Vantaggi
If you love HVAC, this might be a good fit - You will be able to build connections throughout the entire industry in quite a large region of the east coast. If your career goal is to become a salesman or a sales engineer, you will most likely be presented the opportunity (with sufficient work history & experience at this company or similar) to rise into that role and make a very hefty sum of money. Company culture is pretty good, excluding management/supervisors and compensation structure transparency (which is, admittedly, a big deal), and you will likely meet and befriend a number of coworkers. The company hosts lots of social events in and out of work hours.
Svantaggi
That being said, there are issues. The work-life balance is not incredible, and you should expect to take work home with you. The work can be pretty monotonous. Work intensity is inconsistent - Some weeks will be incredibly lax, but busier weeks (especially when your department or the company is undergoing change) will be nearly unmanageable. Support from supervisors and management can be lacking, and depending on your department and time of hire, it can be very dismaying. You will learn a good bit about HVAC equipment, design, and the workings of the industry, but many of the skills you will spend your days learning and refining are incredibly niche and specific to this job. Expect to put lots of energy into learning software that you will not use in future jobs. Incentive structure is not closely tied to the performance of employees in non-sales roles - Expect a big chunk of your pay package to be vested in a bonus. For many roles, management will determine a maximum yearly value of the bonus and devise (unbeknownst to the employees) some sales-related metric that they want the department/company to meet, and you will get some fraction of that maximum value paid to you annually (prorated) based on your department/company performance. You may work incredibly hard in a year and have very little sway on your incentive.
