HVAC Steam Coil Cleaning

“The Steam Revolution” in Cleaning

HVAC steam cleaning for schools in Malaysia

Here in IAQ Diagnostics, we choose what is best for your HVAC system and we choose steam cleaning because the air that flows through the coils inside the MVAC system contains dust, pollen, and other particles. Heat alone ensures that the bonding between microorganisms and the surface structure is broken down while the low pressure allows the steam to deeply penetrate difficult to reach areas.

We do not need to use any harmful chemicals, and yet, it can still remove and clean the dirt that builds up deep inside the system. It effectively removes the grime which, otherwise, is extremely hard to remove from the HVAC coils.

Our Process

The air that flows through the coils inside the HVAC system contains dust, pollen, and other particles. Since the coils inside are usually wet or damp due to the humidification process, dirt and bacteria easily sticks to the coils. This dirt, when gathered inside, affects the efficacy of the system.

How Do We Operate

Preparation

The area will be contained to retain heat and humidity out of the indoor environment. After that, both electrical components and ductwork are concealed to shield them from heat.

Testing

Coil Cleanliness Verification Test (CCVT) is conducted to identify which coil is badly impacted by performing the test repetitively. This indication is also useful to report about the state of the coil before they are cleaned.

Measurement & Verification (M&V) Report

Contain CCVT before, during and after testing recorded, QA job description checklist, photos and suggestions for any remaining problems that may need recognition. This report is provided for each AHU that has been cleaned, in detail and emphasizes which it allows data to be tracked easily on the tools.

Frequently Asked Questions

Steam cleaning cleans every layer of the coil, removes contaminants, debris and pathogens that struck inside the coil compared to chemical coil cleaning that only removes dirt that lies on the surface.
Coil cleaning is necessary to ensure that the HVAC system could operate at its optimal efficiency, by being able to supply clean air (air that has been filtered using coil). The failure of maintaining the coil (cleaning the coil, removes dirt) will reduce the lifespan and indirectly distribute uncleaned air to be breathed by the occupants.

HVAC coil cleaning needs to be serviced at least once a year. 

Yes. When HVAC coil cleaning is being done or in other words, serviced, it will help in reducing the energy maximization as the HVAC system could operate at its optimal efficiency. One of the causes of bills rose higher than its normal when the HVAC system needed to push its military operations to the max in order to suction adequate air to be supplied to the facilities.
