Ron converted our home from propane to natural gas and converted our range and furnace back to natural using original parts which I retained. He designed a system using properly sized piping with pre -installed tees and values that will allow for additional ng appliances which will save us a lot money. He even recommended the the right size gas meter. All his work was done promptly, cleanly and professionally. Best of all his estimate several hundreds of dollars less than a big name competitor.
