Shreyas Sudhakar joined the Building HVAC Science podcast to talk about his path from rocket propulsion engineering to building high-quality heat pump installs in California. Bill and Eric found him through his thoughtful LinkedIn posts, and Shreyas shared that a friend's relentless heat-pump evangelism finally pushed him to look deeper. Once he did, the tech clicked. He realized HVAC and rockets share the same core idea: moving energy through systems, and the math is not as far apart as it sounds.
What really pulled him in was the homeowner experience. After talking with homeowners on Nextdoor and Reddit, and even calling contractors for quotes himself, he kept hearing the same frustrations: heat pumps feel expensive, contractor advice is inconsistent, trust is low, and myths like "heat pumps don't work in the cold" still show up, even in mild California climates. Shreyas' view is simple: most homeowners do not care what the equipment is called. They care about comfort, noise, bills, and safety, and the best outcome is when the system is so reliable they barely think about it.
Shreyas now runs Vayu, a lean heat pump installation company operating with vetted subcontractor partners, while his Heat Pumped newsletter and podcast focus on education for homeowners, technicians, and policy folks. Vayu handles the end-to-end process, from load sizing and equipment selection to permits and rebates, while partner shops focus on the craft of installation. His definition of success is not just a happy install day, but a customer still loving the system a decade later, and technicians thriving because the model removes desk work and supports quality work at scale.
