I was very offended by the quote I received from Peterson for this installation. I requested a ball park estimate over the phone and would not have had the serviceman come to my home if I had been given an estimate beforehand. What a rip-off! I wasted my time and $50 obtaining this insulting quote. I got a quote from a competitor for a third of the price. My dad was so disgusted by the quote that he drove over from Denver to help me out. It took us a few hours and cost less than $100. The quote I received prior to the phony "multiple service" discount was $1500. Completely appalling. I will not recommend Peterson to anyone. After sharing my experience I have heard countless stories. Not sure how Peterson is in business, I assume by getting jobs from people who are desparate and don't know any better.
