Condensate leaks are one of the HVAC industry’s most persistent problems. For ductless heat pump installations, they account for 10-20% of all callbacks — disrupting homeowners’ lives, potentially damaging homes, and costing installers valuable time and money on return trips.
At Quilt, we refuse to accept industry pain points as inevitable. Our vertically integrated approach means we can design hardware and software solutions that address real-world challenges our partners face every day. That’s why we’re introducing a first-of-its-kind drill guide, along with backplate improvements and enhanced training resources, all designed to help our partners reduce condensate-related callbacks by 50%.
Why condensate leaks happen
In ductless systems, condensation naturally forms on the indoor unit’s evaporator coil during cooling. This moisture needs to drain properly through a small hole drilled in the exterior wall. When that drainage path isn’t perfectly angled for installs that rely on gravity to drain, or the unit isn’t level, water can back up and leak into the home.
It’s a deceptively simple problem with expensive consequences. For homeowners, it means water damage and disrupted comfort. For installers, it means callbacks that eat into job profitability and take time away from new installations.
Engineering solutions, not workarounds
Most heat pump manufacturers treat condensate issues as an installation challenge — something for contractors to solve in the field. We see it differently. If our partners are experiencing a recurring problem, our engineering and design teams view that as an opportunity to improve the product itself.
That’s why every Quilt Indoor Unit now includes:
- A precision drill guide that helps installers create the optimal angle for the drain hole. This single-use guide ensures proper drainage from the start, eliminating guesswork during installation. It’s the first tool of its kind in the ductless heat pump industry.
- Enhanced backplate stability with added structural features that keep the indoor unit perfectly level throughout its lifetime, preventing the subtle shifts that can compromise drainage over time.
- Clear labeling that reminds installers of critical best practices — proper drain routing, unit leveling, and drain testing — right at the point of installation.
Supporting partners beyond the hardware
Hardware improvements are just the beginning. We’ve also expanded our partner training with detailed drain installation guidance, and ongoing support from our team.
“I’ve been installing heat pumps for 15 years, and I’ve never seen an OEM put this much attention to detail toward the installer experience,” said Alex Sokolov on Quilt’s Install & Engineering Support team. “Working directly with our engineering team to design these solutions — that’s unheard of in this industry. These updates prove that Quilt doesn’t just listen to what we need in the field, we’re actually part of building the solution.”
Building for the long term
Even our consumable materials reflect Quilt’s commitment to thoughtful design. The drill guide and labels are made from recyclable materials, consistent with our packaging philosophy of eliminating styrofoam and reducing environmental impact wherever possible.
This launch is another example of how Quilt systems improve over time. Whether through over-the-air software updates that expand system capabilities or thoughtful hardware refinements based on real-world feedback, we’re constantly working to make our products better for both homeowners and the partners who install them.
The new condensate updates are now standard with all Quilt Indoor Units. For partners with existing inventory, the current indoor units can still be installed using best practices for drain routing — the new components are aids that make proper installation even easier.
