The checklist walks the furnace from the heat exchanger out — cracks, gas pressure, the carbon monoxide test, hot surface igniter ohms, inducer and blower amps — and asks your tech to mark every one green, yellow or red.
Then it asks them to present those findings to the customer. On paper that comes down to what the tech can remember, standing in a basement.
So we built the tool. Same points, same three colours, and at the end it writes the summary for you. The carbon monoxide line is the one homeowners actually want to hear about — this is how you show it to them instead of describing it.
