Today I discovered that the Lennox unit was not cooling well. There was a leak found on the second compressor circuit’s service valve shrader. This shrader valve is proprietary to Lennox. I spoke with Jake about this and received approval to recharge and cap the service valve. It was also discussed that it is always possible that there may be another leak in the system. The system was recharged and monitored and temperatures were gathered. Due to the high humidity load and small area it serves as a restaurant (multiple door openings) I recommended that the unit not be turned up over the night when no one is there as the run time will help to remove humidity. This unit does have a belt that is loosening and we have in the past communicated that to Jake. It was functioning today. Thank you.
