What is a Furnace or Air Conditioning Probe?

Whether it's a furnace, air conditioner or packaged unit, a probe’s function in an HVAC system is to measure temperatures within the air conditioner and in the space outside of the unit (i.e. the room that it’s in). This information gathered by the probe or sensor is then utilized throughout the system to help maintain regular operation and optimal temperatures.
