Performed the cooling evaluation in Rosanky on both system. System number 2 the Reme halo was not coming on. I found that the voltage conversion system was faulted. I replaced the voltage conversion system under the warranty from when the Reme halo was installed since it was the one that came with the Reme halo. Turned the system on and found it working properly. I found that both systems are low on refrigerant indicating a leak on the system. I spoke with the customers about my findings and recommended having a comfort specialist come out and quote a system replacement on both units. They would like an appointment set up for the comfort specialist to come out and go over the quotes. When the comfort specialist comes out they are going to ask about having the 2 systems combined into 1.
