Very Courteous




Review of Grassers Plumbing and Heating

The young gentleman who came to my house to check my furnace was extremely pleasant, explained what he was going to check for, discovered an issue with a piece of pipe that connected to another pipe and fixed everything in a timely manner. He also inspected the thermostat and explained that it had batteries which were due to expire, luckily I had the batteries on hand and all is well with my system. I am very happy with the service call and the price was much lower than I expected!
