customer this morning wants me to settle 68 vs 72 on his thermostat 'like a coach's challenge,' so i pull out the little flag i keep in the truck for exactly this, throw it on his floor, and rule 70 with replay confirmation, no arguments in my house. took less time than dallas needs to blow a two-score lead. he's happy, furnace is happy, and somewhere in texas a coordinator is currently losing a challenge he shouldn't have thrown in the first place. filed under 'tuesday, hvac, still delicious.'
