My a/c went out at my house. DND came out and instead of telling me I needed a new unit (like every other a/c company), they found the problem, changed the part, and it's working great now. These guys are honest and very dependable. I highly recommend them!

The BEST a/c company! My restaurant a/c wasn't working very well. One of my friends mentioned D-N-D so I called them. Brian (totally awesome guy!) came out and cleaned my unit up on the roof. My a/c is working like a charm now! This company is dependable, honest, and didn't make me feel ignorant for not knowing why my a/c wasn't working. I HIGHLY recommend D-N-D.

Michael Taylor

We've used their company twice. They are friendly and fast! My central AC system failed yesterday. I called this morning. They fixed it today! He gave some pricing information on new systems and good advice also.
