Donnelly Mechanical Corporation has been providing heating and cooling solutions to the New York metropolitan area since 1989. The recipient of many awards for service excellence, including the 1994 and 1995 Staples "The Office Superstore" MVP award for distinguished service and quality control along with Contractor of The Year by the United Service Alliance, Donnelly Mechanical has become one of the leading HVAC contractors in the NYC area.
We will satisfy all of your HVAC needs from service contracts to new construction, including engineering and/or design problems. Our commitment to quality control and prompt service is at the foundation of our success.
Today most heating and air conditioning companies focus on volume and have lost sight of the relationship between a company and its customers. Customer service is our highest priority, and it shows. We offer 24 hour emergency service 7 days a week, 365 days a year. If you want smart, swift and cost-effective HVAC solutions - without red tape, excuses, or runarounds - make sure to call us first!
