I needed a gas line installed (for a gas cooktop) and contacted a few companies. Frank promptly returned my call, and offered me the lowest price. (This price held true, and I wasn't left with any surprises.) Not only was he at my home within a few days, but he arrived at the exact time he said he would. He was very polite and amiable. I was very comfortable having him in my home. He had to drill a hole to run the line, and cleaned up the dust himself. I could not be more satisfied with the level of service GTA Gas Systems provided, and will absolutely recommend Frank every chance I get.
