U.S.-based sustainable home heating and cooling company Quilt has raised $20 million in a Series B funding round to scale sales of its next-generation heat pump systems and broaden market reach across residential and commercial segments. The fresh capital will be used to expand the company’s go-to-market operations, grow its field and installation teams, and accelerate product development focused on affordability and climate impact. Founded in 2021, Quilt designs and manufactures high-efficiency air-to-water heat pumps that provide heating, cooling and hot water with significantly better energy performance and lower emissions than traditional fossil-fuel systems. The company’s technology aims to make heat pumps more accessible in the U.S. market where adoption has lagged due to cost, installation barriers and product complexity by simplifying installation and integrating intelligent controls that optimise performance and reduce homeowner energy costs. The Series B round was led by Congruent Ventures, a climate tech-focused VC firm, and included participation from Prelude Ventures, Builders VC, Ulu Ventures, Powerhouse Ventures, existing backers Carbon Collective, Congruent’s Syndicate Partners and strategic energy investors committed to scaling decarbonisation technologies. The new funding brings Quilt’s total capital raised to $40 million+ and positions the company for rapid growth as policies and incentives including federal and state clean energy programs continue to support heat pump adoption across the U.S. Quilt co-founder and CEO David Dufty said the company will deploy the funding to expand its sales footprint, accelerate hiring in engineering, operations and field services, and continue investing in product enhancements that reduce installation costs and improve reliability. With climate goals placing greater emphasis on building electrification, heat pumps are increasingly viewed as a crucial lever for reducing carbon emissions in residential and commercial buildings. The company’s products designed for ease of installation alongside local HVAC partners are already deployed in multiple U.S. states, and Quilt plans to deepen relationships with distributors, utilities and contractor networks to drive broader adoption. The Series B financing will also support supply chain scaling and inventory expansion to meet growing customer demand. #ClimateTech #HeatPumps #CleanEnergy #Quilt #SeriesB #SustainableBuildings #Decarbonization #HomeEfficiency #EnergyTransition #ClimateAction #GreenTech #BuildingElectrification #TechFunding
