This is from RVP's Technical. So, I AM NOT WRONG. I just use the Temp diff to document for the customer. I take an AMP reading with temp correction for the correct performance. Doug
An ideal cooling system should give you an output temperature range of 16 to 22 degrees lower than the temperature taken in at the filter. Humidity is a significant determining factor in this temperature difference.
You can test the temperature difference by taking a reading at your filter and the first register where air is leaving the system. Please use the same thermometer at each location.
