When you’re shopping around for a new furnace, you might start to develop a new vocabulary. There’s the AFUE—Annual Fuel Utilization Efficiency—that helps you determine the efficiency of your new system. And another set of terms you may see used often are as follows: “one-stage,” “two-stage,” and “modulating” furnace.
You might notice that modulating and two-stage furnaces receive a higher rating for efficiency and performance (or simply find that the price for these units is higher). Wondering why this is? Does a two-stage or modulating furnace really make that much of a difference? Find out in today’s guide to these powerful systems.

This year, don’t waste your time making repairs for your home furnace in the middle of winter, when you need it most. You might be surprised to hear that a large portion of the problems we see with furnaces in the colder season are largely preventable. Furnace repairs are frustrating, and in some cases, they are also dangerous. We want to help you avoid them at all costs.
