Adequate for a mid-century house as originally built. Add central air, an electric dryer, a hot tub or a car charger and it is not. A load calculation is inexpensive and settles the question before you buy the appliance.

This is most common in homes built roughly 1940 to 1980. Post-war and mid-century — copper supply, aging cast iron stacks, 60 to 100 amp panels, first-generation central air.

You can handle this one yourself. No call needed.
