Gas Guys George is simply outstanding! I can’t thank him enough for his exceptional service. When we encountered a stuck natural gas pipe, he went above and beyond, providing kind guidance over the phone to help us detach the part ourselves, saving us the expense of hiring someone to come in person. He knew exactly what to do just from a few photos I sent him. His expertise and willingness to assist are commendable. I highly recommend Gas Guys George for his professionalism, knowledge, and generosity. A true five-star experience!

I reached out to Metro West Gas over Yelp.
