Overview
Pascal develops solid refrigerant technology for HVAC, aiming to replace traditional gaseous refrigerants. Its solid-state refrigerants are designed to operate at the same temperature and pressure as gases and work by absorbing and releasing heat inside HVAC equipment, enabling heating, cooling, and hot water generation. Pascal differentiates itself by delivering zero global warming potential while maintaining conventional operating conditions, which can allow for smaller, more energy-efficient systems and a shift in how HVAC manufacturers and service providers approach cooling and heating. The company’s goal is to cut energy use and the environmental impact of the HVAC sector and lead the industry toward cleaner, scalable refrigerant solutions.

Simplify's Take
What believers are saying
- Pascal opened a Business Operations Manager role in Cambridge on May 13, 2026, signaling hiring.
- ATMO America 2026 reported a self-contained three-door cooler operating in Pascal's lab at 5°C.
- Pascal told ATMO America it targets about 20% better efficiency than equivalent R290 systems.
What critics are saying
- Pascal remains in development stage in June 2026, while Magnotherm already installs retail units.
- The company still has only an $8 million seed round, limiting buildout and certification.
- If Pascal misses 2026 commercial demonstration targets, incumbents will own the HVAC transition.
What makes Pascal unique
- Pascal's low-pressure solid refrigerants deliver HVAC cooling from -40°C to 60°C, unlike HFC systems.
- Pascal is PFAS-free and zero-GWP, eliminating refrigerant leaks that standard HVAC cannot avoid.
- Pascal's platform targets existing HVAC manufacturing and commercial coolers, not a new supply chain.

Pascal, a startup based in Cambridge, MA, has secured $8M in seed funding to advance its development of HVAC systems using solid refrigerants. The funding round was led by Engine Ventures, with participation from Khosla Ventures and Blindspot Ventures. CEO Adam Slavney plans to use the funds to commercialize their innovative, low-pressure system and expand the team. Pascal's technology promises up to 80% better energy efficiency, zero direct emissions, and compatibility with existing HVAC components.
CAMBRIDGE, Mass.--(BUSINESS WIRE)--Pascal, a startup developing high-efficiency climate-friendly heat pumps, air conditioners and refrigerators based on solid refrigerants, today introduced its novel technology and announced it has raised an $8 million seed round led by Engine Ventures, with Khosla Ventures and previous investor Blindspot Ventures participating. The funding will be used to productize Pascal’s low pressure, solid refrigerant-based system, conforming to commercial HVAC specifications. The company will also use the capital to expand its Boston-based team of mechanical engineers, chemists, and material scientists. Currently, space and hot water heating, cooling and refrigeration account for approximately 50% of electricity use in commercial buildings and over 70% in residential buildings. In addition to requiring substantial energy, today’s HVAC technologies – including heat pumps – rely on hydrofluorocarbons (HFCs), a group of synthetic gasses used for cooling and refrigeration. HFCs’ impact on global warming can be thousands of times greater than that of carbon dioxide, with an estimated 2% of total greenhouse gas emissions coming from HFC leaks from HVAC systems
