What insulation rebates pay in Aurora
Amounts come from Xcel Energy's 2026 rebate summary, last read on September 29, 2026. Xcel's own page would not load for our reader on October 5, so check it for the current caps. The Colorado Energy Office page was read on October 5, 2026.
Xcel attic insulation
Gas-heated homes get 1.5 times the standard amounts, which works out to $750 by our math. Applies to homes heated by Xcel gas or electricity.
Xcel wall insulation
Same 30% rule. Gas-heated homes get 1.5 times, or $525 by our math.
Xcel air sealing
Gas-heated homes get 1.5 times, or $600 by our math.
State income-based rebates (HEAR)
Up to $1,600 for insulation, air sealing and ventilation while it was open. The single-family program is now closed.
Federal tax credit (25C)
The credit for insulation and air sealing ended for spending after December 31, 2025.
Working it out
An air sealing job that costs $900 earns 30%, or $270, under the $400 cap. An attic top-up that costs $1,200 earns $360. Do both in one visit for $2,100 and you would collect $630 from Xcel, because each measure is capped on its own. In a gas-heated home the caps are 1.5 times higher, but at these prices you would not reach them, so you would still collect 30%. Caps only bite on larger jobs.
What Aurora homes look like
The American Community Survey (2020 to 2024) counts 152,377 homes in Aurora. About 62% of households own and 38% rent. About 53% of homes are detached houses. Only 37% were built before 1980 and just 1% before 1940, while 29% were built in 2000 or later.
That is the opposite of Denver's mix. Most Aurora houses are newer, so the first question is what you already have. Ask a contractor to measure the depth of insulation in your attic and to run a blower door test, which shows how leaky the house is. Do not buy a measure you do not need.
Attic top-up and air sealing first
For a newer house, the usual targets are the attic floor and the air leaks around it. Xcel's 30% covers both, with a $500 attic cap and a $400 air sealing cap. Wall insulation, which has a $350 cap, is a harder job in a finished house and is less often the right place to start. Your contractor should explain why each measure is on the quote.
What Aurora heats with
About 62% of Aurora households heat with utility gas, 34% with electricity and almost none with oil. Xcel's rebate sheet gives gas-heated homes 1.5 times the standard caps, and says so for Xcel gas customers. If you are in the 34% on electric heat, insulation saves you the most per dollar, because electric heat is the costliest to run.
Renters in Aurora
About 38% of Aurora households rent. A tenant usually cannot insulate an attic, so the useful move is to ask a landlord to look at the rebate. Xcel pays the customer who pays for the work.
What changed in 2026
The federal credit for insulation ended after 2025, and the Colorado Energy Office closed its single-family income-based rebate program in August 2026. That program could pay up to $1,600 for insulation, air sealing and ventilation. Aurora's counties, Adams and Arapahoe, were in its Front Range region.

Common questions
How much does Xcel pay for insulation in Aurora?
30% of cost, up to $500 for an attic, $350 for walls and $400 for air sealing, with 1.5 times for gas-heated homes, per Xcel's 2026 rebate summary.
Does Aurora have its own insulation rebate?
We could not confirm one from a city page, so we list none.
Is the income-based state rebate still open?
No. The Colorado Energy Office says the single-family program is closed.
Is a newer house worth insulating?
Sometimes. A blower door test and an attic depth check show whether you have leaks or thin insulation. Skip measures you do not need.
Is there a federal tax credit?
Not for 2026. It ended for spending after December 31, 2025.
