It is the coldest night of January in Livingston County and the forecast was right. Furnaces are quitting and pipes are splitting, and the people calling you are standing in cold kitchens with a flashlight, deciding who to call next if nobody picks up.
With emergency dispatch on your line, a calm person answers, confirms it is a true emergency by your rules, collects the address and access details and pages your on-call tech. If the tech does not respond, the next name on your list gets the call.
Your on-call tech sleeps through the calls that can wait and gets clear, complete details for the ones that cannot. The customers who called in a panic get a person, a plan and a truck, and they remember who showed up.
