Interest in heat pumps has increased dramatically in recent years
In addition to a heat pump, I wish my HVAC had a filtered vent from the outside and would be intelligent enough to sometimes just pump in cooler or warmer air from the outside when viable.<p>I don’t like having to shut off my furnace and manually manage windows. But I also don’t want automatic windows.  I just want it to be like, “you’re asking for 21C and we can get there by pumping in outside air rather than using an AC to transfer heat from the inside air to the outside air.”
