The Carrier Infinity system represents the pinnacle of residential HVAC technology. Unlike traditional furnaces and air conditioners that simply turn on and off, the Infinity system communicates. It is a marvel of engineering that adjusts airflow, humidity, and temperature with surgical precision.
Most HVAC systems installed in the last 50 years are "conventional" or "non-communicating." They rely on a basic 24-volt control circuit. When the thermostat calls for heat, it sends a 24V signal down the White wire to the furnace. The furnace turns on. Simple.
