Best Air Conditioner 2021 – Buyer’s Guide

Air conditioners are an easy to install and effective way to lower the temperature of a single room in your home.

They work by removing the heat and expelling it out of the room. This differs from ordinary fans, which only move the hot air around the room. They operate until the temperature in the room reaches the desired degree, and then they often turn themselves off, operating again if the temperature rises again.

Most only require an electrical supply plus external ventilation. This can be via a hose either placed outside a window, or through a vent in the wall.

They are ideal if a central air conditioning system is not a practical solution, or if you will only want to cool one room at a time as opposed to the whole house.

All of the air conditioners we have featured below are portable, so can be moved between the rooms in your home:
