My experience was very very bad. They fleece you. For flushing the water heater, they charged me $359 when others charge $125-$150. He flushed back into drainpipe instead of flushing it out. The technician was very RUDE, he made me sign for $359, and I am still not getting hot water for which I called- he did not perform any diagnostics. Never hire them -- they overcharge. For an expansion tank, they charge $400. Others charge $150. Be careful. Bad service.
