I checked the air filter. Customer needs to order a box of 28*30*2 filters. I checked the electrical wiring and electrical systems, including the auxiliary heat strips and all are within specification. I reset blower speeds to factory settings 2,5,7,10 from 2,7,9,10. This will blow warmer air from the unit. I operated the unit on second stage heating mode and recorded 25-30 degree temperature rise across the air coil. I set the flow rate to 3.5psi pressure drop so I could calculate heat of extraction and compare it to printed data. Heat of extraction is 28,000+ btu/hr which is better than printed data. Unit operating normal. Customer and I talked about a few accessories including a humidifier, surge protector and a WiFi thermostat for the geo unit. I sent estimates for all.

I pressurized the ground loop to 65psi. I vacuumed the EAC pre filters and reset the led panels. I checked the electrical wiring and electrical systems, including auxiliary heat strips, all are within specification except for the voltage absorption system for unit #1, which was replaced. I operated the units on second stage heating mode and recorded 25+ degrees delta temperatures across the air coil and normal heat of extraction. Both units are operating normal.

Found no issues with vent pipe. While there I gave options for a uv light install since there experiencing some impurities in the water still after there filtration system. Also gave a sales lead request form and a membership form. They were thinking of a geothermal unit installation. They also have a gas powered tankless water heater installed which is why I recommended our service agreement.

Upon arrival I was told that multiple classrooms are hearing a very loud humming sound when Unit runs. Went to roof and system was running in ac mode. Could hear humming from inside classroom and right outside of unit. Opened up blower panel and found everything in tact and functioning normally. Belt used was AX48. Cannot use cogged (X) belts on Carrier Equipment. Per Carrier, it makes the belts wear faster and creates noise problems because their pulleys are designed for normal belts. Found spare A48 inside of another blower panel in a different unit. Replaced AX48 with A48 and ran fan only. Blower is quiet and not making any noise. Called for Ac and checked operation. Found no additional problems. Unit operating normally. **Next time we return we need to bring (2) A48 belts for spares. Customer also informed me that roofers have had to come out to patch the roof several times since we got the contract. She asked if we can be extremely careful when up there, not to drop any tools, par

Unit had the red drain light flashing. I cleaned the condensate pan and drain lines and flushed out with hot water. I purged the air from the drain line and it drained properly. I confirmed proper flow rate and heat of rejection. I checked the electrical wiring and electrical systems, all are within specification. I increased low and high blower speeds by one but left the fan speed the same. Loop pressures are above 60 psi, so there was no need to pressurize the ground loop. Unit operating normal. Customer does not want estimates unless something is in need of repair.

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 can’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.

Upon arrival I was told that heat in Cheetah room wasn’t working again and now the heat in Zebra room doesn’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 “heat on” but the gas would turn off to th burners when the thermostat displayed “heat 2.” 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 doesn’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.

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 wasn’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 8” 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 wasn’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.

Upon arrival I was told that 2nd classroom on left side of building first floor was blowing cold air and doesn’t have heat. Also, 2nd floor classroom on the left would intermittently blow cold air but system is satisfying. Found first floor classroom RTU wasn’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.
