A Box Air Conditioner functions by pulling air from the room through a filter, separating the clean air from any dust particles and over the cooling coil. The cooling coil serves 3 primary functions: to drop the temperature of the air that passes over it which in turn, cools down the air being blown back out of the unit removing moisture from the air dropping the humidity levels in the room and in winter worming the room. To maintain this process at maximum efficiency, it is important to invest in regular cleaning of your air con unit for 2 key reasons:
- As the filter serves to catch unwanted dust particles, over time it will begin to build up with dirt and dust and become blocked. This will decrease the amount of air passing through the filter meaning the air conditioner will need to use more power to suck the air in and push the air back out into the room. In addition, the air that does get blown back out into the room passes through a dirty filter and will collect some of this dust on the way out, circulating it back into your home.
- As the air passes over the cooling coil, dew will develop on the cooling coil’s surface, each time you turn your unit on, this process will continue to repeat until the build-up of dew builds a barrier, preventing the warm air from cooling down effectively. This added moisture on the cooling coil also creates a breeding ground for harmful bacteria and mould which become harmful contaminants that are blown back out of the unit and into your air.
