Furnaces

Think of your furnace as the heart of your home. In the winter, it’s essential to radiating 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.

Some folks are perfectly happy with a basic-functionality furnace and others are looking for all the comfort bells and energy whistles. The good news is, whether you live in North Dakota or South Carolina, we have a range of fuel-efficient furnaces so you can choose the ideal one for your home. And frankly, when it comes to efficiency, it doesn’t get much better than our Infinity® 98 modulating gas furnace with Greenspeed™ intelligence for unprecedented comfort and energy economy.
