Focus on Energy Rebates for Eau Claire Homeowners: Insulation, HVAC, Windows and Audits

Focus on Energy Rebates in Eau Claire: The Short Answer

Focus on Energy rebates are Wisconsin’s statewide utility efficiency offers, and Eau Claire homeowners on a participating utility can stack several of them in one heating season. Focus pays 2026 attic insulation rebates of $650, $750, or $850 by income tier, ENERGY STAR air sealing rebates of $850 to $1,475 when paired with Trade Ally attic or wall insulation, HVAC instant discounts off the invoice, and limited-time window rebates up to $600 per window. Start with the insulation contractors in Eau Claire when the envelope is the weak spot, then branch to HVAC or windows once an assessment shows what pays back.

Xcel Energy (Northern States Power) is on Focus’s participating utility list. Confirm both the electric and gas names on your bill before you assume a measure qualifies, because many heating and cooling rebates need participating service for both fuels.

Focus on Energy Rebates: Who Qualifies in Eau Claire

Does my utility participate?

Focus on Energy is funded by Wisconsin’s investor-owned utilities and participating municipal utilities and cooperatives. The participating utilities page lists Xcel Energy (Northern States Power) by name. Some offers require a participating electric utility and a participating natural gas utility at the time of purchase and installation. Check your bill against Focus’s current list before you buy equipment.

What are the 2026 income tiers for Focus on Energy rebates?

Focus groups households by area median income (AMI) for your county and household size: above 150% AMI (higher-income / standard), between 80% and 150% AMI (moderate), and below 80% AMI (low-income). Those tiers change the dollar amount on insulation, air sealing, many HVAC discounts, and windows. Apply for income eligibility before the work starts. An Income Specialist responds within three business days, and you hand the confirmation number to your Trade Ally. Focus states that retroactive income-qualified rebates are not available. Call 800.762.7077 if you need help with documents such as the first two pages of Form 1040 (Social Security numbers blacked out) or streamlined proof through programs like WHEAP, Medicaid, or SNAP/FoodShare.

Do I need a home energy assessment first?

For ENERGY STAR air sealing rebates, yes: Focus requires an energy assessment along with Trade Ally attic or wall insulation. Trade Ally assessments typically cost about $500 to $700 and show draft paths, comfort problems, and which rebates apply. Focus also offers a free online home assessment tool for a quick overview. Separately, Xcel markets no-cost in-home assessments when Xcel is your heat provider and you received energy assistance or are a tribal member; that page says a typical assessment otherwise costs up to $500.

How much are 2026 attic and air sealing rebates?

For single-family homes with 1 to 3 units, Focus lists these amounts for improvements on or after January 1, 2026:

Measure	Above 150% AMI	80% to 150% AMI	Below 80% AMI
ENERGY STAR air sealing (with attic or wall insulation)	$850	$1,160	$1,475
Attic insulation	$650	$750	$850
Wall insulation	$575	$575	$575
Foundation insulation	$90	$120	$150
Sill insulation	$90	$120	$150
Ducts in unconditioned space	$1,000	$1,000	$1,000
DIY attic insulation and air sealing	$200	$200	$200

Contractor-installed work has to use a Focus Home Performance with ENERGY STAR or Air Sealing & Insulation Trade Ally. Applications are due within 60 days of completion and no later than January 31, 2027 on the insulation program page. Always re-check that page before you schedule, because Focus also notes offers are first-come, first-served and can change.

What attic R-value does Focus require?

Program rules used on the 2026 insulation offer require at least 600 square feet of attic. Attics at R-19 or less must be brought to R-38 or greater, and attics already between R-20 and R-38 must reach at least R-49, with air sealing done with the insulation. DIY attic work must include both insulation and air sealing, cover at least 600 square feet, and reach R-42 or greater. Carbon monoxide alarms must be present on all conditioned floors. The same insulation category generally cannot be rebated again within 1,095 days, with a limited air-sealing exception. For why attic sealing stops ice dams, see our ice dam prevention guide.

What HVAC instant discounts does Focus list for 2026?

