I spent about $8,500 on a whole-house heat pump system last fall, convinced it was a waste. Our old gas furnace was fine. But after one winter in Seattle, our heating bill dropped by almost 40 percent. The installer showed me the energy use numbers and I couldn't argue. Has anyone else seen savings that big in the first year?
Had the same doubt" is a pretty mild reaction for something like a utility bill. I mean, unless the amount was off by hundreds, it's probably just a minor adjustment they'll fix next cycle. Are people really out here stressing over estimated readings that much?
