Company Overview
About Gradient Comfort
Gradient Comfort makes window-unit heat pumps — plug-in, window-mounted heating and cooling systems that fit in standard window openings — specifically designed for the hardest decarbonization problem in the US: old multifamily buildings with no central HVAC infrastructure. The company received a $17.5 million DOE manufacturing grant to build a Detroit production factory capable of 100,000 units per year, and has deployed systems in New York City and Boston public housing facilities at scale.
Business Model & Competitive Advantage
The window-unit form factor is the key to Gradient's market: unlike central heat pump systems that require electricians, plumbers, and structural modifications, Gradient's window unit installs in minutes without professional installation, enabling building operators to electrify apartments one unit at a time without whole-building retrofits. This dramatically reduces the cost and organizational complexity of multifamily building electrification.
Competitive Landscape 2025–2026
Government housing authority adoption — NYC Housing Authority and Boston Housing Authority represent two of the largest public housing systems in the US — provides the highest-credibility reference deployments in the affordable housing market. In February 2026, Gradient launched Nexus: a building management product that aggregates data from deployed units for property managers, enabling predictive maintenance and energy optimization across entire housing portfolios from a single dashboard.
