We are sorry to hear this, John ! Our portable air conditioners work best in enclosed, well insulated spaces. Room environment conditions such as ceiling height, sunlight, number of windows/ doors and level of insulation can affect cooling efficiency and there are ways to increase the capacity of these units. There could be other reasons for the unit to not cool- temperature setting could be too high, or the exhaust hose may need re-installation to avoid the heat from coming back into the room.
Like any other electrical device, this portable air conditioner will create some sound when operating due to the powerful compressor working to cool the space you need it to.
Please do give us a call at 1-800-474-2147, Monday - Friday 8:30 AM - 5:30 PM (EST), or send us an email at firstname.lastname@example.org with the reference code number THC1001. We look forward to making this right for you. Thank You !
