Home > Innovative Modulating Gas Furnaces: Affinity 33"
Innovation puts one of the industry’s highest ratings in a smaller 33-inch package.
Introducing a modulating design that feels right at home.


A furnace that fits every customer.

We’ve taken the industry-leading features of our Affinity™ and Latitude™ gas furnaces and reduced them to just 33 inches high. And with a precise modulating rate at .65% increments, our Affinity™ modulating furnaces keep your customers consistently at their ideal temperature. We call it improving on an already big idea. You’ll call it perfect for those tighter applications. We’ve also shortened your installation and maintenance time by using modular door panels to simplify airflow conversion and added a slide out blower motor for easier access.
