Many HVAC investigation specific firms send a local affiliated technician out to a site to evaluate systems and equipment before an engineer performs a desk review of submitted materials.  When EIS accepts an assignment, a licensed professional engineer is onsite, leading the investigation team from the inspection phase through issuance of an engineering report.  This is of particular importance in large losses and construction defect HVAC claims, where legal action is often of concern.  Should a claim move toward litigation, EIS has the experience working with attorneys and the focused understanding of HVAC and plumbing systems to provide accurate expert witness testimony.
