In today’s fast-paced world, maintaining a healthy environment is of paramount importance. One crucial aspect that often goes unnoticed but plays a significant role in ensuring indoor air quality is the air handling unit (AHU). An air handling unit is a vital component of heating, ventilation, and air conditioning (HVAC) systems, responsible for circulating and conditioning the air within buildings. However, over time, these units accumulate dirt, dust, mould, and other contaminants, negatively impacting indoor air quality and overall system efficiency. 

This is where Coolclean comes into the picture, offering comprehensive cleaning and maintenance solutions to promote clean and healthy indoor air. To dive deeper into the air handling unit cleaning, we had the opportunity to chat with Grant one of the Coolclean business manager.

Grant has over 25 years of experience as a food & beverage production hygiene specialist, cooling tower and cooling system manager, heavy industry, light industrial, power generation and commercial institutional applications. Was a qualified air conditioning and refrigeration mechanic with the air force so knows HVAC as well.


Understanding the Air Handling Unit (AHU)

The Air Handling Unit (AHU) is a crucial component of commercial Buildings like hospitals, distribution centres, airports, and schools’ HVAC systems. Its primary function is to circulate and condition the air within a space, ensuring a continuous supply of fresh, filtered, and temperature-controlled air. air handling units consist of various components, including filters, coils, fans, and dampers, all of which work together to regulate indoor air quality and comfort.


The Role of Air Handling Units in Indoor Air Quality

Before delving into the importance of air handling unit cleaning service, it is vital to understand the crucial functions air handling units perform in maintaining indoor air quality:

Air Circulation: air handling units facilitate the distribution of conditioned air throughout a building, ensuring that all areas receive an adequate supply of fresh, temperature-controlled air.

Air Filtration: Equipped with filters, air handling units trap and remove airborne particles, such as dust, pollen, allergens, and microorganisms, preventing them from recirculating within the building.

Humidity Regulation: air handling units help maintain optimal indoor humidity levels, which is vital in preventing mould growth and ensuring comfort for occupants.

Temperature Control: They play a pivotal role in cooling or heating the air, maintaining a consistent and pleasant indoor temperature.



Importance of Air Handling Unit Hygiene Cleaning

Over time, air handling units accumulate dirt, dust, debris, and even moisture, providing a breeding ground for harmful contaminants and microorganisms. Grant explained Several reasons why regularly cleaning your air handling unit can benefit you, your staff, and your business:

Improved Indoor Air Quality

Regular air handling unit cleaning is directly linked to improved indoor air quality. By removing accumulated pollutants, allergens, and microorganisms, the air that circulates within the building becomes cleaner and healthier. This, in turn, reduces the risk of respiratory issues, allergies, and other health problems among occupants.

Energy Efficiency

Dirty air handling units tend to work harder to provide the same level of conditioned air, this increased strain leads to higher energy consumption and, consequently, increased utility bills, after 5 years, a non-cleaned air handling unit can use up to 50% more electricity. A clean air handling unit operates efficiently, reducing energy consumption and resulting in cost savings. 

Extending Equipment Life

Proper maintenance and cleaning of air handling units extend their lifespan. Dust and debris accumulation can lead to mechanical issues and premature wear and tear, which can be costly to repair or replace. Routine cleaning helps avoid these problems and ensures the longevity of the equipment.

Mould Prevention

Stagnant water and accumulated moisture within air handling units can promote mould growth. Mold spores, when released into the air, can cause respiratory problems and allergies. Regular cleaning eliminates moisture pockets and prevents mould growth, thereby promoting a healthier indoor environment. ​​

Compliance with Health and Safety Standards

In many commercial and industrial settings, compliance with health and safety standards is mandatory. Regular air handling unit cleaning ensures that buildings meet these requirements and provide a safe environment for occupants and employees.
