Quilt Solves Most Expensive Heat Pump Installation Problems with New Features, Including First-of-its-Kind Over-the-Air Update
New product updates fix crossed wires in 10 minutes remotely and cut condensate leaks in half, saving contractors costly return visits
Quilt, the smartest way to heat and cool your home, today announced two industry-first updates that make its heat pumps more effortless to install. First, Quilt can now correct crossed wires on eligible installs with an over-the-air software fix, a completely remote repair without a technician needing to be on site. The company also released a precision drill guide for Quilt Indoor Units that helps contractors create a more accurate condensate drain hole, effectively reducing condensate leaks by 51%. Both greatly decrease callback visits, each of which cost installers $450$600 USD in labor, mileage, and lost business opportunity, and amount to tens of millions of dollars per year.
These releases build on Quilt Tools, the recently launched software platform that lets homeowners grant installers proactive alerting and remote diagnostics without having to be physically present. Together, the new features power a smart energy system that solves installation errors early: fixing them with software that improves over time, and preventing them with thoughtfully designed hardware.
“Every installation issue is time, energy and money that a contractor didnʼt plan for,ˮ said Bill Kee, co-founder and Chief Product Officer of Quilt. “Weʼre addressing the most common callbacks installers face with smarter software and hardware. If every ductless install were Quilt, we would save the industry tens of millions of dollars and free up time and labor for other jobs.ˮ
Crossed wires, fixed with software
On a multi-room ductless install, every indoor unit connects to its own port on the outdoor unit. If a wire lands on the wrong socket, the system canʼt control the right room. It is a common, hard-to-spot mistake for the industry, and usually requires a return appointment.
Quilt now solves eligible port mismatches remotely with a software update. Quilt Tools detects the crossed wire before the homeowner or partner notices, and sends a corrected wiring map over the air. The unit checks that it matches the physical setup, then applies the new map. The whole process takes under 10 minutes from alert to fix, and relies on Quiltʼs extensive system telemetry and cross-device communication.
When paired with Quilt Tools, which automatically flags crossed-wire issues to contractors, it becomes an entirely hands-off solution. Quilt handles it remotely, the crew keeps its schedule, and the homeowner never sees a second visit. For legacy HVAC manufacturers without software-first systems, this kind of repair would be impossible and call for another truck roll.
“We finished a multi-room install and that evening, Quilt Tools flagged crossed wires on the system. Normally thatʼs a callback: the homeowner is frustrated, we pull a tech off another job, and we lose half a day driving out and rewiring,ˮ said Mike Anderson, President and CEO at West Coast Heating Air and Solar in California. “This time, Quiltʼs team fixed it remotely in literally minutes. The homeowner never had to call us, and my crew never had to go back.ˮ
The crossed-wire solution has been rolled out to every Quilt system in the field through an over-the-air software and firmware update, joining recent releases like Dry Mode and Capacity Expansion.
Condensate leaks, cut in half
When a ductless heat pump cools a room, moisture collects on the indoor unitʼs coil and drains outside through a small hole in the exterior wall. If that hole isnʼt angled correctly, or the unit sits slightly off level, water can leak into the home and damage walls.
Condensate leaks account for 10% to 20% of all ductless heat pump callbacks, and the industry usually treats them as an installer problem.
Quilt approached it as a design problem. Working directly with Quilt Certified Partners, Quilt engineers found that drain line angle and routing were the single largest driver of leaks, and built the fix into the product. Every Quilt Indoor Unit now includes a precision drill guide that sets the right angle for the drain hole, the first tool of its kind for ductless heat pumps. Along with a more stable backplate to keep the unit level, and more labels reminding crews to check drainage before they leave, the improvements have cut condensate leaks by 51% between the 2025 and 2026 cooling seasons, saving Quilt Certified Partners $450$600 USD for every eliminated callback.
“Condensate leaks are one of the most dreaded callbacks on a ductless install. If the wall penetration isnʼt pitched right, water backs up behind the indoor unit and runs down the inside of the wall. By the time the homeowner notices, youʼre fixing the drain line and the drywall,ˮ said Ryan McLennan, Sales Manager at GreenSavers in Oregon. “Quilt’s drill guide takes the guesswork out of the line set hole. We get the angle right on every install, and we havenʼt had a single leak callback on a Quilt install since we started using it.ˮ
A heat pump that keeps getting smarter
Most major HVAC manufacturers are a century old, and their ductless equipment is built on static hardware that depreciates as soon as itʼs on the wall. Quiltʼs software-first system continually learns from the field, flags issues through Quilt Tools, fixes errors as they happen, and gains new capabilities through over-the-air updates. This is only possible because of Quiltʼs dedication to smart software and intentional design, and building a brand new energy system from the ground up.
“For over 100 years, HVAC has been a box you install and hope for the best,ˮ said Paul Lambert, co-founder and CEO of Quilt. “Weʼve created an integrated, ever-evolving system that is redefining how homes heat and cool, and helping power the energy transition now and into the future.ˮ

About Quilt
Quilt is building the modern home energy system, starting with HVAC. It is the largest energy load in the house and the system people touch every day. Quiltʼs first product, a ductless heat pump, is the smartest way to heat and cool your home. With industry-leading SEER2 and HSPF2 ratings it is 20% more efficient than comparable ductless heat pumps, and it pairs that performance with sleek, architectural design, intuitive room-by-room control, real-time energy usage tracking, and radar-based occupancy detection.
Quilt is a software-defined system: every unit is connected, instrumented, and updatable over the air, so performance improves after installation rather than degrading. That architecture is protected by a portfolio of issued and pending patents spanning hardware design, software control, and distributed system architecture. Quiltʼs Certified Partner network, built from zero starting in 2025, now spans more than 200 partners across 46 U.S. states and Canadian provinces, a channel built to compound and to carry every future Quilt product to market. Monthly installs grew over 5x in the first half of 2026, and the company maintains a customer satisfaction score of 4.7 out of 5.
