Packaged HYBRID HEAT dual fuel systems give you the comfort of gas heat and the efficiency of a heat pump in one efficient package. Select the desired indoor temperature on an Infinity™ Control or our special dual fuel thermostat and the system automatically switches to the most effective fuel source
for indoor comfort.

At Carrier, your comfort is our business. That's why we have one of the most extensive product research and development facilities in the world. Within each step of the development process, from the design phase to
finished products, we test each and every product to ensure its performance is up to our standards. Infinity 15 packaged HYBRID HEAT dual fuel systems are tested for applications up to 125 degrees. That's a full 10 degrees higher than industry standards. And, Carrier systems have one of the lowest failure rates in the industry.
