The number one issue with having an air conditioner blast cold air into your home or office workspace is that they are often not cleaned as thoroughly as they should be. Not changing the filters can cause many different kinds of bacteria and fungi to accumulate.

Air conditioners can also be a breeding ground for black mould, due to the high amount of moisture that builds up from condensation that’s created with all the cool air that passes through.

Mould spores and other bacteria breed when they have both moisture and food (dust, dirt), and your A/C can easily contain both.

A quick fix for this is to make sure your air conditioning unit is cleaned regularly and the filter is also cleaned or changed every couple of months as required.

How this happens

To cool your home or office work space, air is blown over the cold evaporator coils in your air conditioning system. As the air passes over the coils, the moisture in the air condenses and collects on the coils. This moisture collects bacteria, dirt and dust from the air.

This creates a perfect environment for mold, mildew and bacteria to grow and then be blown back into your office’s air.


How to prevent the spread of germs

  • Clean up water damage immediately to prevent the growth of mold
  • Make sure bathroom exhaust fans are running to reduce humidity and prevent moisture
  • Have Alliance Climate Control perform a 19 Point Check of your Air Conditioning System
