“I purchased this item after the A/C company came and installed one on my unit in the middle of the summer. I live in Texas so the A/C is a must. The temperature was 108 degrees so I needed it fixed fast and I paid the price..This exact item cost me $560 but thanks to you, That will never happen again.. Thank you so much..”

“One review said it was aluminum wire, which is false. Silver plated copper wire combines conductivity and durability at a lower cost than pure silver wire.”
