be performed by licensed professionals since proper cleaning requires the specific equipment and techniques. Cleaning is best performed simultaneous with other system testing and preventative maintenance procedures.

Testing, inspection and worn parts replacement are also important functions to keep the system working in top working condition. With the right tools and knowledge, a professional licensed technician can ensure your system remains working properly.
