Upon my arrival I checked into the customers concerns with the systems leaking water. After stress testing both units with water several times I found the condensate pumps are doing their job and pumping water from the system. While I was checking the units I found them to be blowing warm air. I checked the systems pressure and found it low on refrigerant. I spoke to with the customer about my concerns and went over the different leak searches that could be performed. Customer chose to have the UV leak dye performed. I installed UV leak dye into the system then added 2.5 pounds of R410a back to the system. System is now showing ok pressures with an ok temp split. This will allow the unit to run enough so we can return to perform the leak search. Recommend scheduling 1-2 weeks from today.
