I did the initial research and writing for this guide back in 2015 while I was still living in Victoria, British Columbia. I still have nightmares about how badly my knees hurt after crawling around on the floor all day with HVAC diagnostic hardware. Happily, my search for a good fan was so complete and the data I grabbed so conclusive that I didn't need to run the tests again this summer--fans are a slow moving category. It's rare that new, meaningful models or updates to the technology are introduced.
As such, The Sweethome saw fit to syndicate my guide with the good folks at Engadget. If you're suffering in the heat and need some relief, one of the pieces of hardware profiled here should help you out.
