My air conditioner went out and I had to call Windy City Air Conditioning & Heating. There are limited companies that will deal with mobile home air conditioning units in my area. The technician arrived on time and walked me through what the issues were. He said the air conditioner was on its way out but managed to do some work on it to get it running. He did give me some options for replacement and have not made a decision on which route I will take. Overall, the service was good even if I didn't like the diagnosis.
