Having an air conditioner but no heater in your home is not necessarily weird or uncommon, depending on your geographical location and climate. The need for heating or cooling appliances in a home is primarily influenced by the climate of the region where the home is located.
In regions with hot summers and mild winters, such as many tropical or subtropical areas, people often prioritize cooling solutions like air conditioners to stay comfortable during the hot months. Heating may be of secondary importance since the winters are generally not severe and can be managed with extra layers of clothing or other temporary heating options like space heaters.
On the other hand, in colder climates with harsh winters, having a heating system becomes a necessity for maintaining a comfortable indoor temperature. Air conditioning might be less crucial or required only during the warmer months.
Additionally, some homes in moderate climates may rely on alternative heating sources, such as radiators, wood-burning stoves, or even geothermal heating, rather than a traditional central heating system.
Ultimately, the decision to have an air conditioner without a heater or vice versa depends on the specific needs and preferences of the homeowner, as well as the climate they live in. As long as the home's occupants can stay comfortable throughout the year, the combination of cooling and heating appliances can vary from one home to another.
