His efficiency data is tarnished by the leak. It was doing its best, but it was leaking, so it probably had to work harder to get the proper temperature. Also, he's comparing year over year - years have differences in weather. He's comparing one year's gas furnace use to 9 years of heat pump use - this is not a great comparison. Also, if he'd have had solar, or some other source of electricity, that was cleaner, say nuclear or solar or wind, it would be a lot less. |
