"Charles was out to do maintenance on our system. We are new to the area and I absolutely loved him. I didn't even know we had a humidifier on our system. Charles explained everything to us and cleaned everything up for us. He found a small leak and sealed it and told me to keep an eye on it to make sure it was not leaking. I was VERY happy with him! I was impressed that he didn't just try to sell me a new part or new system."
