MJ Mechanical Services was founded in 1977. Since then MJ Mechanical has been one of the leading commercial and industrial mechanical contractors in Western New York (WNY). We are dedicated and highly trained heating, ventilation and air conditioning (HVAC) contractors. Over the past 40 years, MJ Mechanical has grown to become Western New York’s leader as a single source contractor by expanding the following departments: Service, Controls, Balancing (NEBB certified), Installation, Fabrication, Boiler Retubing and Refractory.  We have maintained that status by exceeding the expectations of our customers.  In 1998, MJ Mechanical joined Comfort Systems USA, an organization of leading specialty contractors across the country.  This partnership with our sister companies of Comfort Systems USA enables us to diversify our expertise and manpower for any given situation or location.  Our commitment to quality, innovation, and safety will ensure that all of your HVAC or process needs are met.  If you are looking for a heating, ventilation, and air conditioning (HVAC) contractor for your industrial or commercial needs, MJ Mechanical is the preferred contractor of choice.
