Service Trane Outdoor A/C Compressor and Air Handler - - PAGE 75.
August 9, 2022: The technician John
Barco and his trainee assistant came today to check the air conditioning system.
Here is his newly hired assistant observing the job today. He
noticed the internal AA batteries were showing low voltage on the
thermostat. I gave him two batteries I had with me.
John started with the current and voltage readings to the air handler dual
speed motor in the utility closet. The measurements were normal as the
house is very cool with the thermostat set at 77 degrees.
John is opening the cover to reveal the coolant pressure test points on
the outside unit which was replaced two years ago..
He is connecting his pressure measurement devices, one for each line going
to the indoor air handler. The measurement instruments send the results to
his tablet computer wirelessly. When all the work was complete I signed
the appropriate pages on the tablet when we were sitting at the kitchen table.
I made this photo of their truck to show you the details of their company
data phones and insurance (I presume).
Here is the business card for John Barco, the technician who did the air conditioner checkup testing.
