Pricing very reasonable. Very dependable and amicable. Highly recommended."

"Used this company previously and again it was a pleasure from beginning to end. I would give him 10 Stars if I could. Referred William to a close friend of mine and she was just as pleased. We both sleep better during our bad Florida thunderstorms. A friend of mine lost their home due to lightning. They got out just in time couldn’t save anything but their lives barely. I urge all to install lightning rods."

"Very professional and efficient. Arrived timely, very knowledgeable, and efficiently repaired appliance. Our General Electric large refrigerator was not properly cooling. Found door leakage, ordered the part, and returned to replace the seal. No markup on the part, no added time to repair - entire transaction was very fair. Could not ask for a better experience."
