Observed bill reduction after attic insulation retrofit
I’m going to have my attic insulated up to r-60. I was wondering what kinds of reductions project have seen in their heating/cooling bills after performing a similar retrofit.
Let me add some more details. I understand that air sealing is more important than insulation.
My question was more for people that have done a retrofit, have air sealed and also added insulation. I have looked around, and the best I can do is find sites that claim up to “40% odd amount off your bills!” but no actual numbers.
I do understand that everyone’s experience is different, but still, what was your experience? Did you bills go down by a small amount? Or a large amount?
And, while I’m at it, did you add anything else? Heat pump water heater? Mini-split?
While everyone’s experience is different, I would think that being able to share your experience retrofitting and seeing the difference in this particular way could help myself and others when figuring out if they should go whole hog, or something more modest.
Thanks in advance!
