Heating and cooling are essential processes that help maintain comfortable indoor temperatures. Heating systems, like furnaces and heat pumps, warm up spaces during cold weather by using energy sources such as gas, electricity, or oil. These systems distribute warm air or hot water throughout a building, ensuring everyone stays cozy. On the other hand, cooling systems, such as air conditioners and fans, help lower indoor temperatures during hot weather. They work by removing heat and humidity from the air, making the environment more pleasant. Both heating and cooling systems are crucial for creating a comfortable living and working space year-round.
