I highly recommend CerProTech! I had been jerked around by several other companies with higher quotes to repair my A/C and then I found CerProTech. Olaf Marek was willing to come out late on a Friday and offered a cheaper solution than the other companies. He was really nice and very helpful. He even offered a 1 year parts and labor guarantee as well! He was very trustworthy and very quick to fix the issue, and charged less than half of the other companies.
