I have been concerned our electric bill is higher because of aging Maytag washer dryer of 20+ years of age. At times our dryer doesn't seem to heat ,just tumble. It has been working good lately. I like Speed Queens longevity but just heard of them. I don't have money to waste which is why I ask if I should replace these for newer maybe more efficient ones??? or stay with them till one dies. I consider this as I don't want to have to buy a HE in the future.
