Mr. Ivanchenkov was fantastic. Our condensor compressor kicked the can, and he made sure to come back the very next day with the new one to install. We went 4 days without AC during a heat wave, and my wife was 8 months pregnant at the time so we were extremely thankful. He was very polite and great to talk with. Very down to earth dude who knew what he was doing. He also helped instructing a “helper” who I believe is getting on the job training. I have nothing critical to say of the guy.
