Your peak is not spread evenly across the year. Heat pump calls come from September to November, air conditioning from May to July, pools in spring and at the end of the season.
Those are exactly the weeks your engineers spend all day on site.
A caller who gets no answer calls the next company on the list; one who leaves a voicemail has no idea whether anyone heard it.
Kinetara takes that part over: which appliance has failed, where the property is and whether the case is urgent - then sends the record by the route you defined, straight to the on-call engineer or into the morning review.
