I have to do something about my HVAC in my house. Oh, its effective, its just wasteful. Its the one thing neither of us paid much attention to when we were working with the builder to design the house. We just let the HVAC contractor design the three zones and we got what we got. In winter, the upstairs is 1000 degrees and the downstairs is comfortable. In summer, to keep the upstairs liveable you have to keep the downstairs thermostats lower than you normally would. We keep our thermostats set on 74 in summer typically and 71 in winter, so we're not dogging it. The thing I can't figure out is the zoning of the damn thing. It makes no sense to me the way it's zoned.
So how does one go about redesigning the HVAC? And what do you look for in a design that makes sure you care for that stuff? I'd hate to redo the whole damned thing only to have little or no improvement. I've partially fixed the upstairs heat problem by installing a huge ceiling fan in the upstairs 'game room', which is actually a big upstairs open living room. That keeps a lot of that hot air circulating. But its a constant seasonal battle of opening and closing registers and making certain to keep bedroom doors opened or shut and so on. I'm sick of it.
