The Costco Home Improvement Services Guide 2026: Solar, HVAC, Windows and the 10% Shop Card Most Members Miss

Most Costco members have never heard of ReMEMBER.

They know about the rotisserie chicken. They know about the gas savings. They may know about the pharmacy and the hearing center. But the ReMEMBER home services program — Costco's partnership network that delivers major home improvement projects at vetted-contractor quality with a 10 percent Costco Shop Card on the project value — is one of the most financially significant and most consistently underused member benefits available through any Costco membership.

On a $15,000 HVAC installation: $1,500 back as a Costco Shop Card. On a $25,000 solar panel system: $2,500 back. On a $20,000 window replacement project: $2,000 back. On a $10,000 bathroom remodel: $1,000 back.

These are not percentage discounts applied at the point of sale. They are Costco Shop Cards — equivalent to cash at any Costco warehouse or Costco.com — delivered after the project is completed. The Shop Card does not reduce the project price; it returns 10 percent of the project value as a post-completion rebate. Combined with the Executive member's 2 percent annual reward on qualifying Costco services purchases, the combined return on a major home improvement project booked through Costco's home services program can reach 12 percent of the total project value.

For a homeowner planning a significant home improvement project — HVAC replacement, rooftop solar installation, new windows, kitchen cabinet refacing, or any of the 14 services in the Costco home services portfolio — checking whether the project is available through Costco's program before booking a contractor independently is a five-minute search that can deliver thousands of dollars in post-project credit.

How the Costco Home Services Program Works

The Costco home services program operates through a network of vetted, pre-qualified service partners that Costco has established relationships with in specific geographic markets. The program structure is different from buying merchandise at the warehouse — Costco does not directly employ the contractors, store installation inventory, or manage the project. Instead:

Costco partners with established service providers — Lennox for HVAC, Sunrun for solar, Infinity from Marvin for windows, Generac for generators, EcoWater for water treatment, Reborn Cabinets for cabinet refacing, and equivalents across the other service categories.

Members access the program through Costco.com → Services → Home Services, where they can explore available services, check geographic availability, and initiate a free in-home consultation.

The free in-home consultation is the gateway to every project — a Costco-partner specialist visits the home, assesses the scope, and provides a project estimate. There is no obligation to proceed following the consultation.

When a member decides to proceed, they book the project through the Costco partner's system using their Costco membership number. Upon project completion, Costco issues the 10 percent Shop Card based on the pre-tax project total.

The Shop Card timeline: the card arrives after project completion, typically within several weeks of the project being marked complete in Costco's system. It is issued as a digital or physical Costco Shop Card with no expiration date — redeemable at any U.S. Costco warehouse or on Costco.com.

The 10% Shop Card Math: What Members Actually Get Back

The 10 percent Shop Card is the headline benefit — but its financial impact varies dramatically by project size, making it most commercially significant for the largest home improvement categories.

The math across Costco's home service categories:

Project Type	Typical Project Cost	10% Shop Card Value
HVAC installation	$8,000 - $15,000	$800 - $1,500
Rooftop solar system	$15,000 - $35,000	$1,500 - $3,500
Window replacement (whole home)	$10,000 - $25,000	$1,000 - $2,500
Bathroom remodel	$8,000 - $20,000	$800 - $2,000
Flooring (whole home)	$8,000 - $15,000	$800 - $1,500
Cabinet refacing	$5,000 - $12,000	$500 - $1,200
Gutter installation	$2,000 - $5,000	$200 - $500
Generator installation	$5,000 - $12,000	$500 - $1,200
Water treatment system	$2,000 - $6,000	$200 - $600

The Executive member's additional 2 percent annual reward on qualifying Costco services purchases stacks on top of the 10 percent Shop Card — generating a combined return of approximately 12 percent on the project value for Executive members who qualify for both programs. On a $15,000 HVAC project, this combined return is approximately $1,800 — a meaningful reduction in the net project cost even if the project price itself is not discounted at the point of sale.

