In Ontario, an air-conditioning failure is not a show-stopper. However hot it is this week, the weather will turn before next week is out, and even steamy days are tolerable if the temperature drops below 20°C at night.
This furnace crisis was caused by a defective switch that had cut off the electricity to the fan and the condensate pump. That’ll teach me to situate the appreciation — I had myself braced for a fatal diagnosis, and it turned out to be a bad case of “machine not switched on”.
Oh, well. Six months from now, It will be something elde.
