“This was my first experience with One Hour Heating and Air Conditioning and I must say, I was impressed. My technician, Wael, arrived on time, and was both courteous and professional; but what impressed me the most was how knowledgeable he was. He went about diagnosing my AC trouble methodically. Once complete, Wael reviewed his findings and the associated cost for each repair item with me. He secured my sign-off before proceeding, and completed the work in a timely manner. I would absolutely hire One Hour Heating and Air Conditioning again. ☆☆☆☆☆”
