I hate to be the wet blanket while you're busy congratualting yourself, but a question comes to mind. What happened to your old air conditioners and washer/dryer units? Unless I am mistaken, these were working appliances that you tossed into a landfill? Interesting....
Ummm, no...one of our air conditioners was not functioning (the previous owners had illegally overfilled it with freon to get it cooling at all, just to get it past the home inspection), and the other two were in such bad shape (the condensers were no longer pulling humidity out of the air) that they were running constantly. Even with the almost continual running of our air conditioners, we had over 60% humidity in our home (our units now keep the humidity at about 37-41% depending on the day). These air conditioners were designed to be 10 year units (the builder put them in), and they were 12 years old at the time. I'd say their useful life had ended.
As for the washer/dryer, my old units were "high efficiency" kind, but my washer leaves "mystery stains" on my clothes periodically, and was WAY to loud for the location in my home. Plus, the six year-old high efficiency washer cannot compare to the ones they have now. However, my mom and stepdad, who live on social security were THRILLED to have my old washer and dryer to replace theirs, which are over 20 years old (they are the old "coppertone" ones), are HUGE energy/water users and are certainly long past their useful life. They are going to try to get my washer repaired (I wished them luck, I had three different repairmen out who were stumped). I knew that finding a good home for my washer/dryer would not be a problem. When we got rid of our last set, we gave it to a newlywed couple who did not have a washer/dryer. A friend of mine gave hers to a battered women's shelter who always needs them to help single moms get situated in apartments after a bad relationship has ended.
If appliances are still good, it is easy to find people who would benefit from them. As for the "wet blanket" part, I wouldn't say that....but, I would say "cynical". Of course when you switch to more energy-efficient appliances, you will make waste. However, that is also true of things like cars as well. But, would it be better for someone to keep their '77 Dodge K car (which always seemed to have emissions issues at testing time), or switch to a more environmentally friendly car? I mean, one creates a pile of scrap metal if you dump it, but creates a lot of pollution if you keep it.

Besides, a '77 Dodge K car was never meant to go 30 years. Keeping high energy consumption appliances post their useful life is never good.
If that means that somewhere a washer/dryer is made into scrap metal, that is a separate issue that needs to be addressed (kind of like the landfill issue). I know that the UK is working on such issues right now (I'm not sure about the US). From what I understand, old appliances are taken to areas where they can be disassembled. What is recyclable is recycled, and what is not is thrown in a landfill. The UK is actually considering adding a "disposal fee" to everyone who replaces an appliance and needs the other one carried off. This fee would cover the full expense of disassembling and recycling the components of the appliance. We didn't allow the installers to carry off our new washer/dryer, but I did ask about what happened to our old air units. The installer said part of our cost was to pay to have them carried off, and that fee was used to have them disassembled and recycle what they could. It sounds much like the UK.
When people are being told to change out their appliances, cars, etc. to more efficient ones, I agree that recycling DOES need to make some improvements. It sounds like a industry that might BOOM in a green technology society. However, what REALLY stands out in my head, is people who trade in an old car to get one that is just as fuel INefficient, and creates just as many greenhouse gases as the one they had.
