Do New Windows Actually Save You Money? The Truth About Energy Efficiency and Tax Credits
June 23, 2026
Article Summary
New windows do save money — through lower energy bills, year-round comfort, and a federal tax credit worth up to $600 in 2026. Here's the honest breakdown for Indianapolis homeowners.
Do new windows really pay for themselves in energy savings?
I want to address something I hear from Indianapolis homeowners pretty regularly:
"I've heard new windows will pay for themselves in energy savings — is that actually true?"
The honest answer is yes, but with context. The size of the win depends on what you have now, how big your home is, and how leaky those existing windows really are.
How old windows quietly drain your energy bill
Raylen Dorrell: Here's what's real. If your windows are 20 or more years old — single-pane, or older double-pane that has failed — you are losing heat in the winter and cool air in the summer.
Indiana has serious temperature swings. That's not an opinion, that's physics.
Modern ENERGY STAR certified windows significantly reduce that transfer, and most of our customers notice lower utility bills — especially through the first full winter after installation.
What's a realistic payback timeline for replacement windows?
The payback timeline depends on two main factors:
Your current windows — single-pane and failed double-pane lose far more energy than newer units
Your home's size — more windows multiply both the savings and the upfront cost
For a home with 10 to 15 windows that's been drafty for years, energy savings can be meaningful. For a home that's already reasonably tight, the comfort improvement matters more than the math — fewer drafts, more consistent room temperatures, and less work for your HVAC system.
What does the 2026 federal energy efficiency tax credit cover?
Now — the part that surprises a lot of homeowners.
As of 2026, the federal energy efficiency tax credit allows homeowners to claim:
Up to 30% of the cost of qualifying ENERGY STAR windows and doors
Up to $600 per year for windows
That's real money that comes back to you at tax time. We can walk you through which of our products qualify before you ever sign a contract — so the credit is locked in from day one.
What's the bottom line on energy-efficient windows in Indianapolis?
The bottom line is simple:
New windows save you money on energy.
They also save you money on comfort — harder to put a number on, but just as real.
The 2026 tax credit puts up to $600 back in your pocket.
If you want to understand what the actual numbers look like for your home specifically, we're happy to walk through it with you.

Frequently Asked Questions
Do new windows really lower utility bills in Indianapolis?
Yes. If you're replacing single-pane or failed double-pane windows, ENERGY STAR certified replacements significantly reduce heat transfer — and most Indianapolis homeowners see lower bills starting in the first full winter after installation.
How much can I claim with the 2026 federal energy efficiency tax credit?
In 2026, homeowners can claim up to 30% of the cost of qualifying ENERGY STAR windows and doors, capped at $600 per year for windows.
How old do my windows need to be before replacement makes financial sense?
A common threshold is 20+ years. Single-pane windows or older double-pane units with failed seals are the strongest candidates for energy-driven replacement.
Which windows qualify for the federal tax credit?
Only ENERGY STAR certified windows that meet the IRS requirements qualify. Modern Day Window will walk you through which of our products meet the standard before you buy.
Is the comfort improvement worth it if I won't break even on energy alone?
For many homeowners, yes. Fewer drafts, steadier room temperatures, and less HVAC strain often matter more day to day than the exact payback math.
Can I claim the window tax credit every year?
The $600 annual cap on windows resets each year, so homeowners replacing windows in phases may be able to claim qualifying costs in multiple tax years. Confirm specifics with your tax preparer.
