Estimate

I arrived to the customers home to look at his heat pump system not working. Found when running an AC mode it was low on charge. I had a 60° superheat and 0-1 sub cool. I left estimates for the customer to review for leak search , adding charge to the system and if the system did have a leak either in the indoor coil or the outdoor coil if under manufacture warranty, I left him pricing so he can see the cost. He is scheduled tomorrow with the company that put the system in for leak search I collected for $99 diagnostic for today paid by credit card.

I arrived for a no cooling for a new customer. The heat pump American standard system is 10 yrs old . The customer had told me he had a guy out here for a few times to add charge to the system, but he never thought he actually repaired it. I went and looked over the indoor unit first I replaced the customers air filter supplied by the customer I inspected his coil and his blower housing and the motor. The blower motor housing had some growth on it . I went to the outdoor unit I put my gauges on. I had decent equalization of my pressures and went and turned the system on the indoor but not the outdoor. I had a call from the thermostat for cooling, but I didn’t have 240 V for power I found the breaker was tripped. I reset the breaker, and you could hear the compressor trying to run but tripped out again. I did a test on the capacitor and the compressor itself and the compressor internals has failed shorted to ground Causing it to trip the breaker. I Mega ohmed My leads at the contactor a
