“I had the best experience with Rei from One Hour Heating & Air Conditioning. From the moment he arrived, Rei was professional, courteous, and incredibly knowledgeable. He took the time to explain the issue in simple terms, offered honest recommendations, and worked efficiently to resolve everything on the spot. What truly stood out was his attention to detail and commitment to making sure everything was running perfectly before he left. It’s rare to find someone who combines technical expertise with such great customer service. Rei made what could’ve been a stressful situation completely hassle-free. I highly recommend him and will definitely be requesting him for any future service.”
