Eval- Geo thermal heat pump has been going through issues, last major repair through HW were the water pumps, they were recently replaced, customer informed me that they added “Leak Stop” and that they didn’t find the leak, only that they added 407C and charged it on Thursday of last week but when I connected my gauges, nothing shot out, 0 psi on both sides Informed customer that the Low Pressure cutoff was tripped and not allowing voltage to go through to entire system Customer ultimately would like a system replacement quote for both geothermal heat pumps to change to furnaces Comfort Advisor is scheduled for today 3-5 pm Thank you for choosing Comfort Experts, have a great day
