They charge $90 per hour. What a JOKE! While I was away, they didnt call me before repairs were made and they didnt call after the repairs were made. I had to keep calling them to get a status. When I got home my A/C still wasn't working. So they essentially fixed something that wasn't broken and tweeked my A/C. When I called them back to tell them it wasnt working again, the service man came back and soaked me for another hour or two. My A/C worked again for a about 2 hours after he left and then stopped. All he could me me was that my A/C unit was old but he never said it was unfixable. I stopped calling them after the second time. Then they sent me a bill for $312.00 THANKS FOR NOTHING. Buyer Beware!
