Most buildings in the US use warm air. This means the same ducts can be used for both heating and cooling. There will be a central gas (or less frequently, oil) furnace or a heat pump. I think that switch occurred in the 1950s. Older homes might have steam heat, or sometimes electric baseboard heaters.
- maxerickson 10y agoHot water is also pretty common. I guess more so in areas where cooling is less needed.
