The device includes means for measuring a temperature differential between ambient and vent temperatures of the air-conditioning system, where the means comprises at least two remote probes for measuring the ambient and vent temperatures, or a remote ambient probe for measuring ambient temperatures and an integral vent probe for measuring vent temperatures; and means for analyzing the temperature differential in order to give an indication of performance of the air-conditioning system.
1. A device for verifying a proper heat exchange and overall performance of an air-conditioning system, comprising:
a) a manually operated means for measuring a temperature differential between ambient and vent temperatures of the air-conditioning system, wherein said means comprises:
a probe for measuring the ambient temperature and at least one probe for measuring vent temperatures, wherein at least one of the probes is connected to a portable housing through a cable connection; and
b) a battery powered and manually controlled means housed in the portable housing for analyzing the temperature differential and giving a visual indication of performance of the air-conditioning system.
2. The device of claim 1 wherein a probe is integrated into the housing.
3. The device of claim 1 wherein the probe for measuring ambient temperature is integrated into the housing.
4. The device of claim 1 , wherein a temperature differential of greater than 25°πF. between the ambient and vent temperature is determinative of whether the air-conditioning system is properly functioning.
5. The device of claim 1 , further comprising means to automatically adjust the temperature differential for changing ambient temperatures using an algorithm, thereby changing a pass/fail indication point.
6. The device of claim 1 , further comprising an LCD display.
7. The device of claim 1 , further comprising at least one LED.
8. The device of claim 1 , wherein the visual display provides an indication of either a pass or fail diagnosis.
