9/15/26. Found water leaking onto drop ceiling from recently installed trane a/c and gas furnace horizontal. Took apart coil door and poured water in drain pan to test operation, drain pan drained out completely. Motor on system is an x-13 blower motor with speed tapping. Air flow is set on tap 8 and outside a/c is a 5 ton. Speed tapping 7 drops down to around 1400 cfm which is to low. Need to see if trane makes a splash guard for this coil and need to install it on both units that were recently installed and get back to the church about splash guards.

Luis 9-15-26 Performed gas heat inspection on trane 90% heater installed 10 months ago. Check all components ok electrical low and high voltage.

Luis 9-12-26 Customer called in for no cooling, installation was done yesterday. Found several issues with system. Water sensor kept going off. Leak from furnace trap adapter. We will need to come back with oem part to fix this (I temporarily added silicone). Water sensor was making buzzing sound when tested I corrected wiring, I also added y1 to y1 I’m heater control module, I tested ac ok. We will need to return visit to replace drain fitting. Recall on installation. I also adjusted air flow to 1200 cfm. Control board does not have a tap for 3.5 tons. I used 3 ton tap and 350 per ton. Around 340 per ton 1200 cfm. I did this to compensate for high static pressure. Customer also keeps some of the vents closed on first floor. Total static pressure 1.25 wc. I advised customer to open up vents. With vents open drops to around 1 wc.

Replaced A2L mitigation sensor and control board. Also double checked continuity through each of the wires of sensor to verify integrity of sensor wires. Tested system afterwards. Wrapped sensor harness with electrical tape to prevent any water from getting in. Mitigation board green LED steady flash: Good Checked temperature split 18.5° Good System operating well at this time

Luis 9-11-26 Return visit to troubleshoot unit, we were out here for no cooling yesterday and Customer called back in for no cooling again. Attic system two zone system thermostat. Found indoor coil and outdoor line frozen. I troubleshoot indoor unit check both thermostats zoning operation found both zone dampers acting up and not opening correctly. At this time I remove wires from dampers (force open) so customer has cooling. We will provide an estimate to replace both zone dampers. Both thermostats are set to off and fan on for at least until 6 o’clock tonight then customer can resume normal cooling operation. No service charge for today visit Emailed estimate for repairs customer was not home during the visit. Only wife was present. I talked to homeowner through the phone and explain him the situation. Give him a price. he decided that he will call the office Monday morning or sometime next week.
