The technicians are knowledgeable and professional which is very important to us. They get right to work and don’t waste any time. When I call Donnelly, they’re here within the hour. Before, I had to wait 5 to 6 hours and it took 3 visits before they were able to fix the problem. Donnelly does it in one. I do a lot of networking and deal with a lot of facilities managers and everyone says how Donnelly is one of the best companies out there. You can see it – their trucks are all over. When I ask people, who’s your air conditioning provider, they all say Donnelly. It’s not often that at a big company like this you get to speak with the owner one-on-one. That’s something that is very good to have. Dino will be more than happy to come down, shake your hand, have a cup of coffee with you. And that’s great.
