I would like to take the time to commend your amazing staff. I’ve had the pleasure of working with the Donnelly team on our recent move to 3 World Trade Center. I was very hesitant about working with a new mechanical contractor but I can confidently say my hesitations were put at ease immediately. The Donnelly team has taken their time to educate and guide me, and make repairs on many issues that were above and beyond their maintenance scope. Joe, Ravi and their colleagues have shown a top notch level of expertise. We are very fortunate to have such a knowledgeable team of HVAC technicians at our disposal.
