Hey Rob, I see what you're saying with the TED, and I've contemplated looking into that farther. I can see beauty of that being that regardless of whether or not the "perpetrating load" is something that would normally come up on a standard energy audit, it would be able to pinpoint it as a problem. You've been able to make some (what I would characterize as) terrific gains with your unit. If I could reduce my bill that much, I would be pickled tink! Will have to investigate that one some more! Hey Willman! Yeah, the guy with the IR camera is going to do a blower door test too, I just wanted to the IR for curiosity's sake (okay, I'll admit to a gadget factor in there), AND to see if the contractor actually burned me on the insulation (demo and redo are BOTH definitely 4-letter words!). It's supposed to be in the mid 50s tomorrow, so that'd be a good day to start flipping through my breaker box and hanging out at the meter! Heaterman, I've thought about that, but those bills are long gone I reckon. I DO know that prior to the heatpump being replaced, I was sorely hoping that once the new one came my bill would go down. So I know they were high then, but I just can't recall exactly how high. They have, I believe, gradually increased over the years. I think the unit is a Lennox, and I'm not sure about the type compressor but tomorrow is going to be a good day for checking out those fins in the bottom of the air handler too! Thanks guys!!
