Promptly received our electriq Compact 9000 BTU Portable Air Conditioner unit but on using it, it was soon obvious that all was not well. The noise level when the compressor ran was, to say the least, very noisy, in fact more of a 'rattle' as if something loose internally. I sent video to Appliances Direct who then arranged collection for checking. The day after collection I was informed that the unit was indeed faulty and a replacement dispatched. On switching on the replacement the lack of noise was a very welcome sign. The unit is not much noisier than a free standing fan we previously used. Wouldn't hesitate to purchase further items as pricing very competitive and service support second to non...Well done in this age of 'automation' nice to deal with a company that has humans to resolve issues quickly!
