I am so pleased to give this company a 10 on 10 for superb support. The folks at City Gas handle things beautifully on a routine basis, but I was amazed--and very grateful-- when I needed almost immediate help. The 75 gallon hot water heater in my furnace room rusted out at the bottom and caused a bit of chaos to say the least. After I got the water shut off, I sent an "emergency" email to their info address - this was Sunday afternoon. The response was prompt and courteous. At 11 am the next day (Monday) two senior techs were on site to install a new unit - exactly the commercial model I needed. The furnace room was spotless when they left and the old unit was tucked in away in their truck. I have great regard for this kind of excellence!
