A 1983 builder sized the panel for 1983 loads: usually 100 to 150 amps, enough for the range, the dryer and central air. Then the loads changed. A heat pump, a hot tub and a Level 2 EV charger each want a big breaker of their own. Once two of them show up, the slots run out.
The signs repeat from call to call: no empty spaces on the panel cover, a tandem breaker squeezed in where one belongs, lights that dim when the compressor starts. None of that means the copper wiring is bad. The service needs more capacity, and a 200-amp upgrade solves it in one visit.
Storms count too. Ida's remnants flooded parts of Montgomery County in September 2021 and caused widespread outages. A standby generator with a transfer switch keeps the heat pump running next time.
