There are many misconceptions out there about air conditioning. Here we debunk 5 common misconceptions and set the record straight.

MYTH 1: Most air conditioners pull air from the outside.

FACT: Indoor units recycle the air from inside and do not pull air from outside unless it is a commercial application. The indoor unit of the air conditioner typically features a return air intake grille that has a filter to catch dust and other debris whilst still allowing air to pass through. The air then passes over refrigerant-filled copper coils which absorb excess heat from the air. The now cooled air is pushed back into the room. The outdoor unit fan then takes the heat out of the coils and the whole process starts again.

MYTH 2: A bigger air conditioning system is better.

FACT: Before purchasing an air conditioning system make sure it is suitable for the size of your home or designated room. An oversized unit, even if it has a high-efficiency rating, may consume more power, but can cycle on/off more frequently causing faster wear and tear on the system. When shopping for a new system take room measurements with you, so the specialist can advise what’s the best fit for your requirements.

MYTH 3: A low thermostat setting cools the home faster.

FACT: Selecting the coldest setting will not cool the home faster and can use unnecessary power for minimal comfort gains. Fujitsu recommends setting the air conditioner above 23 degrees Celsius to create a comfortable environment whilst minimising energy consumption. 

MYTH 4:  Air conditioners only cool 

FACT: Installing a reverse cycle air conditioning system enables you to cool and heat the home. Compared to electric heaters, an air conditioner won’t overheat a room as it distributes air evenly around a room and responds to the thermostat to control the set temperature and create a comfortable environment at any time of the year.  

MYTH 5: The location of your wall mounted air conditioner doesn’t impact performance

FACT: Where you have wall mounted air conditioners installed in a room can significantly impact thermostat performance and air distribution. It is recommended that the indoor unit be located away from obstructions, direct sunlight, light fixtures, and other electrical appliances, as this can affect accurate temperature sensing and delivery of the conditioned air.
