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.
