I arrived for a no cool call. I spoke with the homeowner and four company has recently replaced the compressor. I inspected the system and found the system severely overcharged. I removed refegerant from the system to get the subcooling downto 4 deg subcooling. When I tried to add more reference the compressor would over amp up to 38 amps and trip the breaker. We talked about options on replacing the system. I will follow up on Monday if the system dose not fail beforehand that time.
