Dahl Plumbing installed a forced air system in our home. I told the technician that I smelled gas, and he said it was normal. So I had PG&E come out and by merely tapping on two of the flexible pipe connections, they fell apart. PG&E found a total of 3 gas leaks.
Pros: initially friendly
Cons: gas leaks, different registers used than promised, rude
