I do not understand how central furnace heats up a whole home

So she consulted a local A/C representative that recommended a more modern and efficient gas furnace/heater installation

I grew up in a small farm home with no AC! In fact I never knew much about it until I visited an aunt in the city and I heard her complaining about the poor weather conditions control in her residing area, but she lived in a bungalow with 4 kitchens and a stretched out garage where she kept most of her old household appliances. She’s a hoarder, and among her things in the garage are a traditional cooking stove, cooking table top, a 2-face commercial air conditioner component and a low powered heater, these were from her corporation that closed down a few ago after she couldn’t meet the local health regulations in her eatery, and a local service provider who mostly deals with commercial Heating & A/C for sale had bought most of her corporation equipment. So back to her home that had several units of independent ductless mini cut spread across most rooms. I couldn’t believe she used to rely on a central AC system to hot or heat the whole house. I understand it was a lot of ductwork all around the home and as the home she built 30 years old aged, A/C service was becoming overpriced. So she consulted a local A/C representative that recommended a more modern and efficient gas furnace/heater installation. These new units demand infrequent A/C repair and heat pump service. I liked that specialists often offer useful energy saving tips but the ultimate advice was to google more about air conditioner. It was fine to learn how attics vents play a pivotal work in heating and cooling bungalows by relying on the help of a dehumidifier, something that you can achieve by buying a furnace for sale.
