I purchased this window unit to replace a 10 year old Frigidaire 8,000 btu unit. When I got the first unit, it was a work horse! Cooled the room to 68 degrees when set on 68. Now, the new one, will only cool to 68 degrees if it's left at 60, on high for 6+ hours. Essentially, it now works exactly the same as the 10 year old version it was replacing. I'm really disappointed in this product and expected more. I doubt this one will last as long as the previous one, which still worked fine. It just didn't work as well as it used to so I thought better safe than sorry, and replaced it. I'll be keeping the other one in storage instead of giving it away as I'd originally planned. I really wish the new one worked as well as I'd hoped it would.
