"The service tech(Chris) was very courteous and knowledgeable. I told him before he came that the fan was running intermittently. He said he would be out in the morning with the motor in case that was the problem. Turns out the fan was fine and it was a solenoid that was bad. He could have replaced the fan and the solenoid and made more money for himself and the company. He just replaced the bad solenoid. He fixed my AC in less than half a day during a heat wave and saved me money! If anybody asked if I know good and honest HVAC place I will recommend "Generations"."

He made sure the system was running properly before leaving and left the work area spotless. Our house is cooling perfectly now.
