Frequently asked questions
General
If there’s a Quilt Certified Installer in your area, we’ll connect you with them to get started. We’re working as quickly as possible to expand our service regions and bring Quilt to more homes, so if we’re not available yet, we will be soon! Sign up for our newsletter at the bottom of this page to stay up to date with all things Quilt.
Our mission is to accelerate the energy transition for everyone. If you’re interested in partnering with us to help Quilt grow, please contact us.
Quilt’s modular design is a good fit for entire homes, partial homes, and one-room configurations, including ADU’s. Single-family homes with exterior walls are the ideal fit for Quilt because they allow space for an efficient configuration of outdoor and indoor units. If you have specific questions about how Quilt could work with your space, contact us here.
Quilt is only available for installation through a trusted Quilt Certified Installer in your area. Our partners are trained to ensure top-quality installation and service, which is essential for optimal performance and long-term reliability.
Your Quilt Certified Partner will work with you to design the right system for your comfort needs. We typically recommend one indoor unit per room or living area. For some larger spaces, adding a second indoor unit may provide more comfort. Once our suggestion based on your address appears, you can then adjust your configuration before placing a reservation. Your installation partner will then walk through your home details in even more detail and adjust your configuration further as needed.
To get started, check availability in your area and connect with our Quilt Certified Partners at Quilt.com
If you have questions about how to use your Quilt system or need help troubleshooting, we’re here to help. Quilt.com/support has detailed instructions for cleaning, maintenance, troubleshooting, and temperature sensing — along with our support contact information, User Manual, and Quilt Start Guide.
We’re well-established, well-funded, and built for the long haul — but we also believe in thinking ahead, so here’s an honest answer.
Quilt is designed on durable foundations. That means your comfort isn’t contingent on our servers staying online. A software update rolling out soon will allow the Dial Thermostat to communicate directly with your indoor unit over your home Wi-Fi network — no internet connection required. So even if your internet goes down, you stay in control as long as your Wi-Fi is running.
Your indoor units also have IR receivers, which means they can be operated by any standard universal mini-split remote if Quilt ever ceased to exist. You’d have fewer smart features while retaining full basic temperature control. And because Quilt is built on standard heat pump technology, any qualified HVAC technician can service your system the same way they would any other HVAC equipment — no proprietary service required.
We also back every system with up to a 12-year warranty on parts and compressor for the heat pump system, and a 3‑year warranty on the Dial and QSM — with no registration required. That’s not a short-term commitment.
And in the unlikely event we ever did sunset? We’d go out responsibly with a final “offline-complete” firmware update that would keep your system functional without cloud services. Our repair manuals and hardware documentation would remain publicly accessible, so your investment is never stranded.
Quilt is built to last — and so is your home comfort.
Installation
Quilt is installed by our trusted Quilt Certified Installer, who are trained to ensure top-quality installation and service for the best performance and reliability.
In most cases, there may be only one Quilt Certified Installer available in your area. Our partners are trained to ensure top-quality installation and service, which is essential for optimal performance and long-term reliability. If multiple installers are available, we select the best fit for your home based on your system design, location, and installer capacity.
Installation typically takes between one and three days, depending on the number of units being installed in your home. Your dedicated installation partner will be able to offer a more specific timeline once they have a better understanding of your home.
On day one, your installation team will perform a full walkthrough of your home to confirm the right placements for the indoor and outdoor units. Next, the team will install the line sets that connect the indoor units to the outdoor units. Once connected, the units will be pressure tested. Now that the system is in place, the team will install your Dials exactly where you want them. Once the system is up and running, the team will help you familiarize yourself with your Quilt.
During installation, an indoor unit is mounted to one of your exterior walls. A 3‑inch hole is drilled through the wall, which connects the unit to the line set, condensate drain, and wire that power it. This line set runs outside your home to the nearest outdoor unit and is hidden in a line hide. You can work with your installation team to determine the line set placement to balance both aesthetics and proximity.
Quilt’s outdoor units are labeled 208⁄230 VAC, 60 Hz. The minimum circuit ampacity is 13.2 Amps, and a 20 Amp circuit breaker is sufficient.
We offer over-the-air updates, automated system maintenance, and diagnostics reporting to keep everything up and running. You can always email [email protected] with any questions or issues.
For Certified Partners: 10-year warranty on parts and compressor for the heat pump system, 3‑year warranty on the Quilt Dial and QSM. The warranties are transferable to the next homeowner, and no registration is required.
For Select and Expert Partners: 12-year warranty on parts and compressor for the heat pump system, 3‑year warranty on the Quilt Dial and QSM. The warranties are transferable to the next homeowner, and no registration is required.
If you replace your furnace with a Quilt, not only will you be taking a meaningful step to reduce your home’s reliance on fossil fuels, but you’ll also be gaining back square footage of your home. Your old furnace or heating system can be removed, and if you have ducts, they can be sealed off. Your installation partner can discuss with you the best options for your home.
Pricing & Rebates
Quilt is priced in line with other high-efficiency heat pumps on the market — but what you get with our smart technology goes well beyond what those systems offer. Because every home is different, pricing is customized to your system design. After a consultation or site visit, your local Quilt Certified Installer will provide a detailed, tailored quote that includes both our products and their installation labor.
