I'm in diligence of an attractive B2B HVAC and Refrigeration company (B2B; not cyclical; maintenance contracts); however, I'm concerned that I do not have an engineering or technical background. Does anyone have experience buying and operating a company where they would be 100% reliant on their workforce to deliver technical service to clients?

Additionally, recruiting a blue collar, skilled workforce is challenging. I'm interested to hear about anyone's experience recruiting such talent.

Thank you in advance for any thoughts
