How can HVAC systems affect energy costs?

• A. They do not affect energy costs
• B. By reducing overall energy consumption when maintained
• C. By extending energy use only on weekends
• D. By primarily cooling water

Answer: (B)

HVAC systems have a significant influence on energy costs, especially when they are properly maintained. Proper maintenance can optimize system efficiency, which in turn reduces the overall energy consumption required for heating, cooling, and ventilation. When components like filters, coils, and ductwork are clean and functioning well, the system doesn’t have to work as hard to achieve the desired indoor temperature or air quality. This efficient operation contributes to lower energy bills because less electricity or fuel is consumed. In contrast, systems that are poorly maintained may become less efficient, leading to higher energy costs as they need to operate longer and consume more energy to reach the same comfort levels. Therefore, maintaining HVAC systems not only extends their lifespan but also provides considerable savings on energy expenses over time by ensuring they operate effectively and efficiently.
