I did a lot of research into the different options recently for my room as I can’t have the window open due to privacy. My room gets boiling and it does affect the wax. I use a regular tower fan on top of unit and have it blowing towards my couch. It helps. I also open the door and window between clients to allow more air to circulate but need to space out clients to allow this to happen. I read air coolers which take water or ice cause more humidity in a room that has no ventilation and given how humid my room currently gets in this hot weather, It would only add to that. Air con requires an unsightly hose to be thrown through an open window which I can’t do due to privacy. Or built in to the room which I believe requires an ugly unit on my outside wall similar to what I have in my conservatory. Being residential, with a front room, I don’t want this, so it seems I’m stuck with spacing out clients and using a fan. Air con is expensive to install and to run. Hopefully you’ll have more options than I.
