There is no one definitive answer to this question since it largely depends on a number of factors, such as the state of the economy, global market trends, etc. However, we can take a look at some data and make an informed guess.
According to The Balance, appliance prices have been on the rise in recent years due to a combination of factors including tariffs, increased demand, and raw material costs. After reaching a peak in 2018, prices have begun to level off somewhat but are still higher than they were a few years ago.
It's difficult to say definitively whether or not prices will continue to rise or if they will start to fall in the next few years. However, if we look at historical trends and current economic conditions, it's possible that prices could begin to drop in 2022 or 2023. Of course, this is only speculation and anything could happen between now and then that could impact prices.
