He fixed our LG fridge that had a leak in the valve in the water line at the back of the fridge. It had been repaired 3 weeks ago by another company that did not warranty their work. ATTA looked at it & knew what the problem was immediately (the other company had used the wrong kind of valve) & fixed it by replacing with the right valve. He was very polite & came out within 2 hours of me calling him. I highly recommend ATTA.
