Customer called for air-conditioning not functioning. Upon inspection I found the heat pump shut down on a low pressure switch. Went to check the operating pressures and found the system with a 25 psi suction and a 3 psi liquid. This turns out to be a major leak in the system. System holds a factory charge of over 12lbs 410A refrigerant. We would need to return recover the rest of the refrigerant that’s in the system and do a high-pressure nitrogen leak investigation. Once we find the leak we can then move onto the next phase for the system to get it back working properly. Current evaporator coil is nine years old and the condenser is 13 years old. The office will follow up on Monday so that we may make the appointment to move forward with the leak search. Customer has home warranty from America’s preferred and customer will be coordinating with the home warranty to see what they cover. System is not operating at this time.
