Yes, they can work very well but you have to be aware of how to position them for best cooling effect: you can't just stand a portable air conditioning unit in the middle of the room, as if it was a room heater.

Always place the portable AC unit next to a window opening (or similar) so that all (100%) of the hot air from the unit gets sent outside the room you are trying to cool.

If you let any of the hot air from the unit get back into the room you will just be wasting electricity.

There are some tricks to get the most out of a portable AC. First, insulate the exhaust hose. Even something simply like wrapping the exhaust hose with towels, or modifying a hot water heater insulation blanket to cover the exhaust hose can yield huge improvements in the performance of the air conditioner because the exhaust hose radiates a lot of heat back into the room during normal operation.

Another hint - I nearly always recommend that our customers buy a dual hose portable air conditioner because they are more efficient and typically cool better than single hose units.

What air conditioning tools are needed for connection?

This answer depends on if the air conditioner is portable or permanent. With a portable air conditioner you need a hose (if equipped, this comes with the free standing air conditioners) to vent out the hot air. But with the air conditioner that sits in the window you need a screw driver, screws and plastic curtains that go around the air conditioner to block off the rest of the window. On a permanent air conditioner that is built in the house it is best to have a professional install it because they are licensed to do so and will be equipped with all the tools needed.
