A heating system is a setup designed to warm up a building, making it comfortable during cold weather. It can use various energy sources, such as natural gas, electricity, or oil, to generate heat. Common types of heating systems include furnaces, boilers, and heat pumps. These systems distribute warm air or water throughout the space, ensuring that every room reaches a cozy temperature. Regular maintenance of a heating system is essential for efficiency and safety. Homeowners should check filters, inspect ducts, and schedule professional servicing to prevent breakdowns. A well-functioning heating system not only keeps you warm but also helps save on energy costs.
