You have probably seen that number thrown around. 70% savings. Real or just marketing?
The honest answer: yes, but it depends on your fuel type. Homes on oil or propane heat typically see 60 to 70% savings. Natural gas homes see closer to 40 to 50%. A typical NY home spending $4,500/year on oil heat and AC could realistically drop to around $1,500/year after switching to geothermal.
Why does NY make such a strong case? The ground stays 50 to 60 F year-round, so geothermal efficiency holds steady even during the coldest Hudson Valley winters, unlike air source heat pumps that lose performance below 30 F.
The best part? NY incentives are still active in 2026. NYS Clean Heat rebates go up to $25,000 for full fossil fuel replacement, and the NY State Tax Credit covers 25% of your installation cost capped at $10,000. Most homeowners replacing oil or propane see a payback period of just 6 to 10 years.
If you own an older home in New York, New Jersey, or Connecticut, you are likely losing money every day through air leaks and poor insulation.
80% of homes built before 1980 have insufficient insulation. Spray foam is the only solution that seals and insulates in one step, cuts energy bills by 30 to 50%, and lasts 80+ years without losing performance.
The best part? Rebates of up to $10,000 are still available in NY, NJ, and CT in 2026 through NYSERDA, NJ Clean Energy, and Energize CT.
We put together a complete homeowner's guide covering open cell vs closed cell foam, where to apply it, and how to claim your rebates.
