How to choose the correct place for wall-mounted air conditioner installation?

The air conditioner comprises two units: an outdoor unit and an indoor unit. The outdoor unit has a condenser coil. When the refrigerant flows into the evaporator, the condenser coil releases heat outside. The condenser coil needs an open airflow place and a good ventilation system below are the best practices:

Choose a daytime shaded place and avoid all heat-producing resources like light bulbs for the indoor unit too

  • The thermostat detects heat inside a space. The Bulbs and other heat-generating resources release heat, which is detected by a thermostat and results in false readings of the thermostat.
  • To avoid false readings, maintain a distance of up to three feet of all heat-generating resources from the thermostat
  • Install air conditioner 7 feet above the floor
  • Avoid placing any objects in the path of airflow to you
  • Some air conditioners can be noisy. If you choose to place a wall-mount unit in a quiet place, select the type with less noise.
  • Must choose an open surrounding place to mount the outdoor unit. The open place provides hassle-free installation and easy maintenance of the air conditioner
