All of the reviews make me think these guys must be okay. However, the soonest they could come see me was five days from when I was calling. I made the appointment then went to Youtube. The AC fan outside wasn't spinning and was making a hum/buzz. YouTube said it was the dual run capacitor. I went and bought one for $50, 4 wires moved, and bam, problem solved. They inspired me to do it myself, I can appreciate that. I called them and cancelled my appointment. Next time I have a problem and can't figure it out with Google and YouTube I will give these guys another shot.
