I called Hendrix Air because my air conditioner had stopped working. They came out the next day. They were very efficient. Even wore booties over their shoes so they wouldn't track anything into the house. They found the problem to be a short. My water conditioning system had shorted out the air conditioning unit. They immediately disconnected everything and turned off the breaker until I could get somebody out here to fix the water system. Once that was fixed, they came back and made sure my air conditioner was working fine. The best part is that I have a customer care card, where they do a couple service calls a year for me, so it was no charge. I highly recommend them.
