There are three options for air conditioners. These are windowed, split system, and portable. Window models are installed directly inside the window. They are more suitable for small rooms.
Split systems have more power and efficiency than window air conditioners. They have two blocks: external block – on the street, internal block – inside the house.
Portable air conditioners are ideal for small apartments. True, they may be less powerful than other types of devices.
When choosing an air conditioner, pay attention to a number of factors. This is the size of the device (choose the one that is suitable for a particular room), energy efficiency (its indicators must be high), functions (heating, air purification, dehumidification), budget (the price of the air conditioner depends on its energy efficiency, performance).
