Nathan Lenahan and two partners just bought an HVAC business. In this interview, Nathan lays out what is so appealing about HVAC, which is a business you hear a lot about in the SMB acquisition world. Also, Nathan and his partners bought small. This was a $400,000 acquisition, not very big — counter to the advice you've heard from other Acquiring Minds guests who say you should buy as big as you can. But Nathan already sees a path to very strong growth in the first year of ownership. So even though they bought small, he and his partners may have a considerably larger business in a relatively short amount of time. Anyway, Nathan knows a lot about home services, and now I finally know something about HVAC. And you will too, after this interview with Nathan Lenahan.
