Because they know you can't be without water and your scared your pipes can burst. Well no plumbers wanted to do n this cor available except Greenlight. They charge nothing to come out and diagnose your issue and tell you what it will take to fix this. Within 20 min they had a price that considering it was a big job to fix was reasonable. Within 1.5 they had my water running and considering all the labor and parts. Thank you for giving me a senior discount and your professionalism.

I called and person on call was in Yarmouth and it will take time. I told him no rush. He then called me and said his supervisor said it will cost $ 700 to come and I said your kidding and said don't come. I wrote a review in Yelp and a few minutes later manager of high efficiency appologized many times saying on call did not know situation and he will send over one of his workers. The worker came over and replaced a piece. I removed my review and now received the bill charging me $ 600 dollars ( labor) for visit. I paid by credit card but complained because i cancelled on call and spoke to I believe was a manager at High Efficiency. They offered a $ 100 dollar credit but not on my credit card but instead a $ 100 credit on a future overcharged invoice. Beware of this company.
