Why Cleaning Your Commercial Air Conditioning System Is Important?
Queensland’s weather can be brutal with high humidity during the summer and high dust levels during the dryer months. Changes in temperature can have a significant impact on indoor environment resulting in several human responses, including thermal comfort, perceived air quality, sick building syndrome symptoms and productivity. As a business owner, you try to make your employees work space as comfortable as possible. So, when employees complain about being too hot or too cold your first instinct is to reach for the AC remote. But did you know that a 1 degree change in office temperature can impact employee productivity?
Indoor air temperature is a fundamental factor in determining indoor environment. Numerous studies of office and lab environments have found a direct relationship between cooler office temperatures and employee task performance. More specifically, a 2006 meta-study found that the highest productivity performance increase is at a temperature of around 21-22 degrees celsius, whereas performance decreases by 2% per 1 degree increase above temperatures of 25-32 degrees celsius. For example, at the temperature of 30oC the performance is only 91.1% of the maximum. Keeping on top of your business’s AC hygiene will not only improve productivity it can reduce your bottom line.
Environmental change coupled with inadequate AC hygiene creates the perfect conditions for commercial HVAC pollution. Only through routine air conditioning cleaning can indoor air pollution be abated and system efficiency, extended asset life and reduced energy savings result. More importantly, AC system hygiene treats toxic chemical, mould and bacterial contamination, preventing its spread to the occupied space. But DIY cleaning isn’t enough. Only professional AC cleaning can provide long term protection from mould and bacterial recontamination. This involves a total system clean that requires HEPA filtered vacuum removal of dust contamination from the AC units - filters, internal components of the Air Handling unit and the ductwork, as well as the application of a proven anti-microbial, multi-enzyme treatment product to the coils.
