  • An HRV tempers the incoming air with the air going out no matter the season. So, in winter, it recovers some heat from the exhaust air and exchanges it with the cold intake air, keeping heat inside.

    In the summer, it’s the opposite. The exhaust air cools the hot intake air, keeping the heat outside.

    It’s essentially always working for your benefit (except for one edge case that I can expand on if you’d like), always providing fresh air and exhausting stale air while helping to keep the interior temperature where desired.

    I’d recommend keeping it on all the time, no matter if you open windows or not.








  • I would also argue the bridge is ever changing as well. It has different vehicles crossing it, every tire wears the surface, the materials expand and contract with temperature, the structure weathers continuously.

    Just because one doesn’t notice, doesn’t mean something doesn’t change.

    Philosophically, it really all boils down to the only thing that exists is the present. The past doesn’t exist, the future doesn’t exist. The only thing that is real is what is happening in this very moment.

    The river is not the same as when you crossed it this morning, neither is the bridge. It is only as it exists now, and it will never exist in this same way at any other time.
