They were quick in coming out and the service was great. The gentleman was very efficient and took the time to explain everything.
Upon arrival I went to system and shut off power. Removed old 3 wire damper actuator and replaced with new 2 wire actuator, both Honeywell. Mounted actuator to damper and tightened set screw. Labeled open and close on damper because you canâ€™t see indicator very well. Returned power to system and ran heat. Checked operation of all dampers. Then called for zone 1 to be satisfied and actuator closed. Called for zone again and actuator opened. Then satisfied 2nd zone and 2nd floor actuator closed while both zone 1 actuators remained open. Satisfied system and dampers closed. Unit operating normal at this time.
Replace Maxitrol pressure regulator on Carrier Unit (Cheetah Room). Upon arrival I went to roof and found system locked out on ignition fault, no gas, regulator stuck again. Shut off power and replaced gas regulator with new one. Removed vent tubing from old regulator and installed onto new one. Opened up gas valve and verified no leaks. Found normal incoming pressure so I returned power to system and ran heat until system satisfied thermostat. Went back down to thermostat and increased temp. Tested unit again and checked parameters until thermostat satisfied. Unit operating normal at this time.
Sent picture of economizer model to Matt.
Upon arrival I was told that heat in Cheetah room wasnâ€™t working again and now the heat in Zebra room doesnâ€™t seem to be working either. During diagnostics I found Cheetah room unit faulted on ignition lockout. Found no incoming gas to system. Maxitrol regulator stuck. Tapped on the bottom a few times until pressure released. Restarted system and ran heat. Checked all parameters and found no additional problems. Then went to Zebra room unit and found heat running but incoming air temp 50 degrees. Found economizer opened 100% because of failed outdoor temp sensor. Removed Economizer plug and put jumper plug on system to bypass Economizer. Tested heat and checked operation. Found no additional problems. Quoting customer to replace Maxitrol gas regulator and Economizer outdoor temp sensor.
Unit #9 on the second tier serves the classrooms. I found the unit would operate when the thermostat said â€œheat onâ€ but the gas would turn off to th burners when the thermostat displayed â€œheat 2.â€ It is a single stage furnace but that should not have made a difference. However there was a black wire wired to the w2 terminal inside at the thermostat but no black wire used on the roof. I removed this wire from the w2 on the stat and jumped w1 and w2 together just to make sure w1 doesnâ€™t drop voltage. Customer also had a concern about the blower noise. I assured them that this was unrelated but went back on the roof and tensioned the belt. It makes no aberrant noises. Unit operating normal.
On arrival we found the cube water temperature coming in set to 30 degrees, we lower it 15 degrees and unit was operating normal.
Checked operations on humidifier and wiring . Everything was working properly . When one zone would call both dampers would be open . Found in programming of thermostat that it wasnâ€™t programmed for a 3 wire damper so it would drop out of voltage and open the damper back up after it dropped the call for heat . Changed the programming in stat and checked operations. After making adjustments I found that the round damper going to the addition is a three wire damper and now will not work with the changes . Called Alex and let him know . We need a 8â€ round 2 wire damper . For now I powered damper to be open all the time .
Upon arrival I spoke with customer and confirmed that I wasnâ€™t here to replace thermostat but to install Humidistat for humidifier operation. Went to unit and confirmed that series 3 cannot use humidity controlled communicating thermostat because it needs the AXB board. Customer already had daughter 24v board and geo was using ACC terminals to signal humidifier. Installed Humidistat onto return before Evap coil. Wired Humidistat to break R onlly when Blower is running for call for humidity. Tested and unit is operating normal. Office please send final email invoice after billing has been adjusted.
When we arrived we replaced motor but the new motor was defective ,went and got new motor ,tested it ,unit back on normal.
On arrival found indoor unit motor not operating ,need to replace motor .
Replaced thermostat and checked operations . Found that the 3 series unit does not have the capability to have the humidifier work through the commucating thermostat . The humidifier needs a separate stat located on the duct work to be able to function .
Unit that serves classroom 6 and 7 was making a humming noise. Found the belt was a little too tight . Readjusted pulley and checked system . System is operating properly
Completed heating maintenance on all systems .
Replaced filters on all RTUs . Need to come back to complete maintenance.

Case #439629 . Spoke with Dave from waterfurnace and we confirmed that the master stat isnâ€™t sending the call for humidity. Recommend replacing . Checked operations on humidifier and it is operating properly .
Upon arrival I was told that 2nd classroom on left side of building first floor was blowing cold air and doesnâ€™t have heat. Also, 2nd floor classroom on the left would intermittently blow cold air but system is satisfying. Found first floor classroom RTU wasnâ€™t getting gas. Found maxitrol pressure regulator stuck or frozen. Tapped it a few times and gas released. Had manometer on system and checked pressure. Operating normal now but quoting to replace Maxitrol regulator. Then inspected 2nd floor system. Found unit operating normal but thermostat settings making unit blow cold air. Disabled fan with heat option, unit does this already and fan is being cycled too quickly during call for heat, blowing cold air at first. Then I found unit was programmed for adaptive recovery, causing unit to cycle on before schedule asks it to. Removed adaptation recovery. Tested unit and found it is operating normal.
I ran hot water with a prop shut off valve to the new humidifier. Replaced drain line with pvc. Tested unit for operation and for any water leaks. Humidifier is operating normal. Disregard remaining balance. Customer is paid in full.
