Tech washed and serviced both sys and found no challenges at this time both sys are up and cooling with a delta t of 24 downstairs and upstairs delta t of 22. Return with 12x12x1 filter.

Took pictures of unit and filters for CMA

System #20, found a rupture on the recently brazed discharge line at the 90 degree section, circuit #2 is voided on R22. Tech removed the 90 degree copper section and replaced it with new copper. Pressure tested and used soap bubbles to assure no other leak was present, pulled a vacuum below 500 microns. Recharged the system with 80oz of R22 (costumer had R22 on site). Tested system in cooling, both compressors operated properly. Service warranty due to recent repair performed on the same system and same braze location.

Found the condenser fan motor wires damaged, the fan blades cut the wires. Tech received approval to repair the wires and secure them as well. Tested system in cooling afterwards and system started to cool, condenser fan motor is pulling 0.9 amps out of 1.10. Tech did inform the homeowner about the compressor checking out on the caution level, meaning that the insulation value inside the compressor is getting weak which will lead to compressor failure. surge protection was recommended and costumer stated that he would like to wait on having one installed for now, system back cooling.

Tech washed and serviced unit and found condensate line to have no insulation and caused condensation to form tech recommended adding insulation customer is not interested at this time. Customer extended psa via master card. Unit is up and cooling with a delta t of 22.

Tech checked blower speed at split system 3, found blower belt loose. Tightened belt, inside of duct is not insulated but is in conditioned space. Informed Craig of findings.

Upon arrival tech found mini split in office leaking water due to failed mini split condensate pump. Repair was suggested in the past and estimate was made. Customer would now like to have condensate pump ordered and replaced.

Upon arrival tech was informed system was not cooling. Inspected system and found condenser fan motor over amping at 3.33 amps and cutting off preventing system from operating correctly. Tech further inspected and found the tenant had attempted to replace dual run capacitor had wired the fan on herm and compressor on fan. Tech corrected the wiring issues and cooled the motor down with water. System came back on and began operating as normal. System is back operational at this time.

Tech assisted Michael and Sebastian. Used 4 lbs of R410a.

-Found front thermostat running on schedule with fan mode on at all times. Back thermostat running on schedule with fan mode on at occupied schedule setting. -Fan constantly running does not allow system to dehumidify the air. Without a break in fan operation, water collecting on evaporator coil(s) is continually recirculating back into air instead of draining through condensation drains. -Modified schedule on both thermostats to keep fan in auto mode at all times. Maintained customer entered schedule times and temperatures. Humidity levels should decrease significantly, thermostats should be monitored in coming days to verify no further challenges.

-Arrived to find condenser not operating even with call from thermostat. Observed contactor not transferring high voltage to compressor and outdoor fan when engaged by low voltage wiring or manually activated. -Found presence of fire ants behind contactor blades, not allowing power to transfer. Suggest replacement of 1 pole contactor. Cleaning of existing contactor may provide a short term solution, but typically once ant pheromones have been released at a location the problem will continue even after cleaning.

Emailed proposal to replace upstairs and downstairs system. Customer is getting other quotes.

Tech found compressor and fan not running due to a failed capacitor. Tech replaced capacitor and found normal operation. Tech recommended maintenance plan. Customer only wants unit repaired at this time. Normal pressures and 7.4 degrees subcooling calls for 8 +/- 3.

Techs replaced burnt thermostat and thermostat wire from package unit to indoor splice. System is now running normally.

Techs found leak in evaporator drain pan at the joint connecting to the drain line. Techs sealed drain pan with PVC glue and water tested to ensure no leaks were present. Adjusted pitch of drain line where it was improperly supported that was causing stagnating water. Advised customer that we will order a new drain pan to resolve issue permanently, tech quoted out $870 to replace with new drain pan. System is draining normally at this time. Customer informed tech he will call once he gets approval.

Upon arrival tech was informed system was blowing just not cooling. Inspected system and found dual run capacitor in condenser failed. Installed new 40/5 capacitor and system came back on. Checked pressures and were within range. System is back operational at this time.

Upon arrival tech found thermostat blank due to blown 5 amp blade fuse at air handler. Tech isolated all low voltage wiring and removed thermostat due to locate short. Found short within brown wire at outdoor unit thermostat wire which was not wired to anything. Wire was touching against metal panel causing a short when yellow circuit was energized with a cooling call. Tech removed wire and replaced fuse. System came on and started running. Tech let surgeon run for about 25 mins to assure there are no more shorts. System is back up and cooling. Install warranty.

Upon arrival tech found both aux pans at air handler 2 collecting collecting water due to clogged drain line. Tech removed trap and let all water drain out from primary pan. Tech took drain trap outside and washed thoroughly. Added 1” union after trap to do so. Purged nitrogen through remainder of drain line, vacuumed out both aux pans. System is back up and cooling as well as draining. Service warranty.

Drain line fix

Tech confirmed system is getting correct voltage and transformer is wired right. Compressor sounds very bad and running at high pressures with subcooling fluctuating.
