Core Drilling for HVAC

HVAC installations require precise penetrations through concrete walls, floors, and foundations for ductwork, refrigerant piping, condensate lines, exhaust venting, and fresh air intakes. REDCORE provides diamond core drilling services designed specifically for HVAC contractors, delivering clean, accurately sized and positioned holes that meet the exact specifications of the mechanical installation. From small 3-inch penetrations for mini split line sets to large 24-inch cores for commercial duct runs, we drill every hole with the precision that proper HVAC installation demands.

Our core drilling operators understand HVAC requirements including proper hole sizing for different duct diameters, the importance of maintaining fire-rated wall assemblies, sleeve clearances for insulated piping, and the need for slight pitch on penetrations to allow condensate drainage. We coordinate directly with HVAC technicians to ensure every penetration is in the right location, at the right height, at the right diameter, and at the right angle. This level of coordination prevents costly rework and keeps your mechanical installation on schedule.

REDCORE serves HVAC contractors throughout Massachusetts with core drilling for residential systems, commercial rooftop units, industrial ventilation, and everything in between. We also drill penetrations for exhaust fans, range hood venting, bathroom fan ducting, and combustion air intakes. One call provides all the concrete penetrations your HVAC project requires.
