I have been using C.& J. Air since 1993. They continue to be the best service provider I use. They sent me a notice about the twice a year Precision Tune-Up and I called and scheduled right away. The day they came and serviced my A/C unit Alex was right on time, he called before he showed up and as always he got the job done. He cleaned the leaves out of my outside unit which I know will prolong the life of my compressor. He even finished by vacuuming the last part of them out. He flushed out/blew out my drain and checked everything to make sure nothing was wrong. He even changed out my air filter for me. C&J has always been a competent and trustworthy source to get the job done. I won't use anyone else and haven't for 28 years.
