Which utility actually pays for insulation in Greeley?
The gas utility — but not the same gas utility in every town this site covers, and that is the part to settle before anything else. Atmos Energy serves natural gas in Greeley, Evans and Eaton and runs the residential rebates that cover insulation and air sealing work there. In Johnstown, for most of Milliken, and for most locations in Severance, natural gas comes from Xcel Energy instead, and Xcel sets out its own insulation and air sealing rebate terms — including who qualifies — on its rebate page. The Atmos program described below is Atmos's, and it describes what Atmos offers its own customers; check which company bills you for gas before you plan around it.
Why the confusion exists: the large metro immediately south of here has one utility supplying both electricity and gas, and that utility's insulation rebate is well publicized. Greeley's fuels come from different companies. A rebate program built around customers whose heating fuel it supplies behaves very differently when it does not supply your heat.
One thing this site will not tell you is who your electricity comes from. State utility-territory data returns overlapping boundaries for more than one provider across this area on records several years old, and no primary source settles it cleanly. Your own bill is the authority, and the Xcel section below sets out where that answer changes what is on offer and where it does not.
What does Atmos actually pay, and what does it require?
This is the published residential structure — which measures are covered, how each one is calculated, and what each one requires. The amounts themselves live on the Atmos page, for the reason given under the table.
| Measure | How Atmos calculates the rebate | Qualifying condition |
|---|---|---|
| Attic insulation | 75% of project cost, capped | Starting R-value below R-20 |
| Air sealing | Flat amount, not a percentage | Blower door showing 20% CFM(50) reduction |
| Crawlspace / basement insulation | 75% of project cost, capped | No pre-existing insulation required |
| Floor insulation | 75% of project cost, capped | Starting R-19 or less |
| Wall insulation | 75% of project cost, capped | Starting R-5 or less |
| Duct sealing | Flat amount, not a percentage | Blower door showing 20% CFM(25) reduction |
| Rim joist insulation | 50% of project cost, capped | Starting R-15 or less |
The caps and the flat amounts are the part Atmos revises, so they are not printed here. Atmos publishes the current figure for every measure in this table on its own Colorado residential rebate page — read them there, and read them again before you scope, because Atmos states its amounts are subject to change.
The conditions matter as much as the money. The premise has to be served by Atmos. The application is due within 60 days of the installation or service — the most common way people lose this money is simply missing that window. Residential new construction is excluded. Insulation receipts have to state the R-value and the amount installed, so the paperwork has to be right at the time of the job, not reconstructed later.
One requirement that is notably absent: there is no registered-contractor list to navigate. Atmos asks that the installing contractor hold an applicable license. That is a meaningfully lower bar than programs that restrict you to a utility's own approved roster, and it means you can choose on merit rather than on membership.
Atmos states that its rebate amounts are subject to change and that rebates are available only until program funding is fully allocated. This site does not publish those amounts. Read the current ones on Atmos Energy's Colorado residential rebate page before scoping work.
What if the work is out of reach financially?
Then the program to look at is not a rebate at all. The Colorado Weatherization Assistance Program does insulation work — attic, floors, and walls — at no cost for income-qualified households. In Weld County it is delivered by the Energy Resource Center's Northern Regional Office in Berthoud, reachable at (970) 617-2801.
The income limits are higher than most people assume, which is why this gets skipped by households that would qualify. Eligibility runs to the highest of 60% of state median income, 80% of area median income, or 200% of the federal poverty level. On the Colorado Energy Office's own WAP income eligibility chart that currently works out to $70,000 for a single-person Weld County household and $99,920 for a household of four (checked September 10, 2026). Those limits are set for each federal fiscal year and the state re-publishes them annually, so the Colorado Energy Office's Weatherization Assistance Program page carries the current Weld County figures, and it is worth checking rather than assuming you earn too much. If you are already enrolled in LEAP, SNAP, SSI, TANF, or AND, you qualify automatically without a separate income determination.
The honest caveats: homes weatherized in the previous 15 years are not eligible, meeting the income test does not by itself guarantee service, and there can be a waiting list. Energy Outreach Colorado's CARE program is a second no-cost path using the same income thresholds, and Weld County participates in it.
Does the Xcel insulation rebate apply to my Greeley home?
Probably not in any amount worth planning around, and this is the section most likely to contradict something you have read elsewhere.
