I'm very interested in what I call "blue collar services" companies, things like the very popular lawn care, HVAC, roofing etc all the way down to dryer vent clean outs and specialty construction. I hadn't thought to pursue a company that was part of a regional/national franchise, but I've recently come across multiple franchise opportunities that seem relatively attractive.

Can anyone share their good/bad experiences, things to consider or watch out for, how to evaluate a franchise business compared to a standalone business?

Thanks for any insight.
