diagnosing a furnace is my gas leak tester I bought at Johnstone supply for about $175. This tester finds leaks in valves that are almost impossible to find with soap bubbles. It is much faster, cleaners, and more effective.
Most often, the customer cannot smell a gas leak and if they can't smell the leak, it is not serious to them. When they hear the siren of the gas tester squealing there is a better confirmation that a serious problem exists.
