Bought this June 10, 2019, installed June 20, 2019. So far, it is still working, May 25, 2020. However the remote is dead. I put new batteries in it. I had taken the batteries out over the winter. I couldn't find any info in the booklet or on this website telling me where I can find a replacement remote. I have to say, we used to be big fans of B and D, but in the last year or two, the quality of the products overall has plummeted. We primarily use this for cooling. Installation is easy, however the duct will not stay in the window panel. I have to prop it up with a small bottle to keep it attached. Also, it is extremely noisy. I can't believe the noise it makes. My grandchildren stayed for a few days and were completely unable to sleep in the same room with it. I have no idea why it can't be quieter.
