Great service under warrantee

Called Dibiase in the morning - Kurt and crew were here to fix leak and were finished PDQ with report and invoice ($0) issued by 2.15pm. Kurt took the time to explain the issue and what corrective action they had taken. Can't ask for better.

Installed new trunk and flex in the basement coming off the first floor have unit. 1 10x10 trunk going behind the units feeding the left side of the basement and a 10x8 trunk feeding the right side of the basement. 2 zone damper installed on main supply feed to cut off upstairs from basement and 2 zone dampers on the trunks we install to cut off basement. Installed new zone board and wired it into the existing unit and will be ready for thermostat when basement project is finished. Under the steps need to be dry walled so we Disconnected the 10 inch supply running under the stairs just enough for the drywallers to remove it but know where it needs to be when reinstalled. I also marked out where the hard pipe will be coming through the wall into the utility room to connect to the new supply trunk. Replaced 10 inch hard pipe running under the stairs with flex duct and reconnected

Heat Tune Up for 80K BTU natural gas furnace. Replaced filter. Cleaned flame sensor. Checked hot surface ignitor ohms and watched for hotspots during start up. Checked burners and heat exchanger. Measured gas pressure. Measured temperature rise. Checked thermostat operation and all wiring. Opened bypass duct on humidifier, checked pad and tested operation. Combustion test: passed. Checked all electric motors and components. 10 uF blower capacitor reading 9.21 uF. Strongly recommend replacement. ST-5 Expansion tank for hot water heater is internally compromised. Water heater Relief valve is opening from time to time. Strongly recommend replacing expansion tank. Furnace is operating well at the time of this maintenance but the weak capacitor could fail causing a no heat/ no cooling situation. Relief valve of hot water heater will continue to open periodically if expansion tank is not replaced I attempted to call Jay to discuss recommended work but He did not respond. Left emailed

Air handler fuse was blowing during calls for cooling. Found thermostat was wired wrong. Rewired blue conductor to common and orange conductor to “B”. Made call for cooling while leaving one low volt lead on outdoor contactor off, manually placed lead back on contactor and outdoor control board went into delay. Condemned contactor. Replaced contactor with one provided by AtWater. Tested system in heat and cooling. System is operating well at the time of this service.

No cooling. Keewon and Troy have been resetting breakers every 3 weeks as it has been randomly shutting off to allow this system to operate. Checked for 24V between Common and Y at outdoor. O Volts. Checked outdoor 40/5 Capacitor ok. Checked for open low and hi pressure cut off switches at outdoor control board. There are no open switches. Blower motor was running at fan only speed. Visual inspection of indoor control board shows extreme corrosion of board itself. Reset breakers cycled heat and cooling at thermostat. System ran well. Contacted Troy who approved replacing board with board from hallway system. Board on second floor hallway AirHandler was also fried and line voltage leads were disconnected. We took board from 3rd floor hallway air handler. During final conversation with Troy I explained that both the second floor hallway system and the third floor system hallway system are without indoor control boards. Troy will buy and install control boards for these air handlers
