I have a central cooling unit and it was working great until it didn't. It would stop working randomly in the middle of the day, in the middle of July. The house got up to 90 degrees and we have a new born so I tried using a company called mechanical control solutions, I asked for a time after I got out of work, as no one would be home before then, I received a call and the tech was rude, told my I only had a one option and that was way before I got off work and told me " that's your problem figure it out". I have them two more chances and was moved both times. I called Indoor comfort and Lou answered and it was like night and day. He came out as soon as he could, checked everything, and we couldn't figure it out. He wanted to wait and see how it was working. Lou called me multiple times to check on it, giving me advice and tips to try early in the mornings and even later into the nights. We figured out that there was a cover over my compressor, and he came and took it off for me, and did it all on his own time to make sure that we had a cool house for my family. He's also checked on it since to sure it's running well. I couldn't be happier with his services and would recommend him to anyone and everyone.
