HVAC is trending in #Ontario.
Let's clear the air, #onted.
It should be immediate #VENTILATION, with filtration improvements, for a #SaferSeptember to buy us time, and Indoor Environmental Quality improvements (#IEQ), for the long term. Not generic 'HVAC'. Not "AC".

We say we urgently need quality HVAC in schools (we do!) but HVAC is:
(H)eating the building,
(V)entilating using outdoor air, and
(A)ir (C)onditioning,
where AC = removing heat and moisture.
ALL classrooms have H and V, though often no AC.

In old schools Ventilation was provided naturally, using a chimney effect to cause negative pressure in the school, drawing outdoor air inside. It's unreliable, so these schools were later retrofitted with exhaust fans to force the air out. (if you find unrenovated, send pics!)
