[This review was collected as part of a promotion.] Replace the lg a/cs I bought by 14 years ago. We used them all the time and they finally wore out. New ones work even better. Very happy.

Verified Purchase:Yes
[This review was collected as part of a promotion.] Great unit for the price, I purchased it for a all season sun room and the dehumidifier option is nice because we do not use the heat or air conditioning modes for about 6 months a year and it keeps the room dry

Noisy
on August 11, 2024
Posted by: GJoeB
from Elma, NY
I bought this a month ago. The first problem was that you have to assemble the exhaust hose ends onto the hose. I could not get the piece that attaches to the window to completely seal onto the hose. Had to use duct tape to completely seal it off from the outside air. I also had to use electrical tape to close off openings on the plastic window insert. The unit also rattles loudly especially when first turned on. It would be nice if there was an option to have the fan stay on as white noise when the compressor shuts off. The unit does cool my bedroom well.
Pros: ease of use

Hey there. We want to ensure your LG portable A/C works correctly so you can stay cool and sleep without the noise. Installing the vent hose kit to the window incorrectly can cause the unit to raddle and be noisy. Check out the owner manual on page 12 on properly connecting the vent hose to the window panel. Check out these tips and tricks to correct the loud rattling here: https://www.lg.com/us/support/help-library/lg-air-conditioner-troubleshooting-loud-noise-from-my-air-conditioner--20153120749468. If this persists, private message us on social media @LGUSSupport with your contact details. We'll be waiting for your message so we can get you through this. ^David
