Don't do business with Beacon Plumbing! They replaced a high-limit switch on my gas furnace and charged me $307, plus a $100 service charge.. It took one minute to remove two screws and plug it in, and I found out later that the part costs less than $20. When I contacted them about the inflated charge their reply was "we don't work by time and material and use flat-rate pricing". I forgot to mention that the Better Business Bureau has them rated a C- for 69 complaints filed against them in the past three years.
