Nowadays, you have an HRV because with the setup you have, in the winter you exhaust warm air and bring in cold air when you flick the switch or your furnace is heating. The HRV has a heat exchanger to not waste the warm air and allows you to set the interval to exchange air without having to flip a switch. You probably missed out on an HRV by a year or so. When we built about 8 years ago, HRVs were standard.

That's the annoying bit right now! Would be nice to run it in the summer nights and not have it transfer that heat to the cool air it brings in.
That being said, it's been much nicer this summer with the HRV, probably keeps it a couple degrees cooler because of the scheduling. And no more mould!
