"Val and I spoke on the phone regarding my refrigerator that was leaking water from somewhere. He said he would be able come by between 12-3pm. I appreciated that he texted me with his ETA when he was on his way here. Arrived promptly, diagnosed the problem quickly, had to make a short trip to the Ace Hardware near me to get the correct size valve for the water line. Replaced the valve, tested it, working properly, all set! I'm very grateful that he was able to come out so quickly today and took care of the problem. Very nice serviceman.
