We have a single-family home built in the 1950s. The electrical outlet where our refrigerator was plugged in stopped working. Bob conducted a thorough review of all our outlets and upgraded them. He was careful to pick colors that matched each room’s decor and he explained how the reset switches worked. He also found a problem with the power supply to the furnace humidifier and fixed that. All of this in about two hours or less. Would recommend this company to anyone.
