After previously purchasing the 10,000 btu equivalent to this 6,000 but model. We knew the pros and cons. The units both work well. But are a little noiser than expected. But they do move a great amount of air. There is little or no compressor noise. A definite plus. I had to call Frigidaire support because the 6k model was missing the air filter. Happy to say that they responded by sending one to us. Happy with their service so far. We did purchase the extended warrantee on both units. Hope not to need to use it. Very attractive units by the way. [This review was collected as part of a promotion.]
