Our expert installers will evaluate your home and recommend a new furnace that is properly sized—large enough to meet all your needs, but not so big that you overspend on equipment and energy bills. In many cases, we suggest an ultra-high efficiency modulating system—a furnace that’s up to 97.4 percent efficient. Depending on the manufacturer, it may come with a 10- to 12-year parts warranty and a lifetime heat exchanger guarantee. Of course, there are several efficient options to meet your preferences and budget, and we also install boilers and in-floor radiant heat for custom comfort.
