While on-site for the hvac preventative maintenance two belts were identified as needing replaced. The Lennox unit closest to the mini-split had the indoor blower motor belt replaced. There were also not an emergency belt. An extra belt was left inside of the blower compartment for use in the future. The exhaust fan for the men’s restroom was also in need of a new belt and it was replaced with a belt that was on-site. There is an extra belt inside of the woman’s bathroom exhaust fan on the roof for an emergency repair if needed. Both the exhaust fan and the Lennox rooftop unit were checked again after the belts were replaced. Both repairs were successful. Thank you, Jon Tech notes: -misc is the price for belts
During this visit the rooftop units were checked and the filters were replaced. The units were cycled to confirm that they are operating normally. The east carrier unit had a condensate drain line that had been knocked apart and was reattached today. A Lennox unit (rtu #2) had the blower motor belt replaced as well as the men’s bathroom exhaust fan belt was replaced. The mini-split that serves the conference room had dripped condensation from the suction line insulation. The insulation to this unit was secured today. The mini-split, exhaust fans and all roof top units are functioning at this time. Thank you, Jon
The Carrier equipment was found in excellent condition at this time. All functions were within range. The Lennox equipment was found in solid condition with the exception of the unit that has lost 2nd stage heat due to a blown fuse. A service call is in fair order for both the fuse and the contactor. In addition to this the ax44 belt should be replaced. For the record there were no emergency belts on site. It is possible that they have been consumed. We should have at least two hidden away inside of the equipment. I will backchannel further notes via email on this visit. As it stands we can bill this out. There will be a service visit in the future with parts on hand and further attention to the wants/needs that were brought to my attention by Janet. For ref. Women’s bathroom, milk house heaters, etc. These will be channeled via email.

10-16-23 AC is not working in the great room Found the north carrier RTU not working. Unit did not have power to it. When I tested the incoming voltage it was all over the place acting like a partially tripped breaker. The circuit breaker is located in the kitchen storage room breaker #2 It was not tripped. I left the breaker off, remove the electrical panel for the disconnects switch on the unit. Found the incoming connections loose. Re-landed all incoming power connections.i Turn the power back on system is working at this time While on site, I checked the south great room RTU unit and also the kitchen RTU. They were also loose on incoming power, but they were working all three units. Income connections are tight.
