New York City’s leading authority in high efficiency HVAC systems and upgrades

Design, installation, and maintenance of high-efficiency commercial HVAC systems.

With over 30 years of experience working with owners, managers and contractors of large buildings, Donnelly can design, install, and maintain high-efficiency commercial HVAC systems that improve building performance and deliver the highest return on building investment.

Better Performance, Lower Costs

Installing high efficiency HVAC systems in new construction, or retrofitting existing buildings with high-efficiency upgrades, allows you to effectively manage energy consumption, leading to better indoor air quality, lower costs, and a reduced carbon footprint.

Along with regularly scheduled preventative maintenance, your high efficiency HVAC system can actually lower your total energy consumption by up to 50%. This is particularly significant during peak summer months when your new system can save you minimally 15% off of your utility bill, potentially freeing thousands of dollars to allocate elsewhere.

Energy Efficient Incentives

Energy Assessment

Donnelly’s hands-on energy assessment evaluates all the equipment and components that are part of your building’s HVAC system.
