Frequently. Zoning and control faults can present as whole-system failures, and a second technician sometimes finds a much smaller cause before the larger work is approved.
Around 5 nights a year, inside a season of roughly 142 freezing nights, close to what Sandown records. Those handful of nights are when a marginal zone stops being an annoyance and starts being a problem.
