What Our Clients Say…
  • I would like to express my highest appreciation to Core One Mechanical Group Inc. on their timely and precise responses to a partial cooling deficiency that occurred on the night of April 18th, 2016 at our location. Cory Snider did a thorough evaluation and restoration of the defunct cooling circuit of AHU-10, noting he was able to secure tools and materials at the middle of the night, Sam Doosti did an expedient technical support on the phone during first respond, and Doug Dewar manned the most needed Command Center. Well done! Kudos! You’re truly a PYCRO – a Partner You Can Rely On!–Darren K.
