James' Plumbing replaced our old furnace, added an air conditioner, and installed a new water heater. Over a period of 3 days, James, himself, came by several times per day to get the work started and to check on the progress. He discovered several deficiencies in our old system and corrected them immediately. His employees were all respectful, wore masks, and always left the area clean. I recommend James' Plumbing highly.
