PERFORMED PTU ON (1) TRANE SPLIT HEAT PUMP. FOUND CONDENSATION WITHN BLOWER COMPARTMENT CAUSING SMALL AMOUNT OF LEAKAGE INTO 1ST FLOOR BATHROOM CEILING. CUSTOMER STATED PREVIOUS TENANTS HAD TEMPERATURE SET LOW AT 67. FOUND EVAPORATOR COIL DRIPPING MIDWAY AND SUCTION PRESSURE/COIL TEMP SLIGHTLY LOW DUE TO LACK OF AIRFLOW. MOVED BLOWER SPEED FROM LOW TO MEDIUM SPEED. VERIFIED NO CRACKS WITHIN PAN, COIL IS CLEAN, AND PROPER DRAINAGE. PRESSURES WELL WITHIN SPECS. EVAPORATOR COIL IS NO LONGER DRIPPING. INVESTED IN ESA (1) SYSTEM.
Tech performed ESA on split zone system. Customer changes his own filters. Tech left spare filters. Tech found 45/7.5uf dual capacitor reading 13% weak on FAN side. Confirmed Trane warranty valid on outdoor unit until 2030. Quoted warranty capacitor price. Customer approved repair. Customer expressed concern about number of repairs on a 4 year old system and also wondered if system is undersized. Tech suspects system size is roughly correct. System appears to be operating properly. Customer can call with any specific questions or concerns.
REPLACED ZONE CONTROL BOARD/INSTALLED SURGE PROTECTOR. CYCLED SYSTEM WITH NO CHALLENGES. CALL TO SCHEDULE MAINTENANCE.
FOUND SYSTEM RUNNING HEAT PUMP AND BLOWER CONSTANTLY DUE TO FAILED ZONE CONTROL BOARD. CONTROL BOARD IS RECEIVING 24V POWER WITH NO DISPLAY PRESENT. NO CALL FOR HEAT PRESENT FROM EITHER THERMOSTAT, BUT 24V PRESENT AT EQUIPMENT TERMINALS Y AND G. NEED TO ORDER AND RETURN TO REPLACE ZONE CONTROL BOARD/INSTALL SURGE PROTECTOR. NO BYPASSING PERFORMED PER REQUEST. INVESTED IN ESA (1) SYSTEM. SCHEDULE AFTER REPAIRS ARE MADE.
Filter count is six 20*20*1 filters. Not four. Did CMA full service on 2 split systems. Air handler 2 (serial 1B2V) (7 years old) goes to newly replaced outdoor unit 2. Tech found heat mode head pressure on new outdoor unit 2 near 640 psi on new Trane condenser. Compressor is overamping. Switched to cooling mode and found system is overcharged. Joy reports we did not install this outdoor unit. Tech called Laine P and quoted $367.49 to recover 1-3 lbs of refrigerant. She declined. Needs to talk to her boss. Tech let her know that we will need to charge a service call to return to the beach if she wants us to correct refrigerant charge at a later time. Both systems are heating and cooling.
Tech washed and serviced units Bill out for renewal
Tech found 2015 model Trane split system (last 4 of outdoor unit R34F) not cooling due to a failed 7.5uf outdoor fan capacitor. Tech replaced it for testing and found outdoor fan back amping correctly and system cooling correctly. TXV was replaced and leak repaired on this system in September last year. System is back cooling normally. Tech found 2014 model Trane split system (last 4 of outdoor unit RG4F) not cooling due to being nearly devoid of 9 lbs of R410a. Had about 80 psi of standing pressure, but low pressure switch was stuck open. High pressure switch was closed. Tech bypassed low pressure switch to get system to start up for testing, but compressor made a grinding sound and did not start. Capacitor is within specs. Tech homed compressor, but it still will not start. Tech diagnosed failed low pressure switch, failed compressor, major refrigerant leak or leaks in system holding 10 lbs R410a. Outdoor unit is highly corroded. Tech recommends system replacement. Lanie approved c
