You should be able to go to appliance repair shops and get the better stuff. Air Conditioning and Refridgeration places as well. You will need your EPA permit for the freon's but not for the other stuff.
I'll give you an example.
My two air conditioning units, would just for some reason EAT capicators, every few years im replacing them. The American caps, would just ground out. grum grum grum, the motor gets hot then eventually trips out, the house heats up, thermostat may or may not flash a fault... either way I go outside and trouble shoot, go ooh, bad cap on the compressor, lets replace it. good for 3 more years.
Well the American one was out so I went with the chineese one. when IT died, on BOTH units, so it was a PRODUCT PROBLEM.... the capicator actually melted down, I mean it was like a friggin ceramic lava poured out the top of this sob. UNFORTUNATELY the control board is right under the capacitor so that lava poured right on top of the control board and took that out too. So now it's not only an extra 23 dollars for a new cap but 400 dollars for a new control board. When the first one went, I went to the other unit and actually moved the capicator so it was not over the control board, and sure enough a few months later, it went too and did the SAME THING. China does not have Underwriters Laboratories or the equivalent that they HAVE to abide by... one of the reasons their stuff is cheaper. but when it does go... it can go in a very BAD way.
I can tell you a story of a small refrigerator compressor, chineese s41t, that as it turned out, did not have the internal thermal trip on it like US models do, hence why it was cheap at Lowes.... compressor froze but did not trip out, and when it did finally blow out the back of the unit, filled the house with toxic smoke. (Think the freon and burned motor windings and oil at several hundred degrees or so) Looking back through my electric logs, it took HOURS and HOURS for this thing to finally reach this failure point.
MY point being, an American unit with the extra safety stuff, would have taken itself offline and eventually shut itself down for good.
The Japaneese cars, yes, those things will last forEVER as well. VERY high quality. The Japaneese culture as a general, embrace quality, when you pay for their top end stuff, you truly ARE getting TOP END STUFF. Their cars are no different, the parts are inexpensive but the things last about forever unless you wreck them.
