Air Conditioning Cleaning for Offices

There’s nothing like a clean office space to welcome your staff at the start of every working day. If the air in your office is stale or stuffy consider a thorough clean of your air conditioning system & ductwork.

Fresh air plays a crucial role in offering your workers a safe & comfortable office environment.

Over time, duct systems become fouled and can affect the quality of air you breathe in your workplace. By cleaning the air conditioning you can control the quality of air produced in your office premises. A scheduled air conditioning maintenance programme is the easiest way to keep your premises safe for all your staff.


Air Conditioning Cleaning for Warehouses, Factories & Large Premises

How often you should clean your workplace’s air conditioning will depend on the following:

  • the kind of air con system you have
  • the number of people occupying the area
  • the overall indoor air quality
  • the level of air pollution and construction around the facility.


The air con filter traps particles and contaminants that could badly affect air quality, such as dirt, dust, pollen, mould, bacteria and microorganisms.

The air filter is therefore an important, but often an overlooked component of an air conditioner or HVAC system. Air conditioner or HVAC system filters should be checked and possibly be replaced every one to two months. If you have employees who suffer light to moderate allergies, the air filter should be changed more often. Factories, warehouses or industrial facilities who need cool air temperatures for the preparation and storage of foods may need to replace their air filters every month.

Dirty air filters in your workplace can cause the air quality to decline, leading to foul or mildew odours and allergic reactions in your employees, such as runny nose, coughing or sneezing.

As a general rule, you should clean your air conditioner’s air filter within an indoor area every two months. If the air conditioner is located in a more dusty or polluted place, cleaning your filters must be done monthly or more regularly.
