The answer to 'types of HVAC system' is that there are several common types of HVAC (Heating, Ventilation, and Air Conditioning) systems used in homes. The most common types are central air conditioners, heat pumps, furnaces, and boilers. Each type has its own advantages and is suited for different home sizes, climates, and energy efficiency requirements.
Central air conditioners are the most popular type of HVAC system, providing both cooling and heating. They use refrigerant to cool the air and a furnace or heat pump to provide heating. Heat pumps are a type of HVAC system that can both heat and cool a home by transferring heat rather than generating it. Furnaces use natural gas, propane, or electricity to generate heat, while boilers use hot water or steam to heat the home. The choice of HVAC system depends on factors like home size, climate, energy costs, and personal preferences.
