How will my new furnace work differently from my old one?Depending on how old your previous furnace was, you could experience a number of differences. Furnaces today are designed to give more even and efficient heating than ever before. Modern furnaces also better regulate temperature and air flow, moving more air over the heat exchanger than older furnaces. Additionally, new furnaces are designed to work with other high-efficiency HVAC products, such as air conditioners. The air conditioner blowers provide your heating system an extra bump so it can deliver cool air around your home efficiently. Special features like variable speed motors will also help lessen noise associated with operating your equipment and easily meet your family’s airflow needs.
