I highly recommend Frank and South Side Air Conditioning and Heating. I called Frank at 9 AM and he said they would be by our house at about 11 AM to diagnose the problem. Promptly at 10:58 AM, they arrived as promised. While my experience with other companies would have required a new compressor at approx. $3,000, Frank explained all of the options and we chose to fix our current compressor and pay as little as 1/6 of the price of a new compressor. If you are looking for prompt, knowledgeable, courteous, reasonable and honest a/c and heating repair - Frank at South Side Air Conditioning and Heating will be your next phone call!