Xcel's own regulatory filing for the program states that eligible customers are those with a combination of residential electric and natural gas service, gas-only service, or "electric-only service who are electrically-heating their residences." Its published rebate summary scopes the air sealing and insulation table with two headings rather than one. The first heading covers you if your home is heated by natural gas or electricity provided by Xcel. The second — the reduced one — is narrower than it first looks: it reaches you only if your home is heated by a fuel Xcel does not supply, and your electric service is Xcel's rather than another company's, and the house has central air conditioning. Central air conditioning is a cooling fact rather than a heating one, and on that tier it is a requirement rather than a description: Xcel's fulfillment administrator lists it under "Rebate Eligibility Requirements" and titles that tier "Cooling Customers Only."
A Greeley home heated by an Atmos gas furnace does not sit in the tier the headline amounts belong to. Whether the reduced tier reaches that home instead turns on two further facts about the house itself — whether its electric service is Xcel's rather than another company's, and whether it has central air conditioning — and, as above, this site does not tell you who supplies your electricity. This site does not publish those numbers as Greeley promises in either direction, because Xcel revises them on its own schedule and any amount printed here would be a promise with an expiry date on it. Xcel publishes the current amounts itself, and that is where they should be read.
Where Xcel genuinely may apply: if your home is heated electrically — a heat pump or electric resistance heat — then the electric-heating branch of that eligibility rule is the one that fits you, and the program is worth investigating directly.
An honest disclosure about the above. The eligibility language quoted here comes from Xcel's own regulatory product filings, which are several years old. The two headings above are read from Xcel Energy's 2024 Rebate Summary Information Sheet for Colorado residential energy efficiency programs, effective January 1, 2024 — the most recent edition Xcel serves from its own site, checked again on September 21, 2026 — and the same conditions appear today on the insulation and air sealing rebate page that EFI, Xcel's fulfillment administrator, operates for Xcel. A newer 2025–2026 summary exists, but nothing in this site's records shows it being retrieved from Xcel rather than from a third-party copy, so it is not what the wording above rests on. Xcel's live rebate page is a JavaScript application that returns no readable content to automated retrieval. Treat the eligibility rule above as the documented structure, not as today's guaranteed terms, and confirm current eligibility directly with Xcel before making any decision that depends on it.
Which programs are dead or do not reach Greeley?
Three that come up constantly and pay nothing here.
- The federal tax credit. The Section 25C energy efficient home improvement credit was terminated early and expired December 31, 2025. It is not available for 2026 work. Any page still offering it as a reason to act is out of date.
- Colorado's HEAR program. Closed. The state energy office's own dashboard shows zero funding remaining and the program closed for both regions, and Weld County sits in the region that closed first. Note that the state's program page and FAQ are themselves stale on this point — they still describe a second region as open past a date that has passed. The dashboard is the current record.
- Power Ahead Colorado. Inapplicable twice over. It funds heat pumps rather than insulation, and its eligibility requires being in a municipality or county that participates in the Denver Regional Council of Governments. Greeley is not a member; this area is served by a different regional planning organization. Several towns in the far southwest of the county do participate, which is likely where the confusion starts.
Naming dead programs matters because they are the ones used to manufacture urgency. There is no deadline pressure on any live program here except the Atmos 60-day application window after your work is done, and the fact that Atmos funding lasts only as long as it lasts.

What the data says
According to Atmos Energy, Atmos Energy rebates residential attic insulation at 75% of total cost where the starting R-value is less than R-20, and publishes the amount that rebate currently pays on its own rebate page.
According to the Colorado Energy Office's Weatherization Assistance Program, the Weatherization Assistance Program provides no-cost weatherization services for qualified residents and homes, and lists insulation in attic, floors, and walls among the services a household may receive based on the results of its required free home energy audit.
According to the Colorado Energy Office, “the HEAR single-family program is now closed for both Region 1 (the Front Range) and Region 2 (All Other Counties).”
Take the next step
Want the rebate math done on your actual house?
The free in-home assessment measures what is in your attic now, tells you whether it clears the Atmos qualifying threshold, and prices the work with the rebate already applied. If you look likely to qualify for the no-cost state program instead, you will be told that — it is a better outcome for you than a rebated invoice.

We've Got It. Here's What Happens Next.
