Curly,
I totally agree about the energy rating, especially on refrigerators. My current one required a new compressor, fortunately before going out of warranty. The repair guy said the companies are undersizing the compressor to get better energy ratings, but as such, the compressor wears out sooner because it has to run too much since it's too small.
Any of the pros at HVAC-TALK would probably tell you the opposite, oversized compressors cycle themselves to death. It's more the number of power cycles per hour than the running minutes per hour that matters.
My parents' Coldspot freezer, still running when retired last month, is one example. It had been running constantly (except for power failures, annual defrostings, and 6 relocations) since my brother broke the temperature knob off of it in 1959. Yes, it was worn, yes, it clattered horribly (not sure if the clatter was internal or from worn out mounts) upon restart after a power failure, but it was made to last and it did, and the fact that it only had a couple of hundred starts in the past 50 years probably added decades to its life.
