Estimates only. Based on typical Minnesota heating costs and the EPA ENERGY STAR finding that air sealing plus insulating attics and rim joists saves an average of about 15% on heating and cooling. Every home is different; a free on-site assessment gives you real numbers.
How we calculate it
We start from typical annual heating costs for Minnesota homes by fuel type, adjusted for your home size and how your current insulation is holding up. If you enter your real heating bill, we use that instead.
Savings ranges come from published efficiency research, anchored by the EPA ENERGY STAR finding that air sealing combined with insulating attics and rim joists saves an average of about 15% on heating and cooling costs. We deliberately show conservative ranges. If anything, homes with older insulation tend to land higher.

How accurate is this savings calculator?
It is an honest ballpark, not a quote. The model uses typical Minnesota heating costs by fuel type and published research, including the EPA ENERGY STAR estimate that air sealing plus attic and rim joist insulation saves an average of about 15% on heating and cooling. Entering your real annual heating cost makes it noticeably more accurate. A free on-site assessment is the only way to get real numbers for your home.
Why does spray foam save more than the insulation I have?
Most heat loss in Minnesota homes rides on air leaking through gaps, not just through thin insulation. Spray foam air seals and insulates in the same pass, which is why sealing the attic and rim joist typically outperforms simply adding more of the same material.
What does an insulation upgrade cost?
It depends on the areas treated and the material. Our online cost estimator gives you a transparent price range in about a minute, and an in-person quote is always free.
