A gas hot water heater was spilling carbon monoxide into the utility room. Russ Technician 1032 came out, found that a bag of nails and a log of all things were stuck in my chimney. He recommended getting a chimney sweep, and coordinated with chimney sweep's arrival time, and reconnected the gas appliance.
Pros: Fast reliable service
Cons: Reasonable rates, but plumbers do cost money.
