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 announced an $8 million seed round on May 8, 2024, led by The Engine.
- On August 24, 2026, Pascal featured at Yale Cooling Conference and ATMO Europe.
- Slavney targets pilot partners in 2027 and commercial deployment by 2029.
What critics are saying
- Pascal still lacks disclosed commercial pilots, so revenue depends on unproven 2027 partnerships.
- Magnotherm and MIMiC chase the same alternative-cooling manufacturers and partner channels.
- If durability tests fail, Pascal stays a lab curiosity and future financing collapses.
What makes Pascal unique
- Pascal's solid refrigerants run HVAC temperatures at low pressure with off-the-shelf components.
- Adam Slavney says the system avoids HFCs, propane flammability, and CO2 ambient drawbacks.
- The company already runs a three-door commercial cooler and lab benchtop demonstrator in Watertown.
