Think of your furnace as the heart of your home. In the winter, it’s essential to radiate warmth. During the summer, it plays a vital role in moving refreshing, conditioned air from your cooling system. And all year long, your furnace could provide constant air circulation to keep you more comfortable. Not only that, but many of our furnaces do it all, so efficiently, your own heart might skip a beat when you see how low your utility bill is.
