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.
