Unparalleled Commercial HVAC Solutions. Here for You, 24/7.
New York City commercial facilities face unique challenges on a daily basis — and commercial HVAC issues are no exception. When you work with Donnelly, we help you focus less on HVAC issues so you can focus more on the day-to-day functions of your business. Our trained technicians at Donnelly work ardently to provide you with the most specialized service.
We serve NYC’s most prominent commercial organizations by providing innovative HVAC solutions to ensure comfort, maximum efficiency, improved indoor air quality and system reliability. From Class-A office spaces, to data centers to healthcare facilities, we’re committed to providing the most reliable HVAC service across Metro New York.
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.
