Heating and AC systems are essential components of any home or business. They provide the necessary climate control to keep a building comfortable and safe. Heating and AC systems work together to regulate the temperature and humidity levels inside a building. The heating system works by drawing air from outside the building and using a furnace to heat it. The air is then circulated throughout the building using ducts or vents. The AC system works by drawing in warm air from outside the building and using a compressor to cool it. The cooled air is then circulated throughout the building using ducts or vents. Heating and AC systems are essential for maintaining a comfortable and safe environment in any building. They also help to reduce energy costs by ensuring that the temperature and humidity levels are maintained at the desired levels.
