I felt a sense of honesty from the guy at CR Custom Services. I have a brief understanding about AC systems and everything he told me was the truth. He didn't try to sell me things that were false. He replaced the thermal expansion valve (txv), the dryer, the fan and recharged the system. I called two other companies before him, but I didn't believe what they said. They also had diagnosed the problem incorrectly. Everything turned out excellent and we had a pretty good time together!
