About Rensair

Rensair is a UK-based startup established in 2020 that aims to revolutionize the HVAC industry with the world's first certified air quality ecosystem. The company's slogan "HVAC: Hacked. Cutting carbon, costs and pollutants with the world’s first certified air quality ecosystem" succinctly captures its mission. Rensair addresses the significant environmental impact of HVAC systems which account for 16% of global carbon emissions. Despite this, indoor air quality can be up to five times worse than outdoor air. Rensair has developed a certified air quality ecosystem that not only reduces carbon emissions and energy use by over 40% but also purifies indoor air, creating healthier environments. This innovative approach not only tackles the climate crisis but also supports cost savings, making it an appealing solution for large corporations striving to meet their ESG and Net Zero commitments. The company recently secured a Series A investment on 13th April 2023 from Alumni Ventures, underscoring investor confidence in its potential to disrupt the HVAC and environmental technology space. The industries Rensair operates in include Health Care and Manufacturing, reflecting the diverse applications of its technology. The startup's commitment to sustainability and environmental impact aligns with global trends, presenting an attractive opportunity for investment in the green tech sector. Rensair's advancements in addressing both environmental and health concerns through its HVAC innovation position it as a noteworthy contender in the market, with potential for significant growth and impact.
