Thanks again Cory for this important piece of history.
This was a huge breakthrough when they finally started labeling appliances for the energy they were likely to use, before this manufacturers got away with all kinds of nonsense telling you this that's more efficient.
The interesting thing is that the higher efficiency appliances in this era generally lasted much longer than the ones that burned more energy.
That 17.2 ft.³ Whirlpool refrigerator they featured they had replaced all the fiberglass insulation in the body and foamed the whole thing in that refrigerator was so efficient over the long haul that they lasted so much longer. The compressor didn’t have to work hard. There wasn’t near as much heat underneath. It was a really great refrigerator even the higher efficiency evaporator fan motor and condenser did not run as hot and did not fail nearly as often as the regular models, we sold a lot of those refrigerators and they worked great, I still see some of these as 2nd refs in peoples basements going strong while the power hog frost-free models are pretty much long gone.
The first thing I did when I bought my house in 1977 was installed central air conditioning. I bought the top-of-the-line whirlpool central air conditioner with a 9.6 E ER which today translates to about a 13 seer. I paid $675 for the coil the lines in the outdoor unit and installed it myself. A neighbor of mine across the street had had a gas air-conditioning system which failed and he was replacing the system himself. I suggested I could get him one of these high-efficiency whirlpool’s but he said no that’s too much money. He bought a Tappan system for a little over $500 and installed it himself.
He had to replace that air-conditioning system two more times over the next 30 years that he lived there. Meanwhile, my whirlpool was running silently along. You couldn’t even hear the thing it was so efficient outside and it lasted 42 years probably saving me well more than $1000 in electricity.
Certainly, every case is not the same, but today, the highest efficiency appliances are generally gonna be more reliable than the least efficient ones for the many of the same reasons.
The good news is the energy star program was so effective that virtually all refrigerators are quite efficient today, the same thing with central air-conditioning with the minimum of energy standards. It’s hard to buy one that’s really bad, but there are still better choices in many cases so this is still an important program.
Unfortunately in the US it never covered gas and electric range efficiency and as a result manufactures took advantage of this loophole and ranges bought today [almost without exception ] use more energy than similar models did in 1980.
