I called 3 fireplace companies about my leak - this is the only company who actually came out and fixed the gas leak. Royal Chimney charged me $279 for cleaning, but refused to start up the fireplace or check the gas leak. They didn't even have a gas leak tester. American Heritage was honest and upfront about their costs - $149 to come out and the charge of the switch, which was $60. The technician came out, replaced the gas valve, checked for gas leaks after turning on the gas line switch and then lit a fire. He turned it off and showed me how to operate the switch too. Great company, great service, reasonable cost. I'll hire them anytime for more work.
