Regular maintenance is crucial in the upkeep of any heating, ventilation, and air conditioning (HVAC) system installed in an industrial, commercial, or health care environment.

Cleaning is especially critical in industrial settings, where HVAC components become dirty more quickly, and in health care environments, where patient comfort and cleanliness are primary concerns. Coil cleaning — maintenance of the evaporator and condenser coils — is particularly important.

Coil Cleaning Methods

Just as HVAC coils come in many variations, so too do cleaning materials and maintenance methods. It’s essential to clean your coils with the proper cleaner. Cleaners fall into one of four different categories — acids, alkalines, solvents, and detergents.

The type of cleaner and the precise formulation best for your system will vary depending on the coil material, its installation environment, its operation, and the type of dirt and contaminants with which it is soiled. Using the wrong type of cleaner or cleaning method will reduce the effectiveness of your coils and shorten their lifespan.

Introducing Coil Flow Max for Large Plugged Coils

Large plugged coils — thicker than four inches — are very common in commercial, industrial, and health care HVAC systems, especially for critical care applications such as operating rooms. They are also notoriously difficult to clean.

Because of this, large coils are often not cleaned thoroughly or become damaged during the cleaning process. In fact, replacement used to be the only viable solution for these situations.

For decades, our team has observed this problem time and time again, so we’ve spent years developing a solution. The result is Coil Flow Max — a proprietary, patent-pending technology only available from Carolina Filters.

This unique coil-cleaning method guarantees full cleaning of coils without ever damaging coils or fins. Coil Flow Max extends coil life, provides better air flow and humidity control, and allows for higher cost and energy savings.

Planning Ahead

A regular cleaning schedule must be established and adhered to in order to properly maintain an HVAC system. While it’s important to clean all components, including vents and ducting, coil cleaning should be the focus of any maintenance plan.

Coils play a vital role in HVAC systems, acting as the actual heat conversion points. Because of this, dirty coils can cause more serious detriments than other dirty components. The optimal frequency of coil cleaning — and the cleaning of your entire HVAC system — depends on several factors:

  • Their overall environment — Coils in an HVAC system at a manufacturing facility will require cleaning considerably more often than at a commercial store or in a hospital environment.
  • Their precise environment — Condenser coils are commonly located outdoors, subjected to the elements such as extreme temperatures, sun, and dirt.
  • Range of use — Cooling a retail environment to 75 degrees taxes an HVAC system considerably less (and also costs less and requires less cleaning) than cooling a manufacturing facility with heat-generating equipment that runs 24 hours a day.

Discuss the application of your coils with one of Carolina Filters’ knowledgeable technicians; they will help you develop a custom maintenance schedule that’s right for you. If properly maintained, you’ll find your HVAC system working with more energy efficiency, for longer periods of time, and with fewer component failures and unplanned maintenance — all of which will ultimately reduce your overall maintenance costs.
