Vantaggi
The people who you will work with are typically great people (except management). You will get very close to each other, in some cases knowing as much about their families as they will of yours. Great moral support because of that.
Svantaggi
No loyalty to long time employees or long time customers. They treat all customers one way: with dollar signs pinned to their forehead. Would rather just sell a new system no matter what the age of the equipment rather than do what is right for the customer. New management has no reality of how big of a mess this company is in, and refuses to tell the truth to the employees of how truly bad it is. Upper management believes that hiring new people who have no back round in HVAC is the way to do business, especially in management roles.
