I am not profession to be an expert. Fifty years ago I worked on all home appliances including water heaters and window air conditioners.
At that time knew a good bit on the central A/C units but never worked on one.
Since then so many brands have disappeared. Some were bought and some just died.
It was sad when GE was bought by a Chianese company. Right sure that leaves Whirlpool as the only major US appliance company.
As was mentioned a gas range normally last a long time regardless the brand. It was and is still my impression standard ranges, less options more so last a long time unless abused. Such as spraying clears into electronic controls. Freezers, water heaters also are normally see long lives. Now stay away from the really cheap with any appliance.
It was always my opinion Whirlpool was over all the best brand. They are not all US built machines. Not sure all are but their front end loader washers and dryer were built in Germany. Made sense they had them years before were popular in the US. Over the years hate to guess all the brands Whirlpool has bought. Maytag, Amana, Roper, Kitchen Aid. Think right on those and right sure there are others.
We have had three Whirlpool appliances that disappointed us, (housekeeping 50 years) a microwave maybe 10 years, double oven, also 10 or few more years, and a dishwasher say 8 years. Not bad.
My best recommendation is to look at reviews and read them carefully. Some of the reviews are so "dumb". Oh I gave it 5 stars and cannot wait till I get it. Or 1 star because it was dented. Two stars I do reach are the 1 and 5 stars. Don't miss the sales person, of course they will try to sell the brands they have but most will be honest between the brands they do sell.
