HVAC

Cissell Investigative Engineering LLC (CIE) is fortunate to have two seasoned experts on these issues.  One expert holds and maintains licenses on HVAC, plumbing, boilers and furnaces.  Experience in the energy delivery and system maintenance is invaluable.  His almost encyclopedic knowledge of discontinued systems provides a tremendously efficient service to our clients.  The professional engineer gained most of his experience on power plant systems, trouble shooting startups and failures.  Together, they are an extremely efficient team, capable of resolving complex failures as well as the more routine.

The common Fire Protection systems, other than kitchen hood,  are either usually wet or dry water systems.  Most of the problems CIE has found with these systems are with the dry systems staying flooded and freezing.  We frequently find simple design or installation errors that prevent proper draining after testing.  CIE has frequently uncovered design flaws that would have prevented proper operation of the system during freezing weather.

Kitchen hoods an suppression systems are examined when a fire escapes the hood area and causes an uncontrolled fire.  CIE has found sign-offs by technicians where the system didn’t contain all of the heating appliances, and where the system was designed for lard fire suppression but not for vegetable oil.  Examination of several exhaust ducts found them too close to combustibles and a number of other failures.

  1. Thank your for the info. I would like to add that the main reason behind the sudden failure of HVAC system is the lack of maintenance. It is important to combat this root cause by sticking to the basics. Thank your for the info.
