Turn-Key Replacements and High Efficiency System Upgrades

Donnelly Mechanical’s Special Projects team is committed to delivering intelligent HVAC solutions.

Our primary focus is to provide support and resources for mechanical systems that are above and beyond the general maintenance and repair services scope. From beginning to end, Donnelly’s Project Management team takes a high-level view to ensure that your HVAC equipment delivers sustainable, comfortable air throughout your commercial building while maintaining the life and performance of the system. Taking this strategic view ensures that your entire facility and all of its moving parts work together to achieve the common goal. We enjoy the challenge of determining an intelligent solution not only to replace failed equipment, but to improve the operation of the facility when designing and installing a system.

From supplemental HVAC installations to 500-ton chiller replacements, we have you covered. Our turnkey approach allows for a single point of contact for all trades and processes throughout the duration of the project.

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.
