IT TOOK OVER A MONTH TO REPAIR MY A/C. THE TECH ON SITE SAID THAT HE HAD TO GET PERMISSION TO ADVANCE TO THE NEXT REPAIR PROCESS. HIS FIRST VISIT DETERMINED THAT MY FREON WAS VERY LOW. HE NEEDED PERMISSION TO DO A LEAK CHECK. THAT MEANT THAT I HAD GET BACK INTO LINE WITH HIS SCHEDULER. T THIS HAPPENED 4 TIMES User's recommendation: TO PRE AUTHORIZE WHATEVER REPAIRS HAVE TO BE DONE.