Focus’s heating and cooling page advertises up to $1,000 off efficient equipment and notes that heating and cooling are nearly half of average home energy use. Instant discounts (paid to a participating distributor and passed through the contractor) include:

• Natural gas furnace under 300 MBh at 95% AFUE or higher: $100 standard, $400 income-qualified
• Natural gas boilers under 300 MBh: $300 to $450 standard and $500 to $650 income-qualified by efficiency tier
• Air-source heat pumps: $400 to $700 standard and $600 to $900 income-qualified by SEER2/HSPF2 tier (lower amounts when replacing propane)
• ENERGY STAR smart thermostat: $50

Equipment must be purchased and installed between January 1 and December 31, 2026, must replace existing equipment that does the same job, and cannot go into new construction. For furnace sizing, permits, and the furnace discount in context of replacement cost, use our furnace replacement cost guide. For local installers, see HVAC contractors in Eau Claire.

What about water heaters and smart thermostats?

Focus lists instant discounts of at least $300 for a heat pump water heater under 120 gallons at 3.3 UEF or higher, at least $200 for an indirect water heater paired with a 90% or better boiler, and at least $100 for a tankless unit under 200,000 BTUh at 0.87 UEF or higher. Focus says water heating is almost 20% of average home energy use. A $50 smart thermostat rebate also appears for qualifying retail purchases on or after January 1, 2026, with separate rules limiting how many thermostats a household can claim.

How do 2026 Focus on Energy window rebates work?

They are a limited-time material rebate, not a labor rebate. Eligible customers replace single-pane or clear double-pane windows (no Low-E) with ENERGY STAR Version 7 Northern Climate certified units installed by a participating Trade Ally between June 1 and December 15, 2026, while funding lasts. Per-window amounts are $200 (above 150% AMI, home max $3,000), $400 (80% to 150% AMI, home max $5,000), and $600 (below 80% AMI, up to total material cost). A reservation form must be approved before purchase, and at least 51% of the home’s heat must come from a participating utility. Browse window and door companies in Eau Claire when you are ready for quotes, and confirm the contractor is on Focus’s current Trade Ally list.

Focus on Energy Rebates Plus IRA HOMES and Xcel Offers

Can Focus on Energy rebates stack with IRA Home Energy Rebates?

Focus says Wisconsin received $149 million for IRA Home Energy Rebates and that both HOMES and HEAR are available now. You may only participate in one of those IRA programs at a time. HOMES needs a whole-home assessment with modeling, requires at least 20% modeled energy savings, and pays single-family rebates from $1,500 up to $10,000 depending on income and savings tier (for example, 35% or greater savings can reach $10,000 at below 80% AMI, covering 100% of project cost up to that cap). Low-income households can get up to $500 toward the assessment. Focus also notes that qualifying at 80% AMI for IRA already qualifies you for income-based Focus programs. Federal section 25C credits are a separate question: the IRS says that credit is not allowed for property placed in service after December 31, 2025, which is why state and utility rebates matter more for 2026 installs.

What should Xcel customers check beyond Focus?

Start with Focus, because that is the statewide rebate layer Xcel participates in. Then open Xcel’s Wisconsin Home Rebates page, which lists Home Performance, free energy-saving products, AC Rewards, and income-qualified savings among current offers. Dollar amounts on utility-branded add-ons change, so verify them on Xcel’s site the week you sign a contract rather than from an old PDF. If you qualify for Xcel’s no-cost assessment offer, use that visit to build the same improvement list your Focus Trade Ally will need.

Focus on Energy Rebates: When to Call a Pro

Call a Trade Ally when you want attic air sealing and insulation before winter, when you are replacing a furnace, boiler, heat pump, or water heater, or when drafty windows are next on the list. Ask every contractor whether they are a Focus Trade Ally for the exact measure, whether they can file or help with the application within 60 days, and whether income-qualified approval is already on file. Start with insulation contractors in Eau Claire for envelope work, then bring in HVAC or window specialists only for the measures the assessment prioritizes.
