Not necessarily! We had the same problem a few years ago. The lineman traced to problem to a high resistance connection in the splice on one hot side at the transformer.
It had been there since the transformer was installed in 1981. Just gotten worse over the years. The previous owner fought problems with the heat pump and well pump for years.
The lineman replaced the splice crimp connector and everything checks out properly.
