I have used RM Mullinix for quite some time now and I have nothing but great things to say about them. I especially appreciate the service guys who have been coming out to my house for the last two years. The company had sent out a salesman, but he wasn't the one who finally swayed us to purchase an entire unit, that credit goes entirely to the service guys. I am not saying anything negative about their sales staff, I just want to say it was the service people who closed the deal. Everything turned out fine, the unit works and I continue to use their service to this day.
