William B assisted us with our upstairs air conditioning. He took the time to show me what was going on with my AC system and explained what was going on that was making it not work correctly. He diagnosed the problem and fixed it quickly. He did a great job and I feel like he is very trustworthy. He even helped us set up a maintenance plan so that they can inspect our system twice a year to ensure it is running properly.Pernell is a great company and we will continue to use them.
