HVAC Replacement Engineering

Replacing HVAC equipment in an existing commercial building often requires mechanical engineering — confirming the replacement equipment is correctly sized, verifying structural capacity for new rooftop equipment, and producing permit drawings when the jurisdiction requires them. Apex Grid engineers HVAC replacements efficiently, working from existing building information to produce what's needed for permit.
