Carl and his partner were quick and efficient.. after I told them what was going on, he asked a few questions and told me it was probably low on Freon. That was the case. I had met Carl before when I worked for Ameren and he had been called to fix problems at customers houses that I had shut off for gas leaks or other problems. Glad to see him and the two have my house cool again in this heat!! Will call your company again in the future if the need arises. Thanks!!!! Jim Siebert
