Service Call Day

A 90-minute, 4-round basic Express simulation on running a residential HVAC service day from a first-year technician's seat: triage of service calls by safety and customer risk before route and revenue, honest arrival windows, a measured diagnosis instead of parts-swapping or topping off refrigerant, refrigerant recovery and the venting prohibition under Clean Air Act section 608 (40 CFR 82.154), repair versus replace presented honestly in a written quote, a heat-vulnerable customer, closing jobs so they stay fixed, and overtime against the on-call handoff, for high-school Career and Technical Education in HVAC/R and the building trades, pre-apprenticeship programs and courses preparing EPA Section 608 Technician Certification and NCCER HVAC Level 1.

Tavion Greer, 19, a fictional first-year service technician with Cimarron Breeze Heating & Air, a family-owned company in Tulsa, Oklahoma, runs the board on a heat-wave Tuesday in July 2027 with sixteen no-cool calls for four trucks.

Round by round you decide the order of the board and what customers are told, how to diagnose a unit blowing warm air and what to do with the refrigerant in a leaking system, how to quote a nine-year-old system with a failed capacitor and what to do for an 81-year-old customer with no cooling, and how every job is closed and who takes the last two calls; at each decision point the day is projected again with the decisions taken so far.

Each round is scored on jobs fixed right, heat-risk hours, the callback rate, the day's margin and customer trust, with open violations shown alongside; venting refrigerant or selling a replacement the diagnosis does not support caps the score. English with Spanish.
