Last week centered on practical field issues and job trends. Remote-friendly HVAC roles kept popping up in the jobs threads, while service techs compared approaches to billing diagnostic time and using Bluetooth probes to set expectations with homeowners. Troubleshooting talk was strong—quick methods to track 24V shorts, trustworthy CO readings on furnaces, and whether particle counters help validate filter performance. Rounding it out, folks swapped notes on heat pump behavior around 40°F, plus a light thread about strip heat and bread that still managed to touch on load and control nuances.
