Very detailed. Much appreciated
Performed ESA, tech found leak inside evaporator coil in the downstairs unit. Tech took pictures of downstairs system including dual furnace and condenser. Video of leak should be uploaded as well as pictures. Homeowner would like to have field supervisor to give him a call to see what his best options are. Homeowner also extended PSA.
Tech found thermostat reading 70 with actual temp at 75. Tech recommends replacing thermostat. Tech replaced thermostat and insulated the hole behind the thermostat that was bringing in cold air. Thermostat is now showing the correct temperature. Tech tested in heat and cool modes and found AC not working and heat only working in Emergency Heat due to no high voltage at the condenser. Fuses were good, but disconnect not receiving voltage. Tech found the main breaker tripped. Tech turned it back on and found unit running, but could hear breaker popping and tech shut it back off. Tech recommended calling an electrician to determine if the breaker needs to be replaced. 3 pole commercial breaker. Manager has been notified.
Tested both zones individually for heat for 20-25 minutes each, both damper motors opened and closed as they should, inspected the burners, flame sensor and igniter for proper operation. Found an insect blocking the bottom section of the burner, removed the insect and cleaned the burner and flame sensor. Checked gas pressure and found it to be slightly high for what the manufacturer recommends, turned down the pressure from 3.8inWc to 3.5inWc. Damper motor for upstairs made a clicking noise once when the zone was tested, tech advised to monitor the upstairs airflow. Tested the system upon departure and both thermostats were satisfied on set point. Tech recommended our ESA(maintenance agreement plan) and decided to invest in yearly PSA. Bljones0529@gmail.com
