WO-TNFR303160 upon my arrival in Flatonia, I found that the plenum had come part from the A/C unit, the drain line was backing up, and the system is dirty. System is slightly low on refrigerant also. Recommend HK2 repairs he choose HK2C . Connected duct work and blow the drain line we need to return recommended safety switch on the upstairs system he was not interested on that repair at this time. , to do a cleaning on the downstairs system, need spray 35/5 cap, float switch duct sealant. We also need to adjust the charge on both systems. Charge 125 per pound.
