Cooling load

Check portable AC before it joins the room load.

Portable cooling can be added in a hurry when an office, server room or shop gets too hot. Check the AC input watts, fans and existing equipment before plugging more in.

Use input watts, not cooling output.

BTU and cooling capacity are not the electrical load. Use the rating label watts or amps for the check.

Check portable AC, fans and existing socket load.

Use this before a portable AC unit is added to an office, server room, shop floor or temporary workspace that already has equipment plugged in.

Cooling output is not the electrical input. Use the watts or amps from the rating label, not BTU or marketing cooling capacity.

Compare portable air conditioners once the socket load has enough margin.