HVAC: The Most Commonly Used Costco Home Service

Costco's HVAC program — administered through its partnership with Lennox, one of the country's most established HVAC manufacturers — is the most frequently accessed Costco home service and the one with the broadest geographic coverage.

The Lennox partnership delivers Lennox heating and cooling products — furnaces, central air conditioners, heat pumps, and air handlers — installed by Lennox-certified technicians through Costco's regional partner network. The free in-home consultation is the starting point: a Lennox representative visits the home, evaluates the existing system, assesses the home's heating and cooling needs, and provides a specific system recommendation with installation pricing.

The HVAC consultation's additional practical value: the Lennox representative can identify system inefficiencies that may be costing the member money in utility bills beyond the comfort concerns driving the consultation. A home that runs a 20-year-old system at declining efficiency may be spending 30 to 50 percent more on monthly heating and cooling than a new energy-efficient system would require. The consultation surfaces this efficiency calculation alongside the replacement cost, providing the complete financial picture of the replacement decision.

The HVAC service covers the full range of heating and cooling needs:

Central air conditioning — replacement or new installation, sized to the specific home square footage and climate zone.

Furnaces — gas, electric, or dual-fuel, with AFUE efficiency ratings that are specifically relevant to the heating cost calculation in cold climate markets.

Heat pumps — the system type that has gained the most attention in the energy transition conversation, providing both heating and cooling from a single system with higher efficiency in moderate climate zones.

Indoor air quality — air filtration, humidification, dehumidification, and ventilation systems that address specific air quality needs including allergies, humidity control, and VOC filtration.

The 10 percent Shop Card on qualifying HVAC purchases and installation makes the Costco-partnered Lennox installation a meaningful financial consideration against competitive HVAC bids — even if the installed system price is comparable to competing quotes, the 10 percent post-project Shop Card reduces the net cost and the Shop Card is redeemable at face value for warehouse purchases.

Solar: The Largest Single-Project Opportunity in the Home Services Portfolio

The Costco solar program — administered through its partnership with Sunrun, the largest residential solar company in the United States — represents the category where the 10 percent Shop Card delivers the most absolute dollar value, because solar system installations are the highest-cost project in the home services portfolio.

A typical residential rooftop solar installation ranges from $15,000 to $35,000 before incentives, depending on the home's electricity consumption, the roof orientation and size, the specific panel technology selected, and the local installation market. A 10 percent Shop Card on a $25,000 system is $2,500 in Costco credit — a sum that, for an active Costco household, represents several months of warehouse spending at no additional cost.

The solar decision involves additional financial dimensions that the Sunrun consultation will address:

Battery storage — the optional addition of a Sunrun Brightbox battery (or equivalent storage system) that stores excess solar generation for use during evening hours or grid outages.

Battery storage adds $8,000 to $15,000 to the system cost but is eligible for the same 10 percent Shop Card treatment, making the combined Shop Card on a solar-plus-battery system potentially significant.

State solar incentives — many states offer additional solar incentive programs (net metering credits, state rebates, property tax exemptions on added home value from solar) that are additive to the federal solar Investment Tax Credit. The Sunrun consultant can identify the specific incentives available in the member's market.

The federal solar Investment Tax Credit — as of 2026, the ITC provides a credit of 30 percent of the solar system cost against federal income tax liability. This federal credit applies to systems installed through Costco's Sunrun program on the same terms as any other residential solar installation — the 30 percent credit is calculated on the full system cost before the Shop Card is applied.

For a homeowner planning a solar installation, the financial case for using Costco's Sunrun program versus booking Sunrun or a competing installer directly rests primarily on the 10 percent Shop Card — which is unique to the Costco member relationship and is not available through direct Sunrun installation bookings.

Windows and Doors: The Infinity from Marvin Partnership

Costco's window replacement program partners with Infinity from Marvin — a premium window manufacturer whose fiberglass window products carry specific durability and energy efficiency credentials that distinguish them from entry-level replacement window alternatives.