We've got your info and are routing it to a local pro. When they call, here's what to look for in the quote you receive: (1) R-value target — Greeley builds to the 2021 IECC, which puts attics at R-60, and accepts R-49 only where the insulation carries its full uncompressed depth over the wall top plate at the eaves; anything less is under-spec. (2) Air sealing scope — insulation alone does nothing if air leaks aren't sealed first, so it belongs on the quote as its own line with its own scope, and a blower door test is what documents the before-and-after. (3) Rebate handling — ask who files the rebate paperwork with your gas utility, and confirm what that utility's filing deadline is and that the application will go in inside it. (The federal IRA Section 25C tax credit ended December 31, 2025, and Colorado's HEAR program is closed. Which utility to ask about an insulation rebate depends on your town: Atmos Energy's residential rebates are the primary insulation rebate programs in Greeley, Evans and Eaton, while the natural gas utility is Xcel Energy in Johnstown, for most of Milliken, and for most locations in Severance — Xcel sets out its own insulation and air sealing rebate terms on its rebate page. Income-qualified households can get insulation work done at no cost through the state Weatherization Assistance Program.) (4) Removal scope — older homes often need old insulation removed before new install. If a quote skips all four, get another quote.
Frequently asked
What do Greeley homeowners ask about insulation rebates?
Why does the gas utility pay for insulation instead of the electric company?
Because insulation mostly saves heating fuel, and in Greeley the heating fuel is gas. Utility efficiency programs are built around the energy the utility actually sells you, which is why a gas utility funds envelope work generously and an electric utility funds it thinly unless your heat is electric. It is not an oddity — it is the logic of the whole system, and it happens to work in Greeley homeowners' favor. The same logic points at a different company in some of the towns on this site: in Johnstown, for most of Milliken and for most locations in Severance the natural gas utility is Xcel Energy rather than Atmos Energy, so it is Xcel's published rebate terms that apply to a home there.
How much can I realistically get back on an attic project?
On the attic insulation itself, 75% of project cost up to a cap, plus a separate air sealing rebate if the work meets the blower door threshold. Whether you reach the cap depends on your project's size and cost. What you can rely on is the structure: attic work is percentage-based rather than a small flat amount, so a modest job still gets most of its cost covered rather than a token contribution. The cap and the air sealing amount are what Atmos revises, so they are not printed here — the Atmos rebate page carries no effective date and states amounts are subject to change and available only until program funding is allocated, so read the current numbers there before you scope.
What is the single easiest way to lose this money?
Missing the 60-day application window after the work is done. It is the most common failure and it is entirely avoidable. Agree in writing, before work starts, who is filing the application and when — and make sure your insulation receipt states the R-value and the amount installed, because the application requires both and reconstructing it afterwards is painful.
Do I have to use a contractor from an approved list?
No, and that is a genuine advantage of this market's program. Atmos asks that the installing contractor hold an applicable license — there is no utility-maintained roster you are restricted to. You can choose on the quality of the scope and the willingness to measure, rather than on who signed up with a utility.
Is the free state program only for very low incomes?
No, and this is the most common reason people who qualify never apply. The Weld County limits are higher than most people guess: on the Colorado Energy Office's WAP income eligibility chart they currently reach $70,000 for one person and $99,920 for a household of four, checked September 10, 2026. They reset every federal fiscal year, so the Colorado Energy Office publishes the current figures on its own Weatherization Assistance Program page. Enrollment in LEAP, SNAP, SSI, TANF, or AND qualifies you automatically regardless. It costs nothing to check with the Energy Resource Center in Berthoud, and the work itself is free if you are eligible.
My home was built after 2010 — is there a rebate worth chasing?
Probably not, and the rebate structure itself tells you so. The full attic rebate is aimed at homes whose existing insulation starts below R-20, and a post-2010 attic is likely above that. That is the program signaling where the savings actually are. If a room is uncomfortable, get the cause diagnosed rather than buying insulation to qualify for a rebate you may not qualify for anyway.
Which program should I look at first?
The free state weatherization program, before you scope anything. It does attic, floor and wall insulation at no cost for income-qualified households, and no-cost work is a better outcome than paid work with a rebate against it — which is why it belongs first even though it is the worse outcome for anyone selling you insulation. The Atmos rebate covers the same measures on its own terms. Each program sets its own rules about what it will fund on a given project, so ask both of them about yours before the scope is fixed.
