How will my new furnace work differently from my old one?Modern furnaces are developed with a variety of innovative features older furnaces don’t have. Today’s heating systems provide more even heating and are better at controlling airflow. Although the air coming out of your vents may seem cooler than your old furnace, the airflow is much better and more efficient. Another bonus of modern furnaces is their ability to operate with other HVAC products as part of a high-efficiency whole home comfort system. When combined with a high-efficiency air conditioner, furnace blowers can more easily accommodate add-on cooling. Other innovations, such as Precise Comfort™ technology and variable speed motors, will help your furnace run more efficiently and quieter than ever.
