In 2014 we moved into a house that had a Speed Queen washer and dryer from the early 1990s. At the time I had no idea what a Speed Queen was, but I was definitely impressed with their longevity. They worked great at least until the day we sold that house in 2019 and are likely still going strong.
When we moved into our current house in 2019, it did not come with washer or dryer. I wanted Speed Queen. I did a good amount of research. So mind you, this research might be a bit dated, back to 2019. Below is what I read:
Speed Queen was a tried and true maker of quality products that lasted a long time and that did a darn good job cleaning. Then c.2017 they added a couple of models that may well have still been built to last decades, but they were higher efficiency (less water for washing machine) and seems they just didn’t wash clothes as great as their older models. Perhaps the new models cleaned clothes about as good as a generic competitor, but that generic competitor’s machines were 1/3 - 1/2 the price.
Shortly thereafter, Speed Queen began making a ‘classic’ line that was not high efficiency. It was found to wash clothes the same as older Speed Queens. Model TC5000WN for the washer and model DC5000WG for the dryer.
I bought these models. They’ve been going strong since Fall 2019 and I suspect they’ll be going for a long while. I haven’t noticed any fall off in wash/dry quality from the early ‘90s set that we had. I live in New York and ordered from the authorized retailer, Goedeker's. The product was shipped direct to me from Speed Queen. Goedeker's is not in NY so I didn’t have to pay sales tax, which was a nice savings. The store has since acquired another company and rebranded its name to Appliance Connection, but I suspect that the same general principles apply.
We really like our Speed Queens!