For a rough estimate of installation costs before you get started, third-party resources like Rewiring America offer helpful benchmarks. Your exact costs will depend on your home’s setup and local labor rates, which vary across the country.
There are many types of rebates available. Some depend on your new configuration, the old system you’re replacing, and certain details about your home. As the most advanced and efficient ductless heat pump, Quilt qualifies for the maximum amount of rebates available. Ask your Quilt Certified Installer about rebates in your area.
Financing options vary by installer. Your Quilt Certified Installer will provide details on the options they offer.
If you purchased a heat pump through Quilt, you may be eligible for federal tax credits under the Inflation Reduction Act. To claim these credits on your tax return (Form 5695), you’ll need the Qualified Manufacturer Identification (QMID) for your equipment. Quilt’s QMID is L6F3 to use when completing IRS Form 5695 to claim your heat pump tax credit.
Hardware
We’ve sized our outdoor units to power up to three indoor units, a ratio that delivers the right mix of efficiency, control, redundancy and modularity. Smaller outdoor units like ours are more compact, quiet, and efficient than larger units, ultimately saving homeowners energy and money. When installed in a full home, they also more completely deliver on the promise of room-by-room control, enabling some rooms to be heated while others are cooled, which can’t be done with one large outdoor unit. The flexibility of smaller systems also means that they give full homes the benefit of the redundancy of multiple outdoor units, while also making it possible to install Quilt in one, two or three rooms, then expand to full home coverage over time.
Quilt delivers its full heating capacity at outdoor temperatures down to ‑5°F, and 90% of its heating capacity down to ‑13°F. For 94% of the country, that is as low as the temperatures typically get. For those who live in even colder climates, there are other heating systems that may be more efficient.
As the most advanced ductless heat pump, Quilt sets a new efficiency standard with industry-leading SEER2 and HSPF2 scores for residential climate control. In California, Quilt also meets Title 20 and 24 Energy Requirements. To learn more about our industry-leading efficiency, see our tech specs.
System sizing — the number of indoor and outdoor units recommended — is determined by the unique characteristics of your home. These include, but are not limited, to:
- Insulation level of floors, walls, and attics
- Insulation level and air-tightness of windows and doors
- Amount of glass in the space and exposure to sunlight
- Average ceiling height
- Number of exterior walls in space
- Physical layout of each room and other connected spaces
- Average number of occupants in each space
Your local Quilt Certified Partner will spend time analyzing your home to determine the right system size and installation plan for your home based on the factors above.
Most rooms will be able to be conditioned by one Quilt Indoor Unit, but variability in room size, home size, and regional climate may impact the kind of system configuration that works best.
In California, our general guidance is that a single indoor unit can effectively condition up to 480 sq. ft. of space, while larger or more open rooms would be better conditioned with a second unit. In locations with more extreme climates, rooms may benefit from an additional indoor unit. Your local Quilt Certified Partner can work with you to design the perfect system for your home.
For homes located in areas with temperate weather conditions, one Quilt Indoor Unit efficiently and effectively conditions an average room up to 480 sq. ft. For larger rooms, or rooms with characteristics that tend to require more heating or cooling, a second indoor unit will ensure that the space is always at your optimal temperature.
When two indoor units are installed in one room, they operate in tandem to reach your set point. Both are easily controlled together in the Quilt app and on your Dial. They each will operate more quietly, run more efficiently, and create a more even temperature compared to a single or larger unit working to condition the full space.
Quilt’s heat pump system is variable speed, which means it can turn down to low operating capacities to condition smaller rooms efficiently and quietly.
Yes. Quilt supports a supplemental temperature sensor that works seamlessly with your Quilt system to deliver room-by-room precision exactly where you need it.
Perfect temperature control requires perfect temperature sensing. While Quilt Dials deliver exceptional accuracy in most installations, some homes need a different approach to achieve optimal comfort. Our supplemental temperature sensors can work alongside your Dial or replace it entirely where installation isn’t ideal.
Whether you’re supplementing existing Dials or using sensors as your primary temperature control, you get the same intelligent, responsive heating and cooling experience. These sleek, wireless sensors give you maximum flexibility to create the perfect climate solution for your home — no compromises on placement, no required electrical work, no barriers to comfort.
Talk to your Quilt Certified Partner about incorporating sensors into your system design.
Quilt is designed in California and manufactured across Vietnam, China, and Malaysia — and there’s an important distinction worth making here.
Quilt is not a white-labeled product. Every detail is custom-designed by our team — from our proprietary software stack to the hardware itself — and we work closely with best-in-class manufacturers to bring that design to life. Our heat pump hardware is developed through a joint development agreement with one of the leading heat pump manufacturers in the world — built to our specifications, not theirs. Our smart devices are built by a team that produces some of the most recognized smart home products on the market. Partnering with established manufacturers at this scale also means a reliable, resilient supply chain — so your system arrives on time and as expected.
One of the biggest barriers to heat pump adoption is up-front cost. Manufacturing overseas is how we keep Quilt affordable without compromising on quality or innovation. We also partner with manufacturers across multiple countries — a deliberate choice that gives us additional supply chain resilience in a shifting global landscape.
We take the same quality obsession we bring to our U.S. operations into every aspect of those partnerships. That’s not a talking point — it’s how we vet, manage, and hold our partners accountable.
