When I arrived I found that the system faulted on a low pressure lock out several times during the hotter days. Today I tested the heat while it was very cool outside and the compressor would not ramp up due to the pressures being low. I leak searched and found it leaking from the indoor coil. I will order the parts and we can call and schedule when we get the parts in. The client has a 10 years parts and labor that will cover the repair.
