Our Clients Come First – This is the Donnelly Difference.

Clients come first at Donnelly Mechanical. We pride ourselves on our ability to provide them innovative solutions and strive to exceed their expectations with the highest level of professionalism, teamwork and integrity.

Here are some first-hand testimonials from some of the most elite addresses in Manhattan:

Every year we bring Donnelly in to do a full diagnostic survey of all the equipment and then we make adjustments. Since the relationship started in 2002, we have not had a machine down.

Immediately after Sandy, Donnelly came in and demolished the submerged units, removed them and started to rebuild them so we could be up and running. We were the first building lit on generator power after the storm.

Donnelly was there when we needed them most. Donnelly’s there when we just need them. We all work really well together.

DELOY STOLL – BUILDING MANAGER, 17 STATE STREET

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, Dan will be more than happy to come down, shake your hand, have a cup of coffee with you. And that’s great.

I find Donnelly Mechanical to be outstanding in regards to their service department. I had a specific service coordinator that I deal with all the time. I also have a dedicated technician that has been working here for 8 years. I’m very pleased with him, he brings anything I need to know about to my attention. He’s just a phone call away and he always finds the problem and resolves it so that there are no future issues. So based on that, that’s why we continue to use Donnelly Mechanical. It’s a huge help having the same technician here every time because he knows where all the units are and I can trust that he will get the job done efficiently.

When Hurricane Irene came, they called us up to actually see how we were doing… they were there to help us if we needed storage space or any other kind of assistance. We didn’t even have to call them, they showed concern for their client. That was very impressive.
