BEWARE OF PRIORITY SERVICES INSPECTION OF YOUR AIR CONDITIONING SYSTEM. THINGS WILL BE FINE UNTIL THEY COME, INSPECT AND THEN ALL OF A SUDDEN SOMETHING IS WRONG. They did a inspection of my system which was working fine then the next day I had a problem. Called them back and they quoted me some ridiculous price to fix the problem so i called another company to compare. I was told this happens frequently and that the problem I had couldn't have happened unless the unit was tampered with. the third vendor confirmed this to be true. BEWARE...DON'T USE THEM!!
