Master Services's salesman mentioned Master Services's rating with Angies List. Well, there are millions of people that do not consider anyone on Angies List; me included. My decision to go with Master Services was the reference of my HVAC guy.
My HVAC contractor was aware of my situation and told me he'd call a company that he knew would do a good job. About 2 weeks later, Master Services called me and mentioned my HVAC guy and I set up an appointment.
