DCM1 complete; Heat; (1) F20221 replaced. System is fully functional. All components are operating within manufacturer specifications. Refrigerant pressures and temperatures are appropriate for indoor and outdoor conditions. Heat checklist atrached
Replaced board tested operation everything is operating properly at this time.
Removed old furnace and installed new Rheem variable speed 2 stage gas furnace. Installed new return plenum with 16x25x4 filter, new emergency drain pan, new pan safety switch, and new thermostat. System did not start up due to no high voltage going through control board. Need to verify control board is bad, replace, and test system operations.
Signed proposal for new gas furnace
DCM2 complete; Heat; (2) F16251 replaced, unable to complete heat maintenance Upstairs system is fully functional. All components are operating within manufacturer specifications. Gas pressure and heat rise are within designed parameters. Downstairs system identified as have a faulty control board. System progresses through cycle of operation but fails to energize gas valve, no 24v received from board to gas valve. Inducer motor bearings/fan are making noise sounds like bearings are beginning to fail. Pulled inducer motor and checked for obstructions in the fan and flue with none found. Homeowner request comfort advisor for quote to replace furnace. Homeowner is fine with Wed from 1-2pm Estimates for repairs included-
AHU #6 condensate pump vinyl drain line has split over rental unit #224. The existing vinyl plastic was a legacy size that is no longer used. Installed and secured new vinyl tubing, 3/4 in PVC and assorted couplings. System drains properly and is easily accessible for future repairs. Tested system and programmed thermostat to hold scheduled temperature window.
Replaced both thermostats on AHU #11 and #4. Tested systems, functions as designed. Programmed thermostats to Auto change-over and maintain a temperature window of Heat at 68* and Cool at 76* Unable to complete drain for #6, unable to access unit #222 to install new drain line. Will have to return
Adjusted all possible thermostats to auto Systems #4 and #11 : have old mercury thermostats and have no auto function availability System #6 : condensate pump vinyl tubing has separated/torn apart. Vinyl tubing coming from the unit is a different diameter than the new style vinyl tubing. Recommend doing a drain repair that is similar to the repair done on unit # 9 ( invoice date 7 Jun 23). Will need to access storage unit # 222 to complete repair.
Set all thermostats to Heat, set at 65*
Warranty call for failed TXV Replaced existing TXV and filter dryer. Pressure tested system, removed all moisture and non condensable gases from system, achieved a vacuum of 387. Tested system. Diagnostics photo attached
