You wouldn't need an HVAC per hive, but rather 1 HVAC for the swarm. Get a water mass, HVAC it to the right temperature, and then pump the water through the hives to maintain a good temp.
It'd be somewhat more expensive and you'd have to have enough insulation to make sure the water isn't prematurely cooling before reaching the hive.
Hives also tend to be really cheap. They are simply wood boxes. So you'd be competing with $100 wood box with $200 wood box and $1000 HVAC and plumbing.
IIRC they are _massively_ less efficient. Relevant Technology Connections video: https://www.youtube.com/watch?v=CnMRePtHMZY

Lots of cool tech from the past
Who benefits most from old methods and tech remaining a historical footnote, but the very people selling their new whiz-bang solutions for modern problems, which are themselves inherent to using their products and energy production and consumption supply chain?
