In years back, air conditioners used to be as simple as just on/off switch with the high, medium and low options. But with the latest technological innovations, the modern air conditioners offer more features with multiple modes of operation.
These multiple options include the cool, dry and fan options. Irrespective of the time of the year, the humidity and temperature levels afford you the freedom to save energy by setting the mode your air conditioner runs on.
Just a simple understanding of every setting helps you in maximizing the most of your air conditioner at a cheaper cost instead of allowing your aircon to blow at full blast making you uncomfortable.
