The temperature drops below freezing on a Sunday night. By seven on Monday morning an engineer has thirty one voicemails.
They are all urgent. Some are elderly people with no heating, some are frozen condensate pipes that could be resolved in ten minutes over the telephone, and some are systems working slightly less well than usual.
He listens to all thirty one, telephones back in the order he received them, and reaches the most vulnerable caller at half past four in the afternoon.
The first failure: the demand is weather driven and clustered
A cold snap produces a week of breakdowns in two days. This is entirely predictable, it happens every winter, and almost nobody plans capacity around a forecast.
The second failure: everything arrives as urgent
Every caller with no heating in freezing weather describes an emergency, and they are not wrong from where they are standing, which makes self reported urgency useless as a sort order.
The third failure: the vulnerable callers are not prioritised
Elderly people, young children and anyone with a health condition. Nothing in a voicemail queue distinguishes them and they are frequently the most patient callers.
The fourth failure: the frozen condensate pipes are not resolved remotely
A significant share of cold snap failures are a frozen condensate pipe, which many customers can resolve themselves in minutes with clear instructions.
The fifth failure: the simple checks are not walked through
Pressure, a tripped switch, a thermostat setting, a timer changed by somebody. Several calls a day are resolved by asking three questions.
The sixth failure: the safety cases are not separated
A gas smell or a carbon monoxide alarm is not a heating enquiry and must be routed immediately with the correct advice, rather than queuing behind a cold radiator.
The seventh failure: nothing is captured properly
Make, model, age, what is showing on the display and what the customer has already tried. An engineer arriving without this arrives less prepared than he could have.
The eighth failure: the photographs are not requested
Of the appliance, the display and the pressure gauge, which frequently identify the fault before a visit, which is the approach in heating engineers and the photos that speed up quotes.
The ninth failure: the interim advice is not given
Temporary heating, protecting pipes, keeping one room warm and what to do about hot water. Useful, immediate and rarely offered.
The tenth failure: the honest timescale is not stated
A customer told they will be seen tomorrow afternoon plans around it. One told nothing telephones four more engineers and takes whoever answers.
The eleventh failure: the existing customers are not prioritised visibly
Service plan customers expect priority and frequently do not receive it, which undermines the entire proposition of the plan.
The twelfth failure: the same fortnight recurs every year
Forecast in advance, identical in shape, and handled reactively every time, which is the pattern in heating breakdowns that arrive on the coldest nights.
The fix: triage at the hour the call arrives
An assistant that identifies vulnerability and safety cases immediately, walks somebody through a frozen condensate pipe or a pressure top up, captures the appliance details and photographs, states an honest timescale and orders the queue by genuine urgency means the most vulnerable caller is reached at eight rather than at half past four. That capture is what how hvac companies capture emergency calls with a chatbot describes, and the same overnight surge in emergency and broken bracket enquiries.