Infinity from Marvin's product line spans windows in every shape and size — including fixed, double-hung, casement, awning, bay, bow, and specialty shapes — along with patio doors in folding, swinging, and sliding configurations. The fiberglass frame material provides dimensional stability across temperature extremes that vinyl frames do not match, and the energy efficiency ratings of the Infinity window line support both comfort improvement and utility cost reduction in the homes where they are installed.

The window replacement service is not available at every Costco location — the program's geographic coverage is expanding but not yet universal. Members should verify availability in their market through Costco.com before planning around it.

The financial case for Costco's window program relative to independent window replacement contractors: the 10 percent Shop Card, the quality commitment of the Infinity from Marvin product, and the institutional vetting of the installation partner that the Costco relationship provides. Window replacement projects are one of the home improvement categories where contractor quality variation is most consequential — a properly installed premium window performs as warranted; an improperly installed window regardless of quality develops sealing failures over time that negate the efficiency investment.

Cabinet Refacing: The Reborn Cabinets Partnership

Kitchen cabinet replacement — removing existing cabinets and installing new ones — is one of the most disruptive and most expensive kitchen renovation approaches. Cabinet refacing — applying new exterior veneers, drawer fronts, and hardware to the existing cabinet boxes — delivers the visual transformation of new cabinets at approximately 50 to 70 percent of the cost of full replacement, with significantly less installation disruption.

Costco's cabinet refacing program partners with Reborn Cabinets — a California-founded cabinet refacing specialist with national presence through its Costco partnership. The Reborn Cabinets free consultation begins with an in-home assessment of the existing cabinet boxes — confirming that the structural elements are sound enough to support refacing rather than replacement — followed by a material and style selection consultation that produces a specific project estimate.

The 10 percent Shop Card applies to qualifying Reborn Cabinets projects booked through Costco — making the Costco-partnered cabinet refacing program the most financially compelling version of this service for members planning a kitchen update.

Each service includes a free in-home consultation with no purchase obligation. The consultation is the appropriate starting point for any member considering a home improvement project in these categories — the Costco-partnered specialist provides the project assessment, the system recommendation, and the specific pricing that allows comparison against independent contractor quotes.

How to Access the Home Services Program

The access pathway is consistently Costco.com → Services → Home Services. From the home services landing page, members can:

Browse the available service categories and confirm geographic availability for each service in their specific market.

Initiate the free consultation request for any service of interest — entering the property address, basic project information, and contact details. The Costco-partnered service provider contacts the member within one to three business days to schedule the in-home visit.

For members considering multiple services simultaneously — a solar installation combined with a window replacement, or an HVAC upgrade combined with an air quality system — each project is processed separately through its respective partner, with a separate Shop Card for each completed project.

The Executive member's 2 percent annual reward accrues on qualifying Costco services purchases — which includes qualifying home services booked through Costco's partner program. Confirm with the specific service partner whether the purchase qualifies for Executive reward accrual at the time of booking.

The Honest Assessment: When Costco Home Services Is the Right Choice

The Costco home services program is most commercially compelling when:

You are planning a major home improvement project in a category covered by the program and the project cost is substantial enough that 10 percent back is meaningful in absolute dollar terms.

You value the contractor vetting that the Costco institutional relationship provides. Costco's partner contractors are pre-qualified, vetted, and operating under a service commitment that the Costco relationship enforces. For members who find the contractor selection and vetting process stressful, the Costco partnership provides a starting trust level that independent contractor search does not.

You want to capture the Shop Card and use it for warehouse purchases that you were planning to make anyway — converting the Shop Card into effective cost reduction on future grocery, pharmacy, and household supply spending.

The program is less compelling when:

The project is in a category not covered by Costco's partner network in your specific market.

Independent contractor bids come in significantly below the Costco-partnered partner's pricing — in which case the 10 percent Shop Card may not offset the price difference.

You have a specific brand preference or technical specification requirement that the Costco partner's product line does not accommodate.
