Pros
As a technician you have a company vehicle which you get to bring home at night. Often times your pay starts from when you leave the house and stops when you get home. They give each technician a work phone which can be used for personal use as well. It's a very relaxed place to work and you can learn a ton. Double time is payed for weekend work and time and a half for anything over 40 hrs. Commission is based on quoted sales which pays 2% of the sale.
Cons
Being on-call is terrible and you don't get paid unless you work, which is unlike many other companies on-call policy. Work can take place any day of the week and at any time which can be a drag. E-calls are also a pain and once on one you can't leave until the customer is up and running. This can lead to extremely long days (24+hrs).
