This Kirkwood property scheduled a return service call for boiler inspection and heating unit repair. Riley Plumbing Heating And Air had previously serviced the system. The technician evaluated the three-zone hydronic manifold and verified zone controller operation. Each zone's electronic actuator responded correctly to thermostat signals. The boiler fired properly and maintained temperature setpoints. The Axiom glycol feeder showed adequate fluid levels and proper concentration. System pressure remained stable across all distribution loops. No circulation issues were detected during the diagnostic inspection. The previous toilet replacement had addressed plumbing concerns separately. Multi-system service calls allow technicians to address heating and plumbing needs in a single visit. Properties at elevation require annual heating system verification before heavy snow restricts access. Scheduling inspections early in heating season identifies potential problems before temperatures drop. Book your annual heating inspection now to ensure reliable operation through winter months.
