The answer to 'difference between air conditioner and' is that an air conditioner and a heater are two distinct HVAC (Heating, Ventilation, and Air Conditioning) systems that serve different purposes. An air conditioner is designed to cool and dehumidify the air in a home, while a heater is used to warm the air and provide heat.
Air conditioners work by absorbing heat from the indoor air and transferring it outside, effectively cooling the indoor environment. Heaters, on the other hand, generate heat through various means, such as electricity, natural gas, or propane, and distribute that heat throughout the home. The choice between an air conditioner and a heater depends on the climate, the specific needs of the homeowner, and the overall energy efficiency of the system.
